WEBVTT 1 00:00:00.080 --> 00:00:02.359 Welcome to our deep dive. Today. We're going to be 2 00:00:02.359 --> 00:00:05.080 exploring how your devices connect to the Internet and with 3 00:00:05.200 --> 00:00:08.199 each other. It's exciting, it is, and we're using Professor 4 00:00:08.240 --> 00:00:12.359 messrs Comtia plus training notes as our guide. It's a 5 00:00:12.400 --> 00:00:14.960 really great resource, even for non techi is. It breaks 6 00:00:15.000 --> 00:00:17.559 down like these really complex concepts in a way that 7 00:00:17.600 --> 00:00:18.679 anyone can understand. 8 00:00:18.760 --> 00:00:19.879 Yeah. I've used it myself. 9 00:00:20.039 --> 00:00:22.920 Yeah, and so that's exactly what we're aiming to do today, 10 00:00:23.000 --> 00:00:26.120 give you a really clear picture of how mobile devices 11 00:00:26.120 --> 00:00:29.199 and networks actually work. So let's start with something you 12 00:00:29.280 --> 00:00:32.520 use every day, your laptop. Have you ever stopped to 13 00:00:32.560 --> 00:00:36.359 think about what's actually happening inside that sleek machine when 14 00:00:36.399 --> 00:00:38.159 you browse the web or stream of video? 15 00:00:38.560 --> 00:00:39.600 I mean most people don't. 16 00:00:39.880 --> 00:00:42.359 No, I don't think they do. Well, get this. Some 17 00:00:42.560 --> 00:00:45.000 laptops now come with o LED screens, which is the 18 00:00:45.039 --> 00:00:48.320 same technology that's used in like those high endtvs that 19 00:00:48.399 --> 00:00:53.159 have those incredible contrast in deep blacks. Oh wow, I know, right, 20 00:00:53.399 --> 00:00:55.399 and your Wi Fi antenna it could be right there 21 00:00:55.399 --> 00:00:56.280 wrapped around your screen. 22 00:00:56.479 --> 00:00:57.479 Really yeah. 23 00:00:57.679 --> 00:01:01.079 I always find those little details so fascinated. But they're 24 00:01:01.119 --> 00:01:04.400 more than just cool trivia knowing what's inside your laptop 25 00:01:04.439 --> 00:01:07.439 can actually help you make smarter choices when you're buying 26 00:01:07.480 --> 00:01:11.599 a new one, or even when you're troubleshooting a problem. 27 00:01:11.719 --> 00:01:12.439 That's a good point. 28 00:01:12.480 --> 00:01:14.280 For example, have you heard of SSDs? 29 00:01:14.519 --> 00:01:16.280 Yeah, solid state drives exactly. 30 00:01:16.280 --> 00:01:19.439 They stand for solid state drives and they're basically the 31 00:01:19.599 --> 00:01:23.000 rock stars of data storage these days. Instead of relying 32 00:01:23.040 --> 00:01:27.920 on those spinning discs like the traditional hard drives, SSDs 33 00:01:28.040 --> 00:01:31.079 use flash memory, so there are no moving parts. So 34 00:01:31.120 --> 00:01:33.200 that makes them much faster, quieter, and. 35 00:01:33.120 --> 00:01:34.760 More durable, much more durable. 36 00:01:34.840 --> 00:01:38.120 It's really like comparing a high speed train to a 37 00:01:38.159 --> 00:01:39.280 horse drawn carriage. 38 00:01:39.400 --> 00:01:40.439 Yeah, it's a big difference. 39 00:01:40.640 --> 00:01:42.599 But what does that mean for you in practical terms? 40 00:01:43.319 --> 00:01:45.519 Well, imagine this. You click on an app and it 41 00:01:45.560 --> 00:01:48.239 opens instantly, no more waiting for what felt like an 42 00:01:48.239 --> 00:01:50.560 eternity while your computer struggled to load. 43 00:01:50.719 --> 00:01:54.959 Oh I remember those days. Yeah. SSDs make everything snappier, 44 00:01:55.239 --> 00:02:00.200 from booting up to launching applications to transferring files. You'll 45 00:02:00.239 --> 00:02:03.920 actually feel the difference in your daily use. It's that significant. 46 00:02:03.959 --> 00:02:05.680 Remember those days when you'd make a cup of coffee 47 00:02:05.719 --> 00:02:09.400 while waiting for your computer to beat up? Oh yeah, yeah, well, 48 00:02:09.439 --> 00:02:11.680 those days are gone thanks to SSDs, and that's just 49 00:02:11.719 --> 00:02:14.800 one example of how understanding the components inside your laptop 50 00:02:14.840 --> 00:02:18.439 can make a big difference. But enough about the hardware inside. 51 00:02:18.759 --> 00:02:21.120 Let's move on to how your laptop connects to the world. 52 00:02:22.000 --> 00:02:24.319 We all love wireless connections, right, Oh. 53 00:02:24.360 --> 00:02:24.919 Absolutely. 54 00:02:24.919 --> 00:02:27.639 The freedom to work from anywhere without being tethered to 55 00:02:27.680 --> 00:02:29.159 a desk is pretty amazing. 56 00:02:29.319 --> 00:02:30.840 Yeah, I can't imagine going back. 57 00:02:30.719 --> 00:02:34.159 I know, right, but wireless networks can be a bit 58 00:02:34.199 --> 00:02:35.919 of a mystery, even though we use them all the time. 59 00:02:36.080 --> 00:02:36.520 Definitely. 60 00:02:36.560 --> 00:02:39.879 There's a whole alphabet soup of Wi Fi standards aoh 61 00:02:39.960 --> 00:02:43.439 two point eleven, a b G, NAC, and now we 62 00:02:43.479 --> 00:02:46.080 even have Wi Fi six or Wi Fi six E. 63 00:02:46.919 --> 00:02:48.120 It's enough to make your head spin. 64 00:02:48.240 --> 00:02:49.439 Yeah, it's hard to keep track. 65 00:02:49.400 --> 00:02:51.520 I know, But here's what you really need to know. 66 00:02:52.000 --> 00:02:55.840 Each new standard brought faster speeds and better performance. But 67 00:02:55.879 --> 00:02:57.599 that doesn't mean you need to rush out and buy 68 00:02:57.639 --> 00:02:59.960 a new router every time a new standard comes out. 69 00:03:00.120 --> 00:03:01.280 Yeah, that's good advice. 70 00:03:01.639 --> 00:03:06.280 What matters most is understanding the practical implications. For instance, 71 00:03:06.599 --> 00:03:09.120 did you know there are actually two different frequency bands 72 00:03:09.159 --> 00:03:11.759 that are commonly used for Wi Fi oh right, two 73 00:03:11.800 --> 00:03:13.919 point four gigaherts and five gigahertz. 74 00:03:14.439 --> 00:03:14.639 Yeah. 75 00:03:14.800 --> 00:03:17.639 Think of it like having two different highways. The two 76 00:03:17.639 --> 00:03:20.680 point four gigahertz ban is like a wider highway with 77 00:03:20.759 --> 00:03:23.879 more lanes but a lower speed limit. It has a 78 00:03:23.919 --> 00:03:27.159 longer range, but can get congested with traffic from other devices. 79 00:03:27.360 --> 00:03:27.960 Ah okay. 80 00:03:28.080 --> 00:03:31.280 The five gigaheads ban is like a narrower highway with 81 00:03:31.400 --> 00:03:34.479 fewer lanes but a much higher speed limit. It's faster, 82 00:03:34.680 --> 00:03:36.719 but has a shorter range and can be more easily 83 00:03:36.759 --> 00:03:39.919 blocked by obstacles like walls. Makes sense, So which one 84 00:03:39.960 --> 00:03:42.520 did you use? Well, it depends on your needs. If 85 00:03:42.520 --> 00:03:44.599 you're close to the router and need the fastest speeds, 86 00:03:44.719 --> 00:03:46.719 five gegter hertz is the way to go. But if 87 00:03:46.759 --> 00:03:48.840 you're farther away or have a lot of walls between 88 00:03:48.879 --> 00:03:50.599 you and the router, you might get a more stable 89 00:03:50.599 --> 00:03:52.400 connection with two point four gigaherts. 90 00:03:52.520 --> 00:03:53.360 That's a good tip. 91 00:03:53.800 --> 00:03:55.840 And here's a pro tip. If you're ever struggling with 92 00:03:55.879 --> 00:04:00.599 a slow or unreliable Wi Fi connection, try switching to 93 00:04:00.639 --> 00:04:04.039 a different channel. It's like changing lanes on a crowded 94 00:04:04.080 --> 00:04:08.680 highway to avoid a traffic jam. Now, speaking of wireless connections. 95 00:04:08.680 --> 00:04:12.240 We can't forget about cellular networks. Remember the days of 96 00:04:12.280 --> 00:04:14.280 two G when all you could do was send text 97 00:04:14.319 --> 00:04:17.560 messages and make calls. Oh yeah, Then came three G, 98 00:04:17.959 --> 00:04:21.360 which brought us mobile internet and the ability to browse 99 00:04:21.399 --> 00:04:23.959 the web on our phones. Four G was a game 100 00:04:24.040 --> 00:04:27.240 changer for streaming video and music, and now we have 101 00:04:27.319 --> 00:04:31.560 five G, which promises even faster speeds and lower latency. 102 00:04:31.560 --> 00:04:34.120 Seeing how far we've come, I know, right, But. 103 00:04:34.120 --> 00:04:37.399 FIG isn't just about speed. It's also about connecting a 104 00:04:37.600 --> 00:04:40.720 massive number of devices, everything from your phone and laptop 105 00:04:40.759 --> 00:04:42.879 to your smart home appliances and even your car. 106 00:04:43.040 --> 00:04:44.959 Yeah, the Internet of things exactly. 107 00:04:45.000 --> 00:04:46.879 This is what's known as the Internet of Things, and 108 00:04:47.319 --> 00:04:49.920 it's rapidly changing the way we live and interact with 109 00:04:49.959 --> 00:04:50.720 the world around us. 110 00:04:50.720 --> 00:04:51.319 It really is. 111 00:04:51.519 --> 00:04:56.160 But to really appreciate the power of five G and 112 00:04:56.319 --> 00:04:58.879 the Internet of Things, we need to dive a bit 113 00:04:58.959 --> 00:05:02.959 deeper into how networks actually work, and that means talking 114 00:05:03.000 --> 00:05:06.160 about some of the technical terms that often make people's 115 00:05:06.199 --> 00:05:10.199 eyes glaze over, things like IP addresses, ports, and protocols. 116 00:05:10.360 --> 00:05:11.959 Yeah, those can be a bit intimidating. 117 00:05:12.079 --> 00:05:14.600 I know, I know, it sounds intimidating. But trust me, 118 00:05:14.720 --> 00:05:18.000 it's not as complicated as it seems. Let's break it down. 119 00:05:18.879 --> 00:05:21.439 Think of it like sending a package. The IP address 120 00:05:21.600 --> 00:05:24.439 is like the street address. It tells your data where 121 00:05:24.480 --> 00:05:27.319 to go okay. The port is like the specific apartment 122 00:05:27.439 --> 00:05:30.839 number within that building. It tells your data which application 123 00:05:30.959 --> 00:05:34.040 or service it's intended for ahee. And the protocol is 124 00:05:34.079 --> 00:05:37.000 like the delivery service. It defines the rules and format 125 00:05:37.040 --> 00:05:39.079 for how that data is packaged and sent. 126 00:05:39.199 --> 00:05:40.079 It's a good analogy. 127 00:05:40.240 --> 00:05:42.360 Two of the most common protocols you'll hear about are 128 00:05:42.399 --> 00:05:46.279 TCP and UDP. TCP is like a registered letter. It's 129 00:05:46.360 --> 00:05:48.920 reliable and guarantees that your data will arrive safely, but 130 00:05:48.920 --> 00:05:52.439 it's a bit slower. UDP is like a postcard. It's faster, 131 00:05:52.600 --> 00:05:55.519 but there's no guarantee that it will arrive. So TCP 132 00:05:55.720 --> 00:05:58.480 is used for things like email and online banking, where 133 00:05:58.600 --> 00:06:02.519 reliability is crucial, while UDT is used for things like 134 00:06:02.639 --> 00:06:05.680 video streaming and online gaming, where speed is more important 135 00:06:05.720 --> 00:06:06.839 than guaranteed delivery. 136 00:06:06.959 --> 00:06:07.600 That makes sense. 137 00:06:07.839 --> 00:06:10.560 Now, you might be thinking, but how does my data 138 00:06:10.639 --> 00:06:13.040 stay safe when it's traveling all over the internet. 139 00:06:13.120 --> 00:06:14.120 Yeah, that's a good question. 140 00:06:14.360 --> 00:06:17.680 Well, that's where firewalls and NAT come in. They act 141 00:06:17.759 --> 00:06:20.680 like security guards for your network, protecting you from unwanted 142 00:06:20.720 --> 00:06:25.040 visitors and malicious attacks. Imagine each application on your computer 143 00:06:25.240 --> 00:06:27.759 is a room in your house, and each port is 144 00:06:27.800 --> 00:06:31.160 a door. A firewall controls who can come in and 145 00:06:31.199 --> 00:06:35.360 out of which rooms, making sure only authorized guests have access. Okay, 146 00:06:35.560 --> 00:06:39.160 NAT stands for Network Address translation, and it's a bit 147 00:06:39.160 --> 00:06:42.279 more technical, but essentially, it helps to hide your devices 148 00:06:42.279 --> 00:06:44.720 from the outside world by giving them a single public 149 00:06:44.759 --> 00:06:48.240 IP address. Okay, it's like having a single mailbox for 150 00:06:48.279 --> 00:06:51.800 your entire household, even though you have multiple people living there. No. 151 00:06:52.480 --> 00:06:54.879 I know we've covered a lot of ground already, but 152 00:06:54.959 --> 00:06:56.600 before we move on, I want to make sure you 153 00:06:56.600 --> 00:07:00.639 feel comfortable with these basic concepts. Does anything we've discussed 154 00:07:00.639 --> 00:07:04.040 so far stand out to you as particularly interesting or confusing? 155 00:07:04.959 --> 00:07:07.800 What questions do you have about how your laptop connects 156 00:07:07.800 --> 00:07:09.319 to the internet and other devices? 157 00:07:10.959 --> 00:07:16.000 Well, I think I'm following so far, but can we 158 00:07:16.000 --> 00:07:17.959 talk a little bit more about troubleshooting? 159 00:07:18.160 --> 00:07:20.839 Yeah? Sure, so far we've been talking about all the 160 00:07:20.879 --> 00:07:23.240 amazing things that can go right when your devices connect 161 00:07:23.240 --> 00:07:27.279 and communicate. But let's face it, technology isn't perfect. Things 162 00:07:27.360 --> 00:07:29.560 can and do go wrong, and sometimes it feels like 163 00:07:29.600 --> 00:07:32.360 our devices have a mind of their own. Oh yeah, 164 00:07:31.839 --> 00:07:35.000 but before you throw your laptop out the window or 165 00:07:35.040 --> 00:07:37.720 toss your phone in the trash, let's equip you with 166 00:07:37.800 --> 00:07:41.879 some troubleshooting superpowers, because often fixing those tech hiccups is 167 00:07:42.279 --> 00:07:43.199 easier than you think. 168 00:07:43.399 --> 00:07:43.879 I hope so. 169 00:07:44.160 --> 00:07:47.560 And let's be honest, there's a certain satisfaction that comes 170 00:07:47.600 --> 00:07:49.079 from figuring. 171 00:07:48.680 --> 00:07:49.399 It out yourself. 172 00:07:49.720 --> 00:07:53.199 Absolutely, It's like solving a puzzle or cracking a code. 173 00:07:53.720 --> 00:07:54.839 Yeah, it's a good feel. 174 00:07:55.000 --> 00:07:57.079 So where do we start. Well, let's begin with some 175 00:07:57.120 --> 00:08:00.399 common laptop problems that you can tackle head on. First 176 00:08:00.439 --> 00:08:04.680 things first, no power. It sounds obvious, but you'd be 177 00:08:04.720 --> 00:08:06.920 surprised how many times as simple fix is all it 178 00:08:06.959 --> 00:08:10.680 takes is your laptop plugged in, is the battery charged? 179 00:08:11.160 --> 00:08:14.160 Sometimes we overcomplicate things when the solution is right in 180 00:08:14.160 --> 00:08:14.680 front of us. 181 00:08:14.720 --> 00:08:16.399 I've definitely done that before. Yeah. 182 00:08:16.639 --> 00:08:20.319 Another common issue is overheating. If your laptop feels like 183 00:08:20.360 --> 00:08:23.079 it's about to burst into flames, it's time to check 184 00:08:23.079 --> 00:08:26.199 the fans and heat sinks. Dust build up can block 185 00:08:26.279 --> 00:08:29.439 airflow and cause components to overheat. So little cleaning goes 186 00:08:29.439 --> 00:08:32.720 a long way good. And speaking of noises, what about 187 00:08:32.759 --> 00:08:36.360 those strange sounds that laptops sometimes make. Oh yeah, a 188 00:08:36.440 --> 00:08:40.120 rattling sound could mean loose components, while a scraping sound 189 00:08:40.200 --> 00:08:44.000 might indicate a hard drive issue. And if you hear 190 00:08:44.039 --> 00:08:47.399 a clicking sound, especially that dreaded click of death, it 191 00:08:47.440 --> 00:08:49.000 could be a sign of a failing hard drive. 192 00:08:49.120 --> 00:08:50.240 Oh no. 193 00:08:50.240 --> 00:08:52.360 Now, let's say your laptop turns on but the screen 194 00:08:52.480 --> 00:08:56.679 stays blank. Don't panic just yet. First check the brightness settings. 195 00:08:56.759 --> 00:08:59.039 Maybe you accidentally hit the wrong key and dimmed the 196 00:08:59.039 --> 00:08:59.960 screen all the way down. 197 00:09:00.440 --> 00:09:01.320 Yeah, that happens. 198 00:09:01.480 --> 00:09:03.600 If that's not it, it could be a problem with 199 00:09:03.679 --> 00:09:07.200 the video cable, the monitor itself, or even the graphics card. 200 00:09:07.840 --> 00:09:10.399 Try connecting an external monitor to see if that works. 201 00:09:11.000 --> 00:09:12.960 If it does, then you know the problem is isolated 202 00:09:12.960 --> 00:09:16.440 to your laptops built in screen. Okay, speaking of isolations, 203 00:09:16.480 --> 00:09:19.799 sometimes problems are caused by software conflicts or bad drivers. 204 00:09:21.320 --> 00:09:23.720 Software the invisible Grimlin of the tech world. 205 00:09:24.000 --> 00:09:24.120 Right. 206 00:09:24.320 --> 00:09:27.919 If you suspect a software issue, try booting into safe mode, 207 00:09:28.120 --> 00:09:32.240 which loads only the essential drivers and programs. If that works, 208 00:09:32.480 --> 00:09:34.759 then you know it's a problem with some other software 209 00:09:34.879 --> 00:09:38.360 setting that you've installed. And don't forget about those little 210 00:09:38.360 --> 00:09:41.159 indicator lights on your laptop and motherboard. They can be 211 00:09:41.240 --> 00:09:44.120 like cryptic messages, but once you learn to decode them, 212 00:09:44.279 --> 00:09:46.279 they can tell you a lot about what's going on. 213 00:09:46.360 --> 00:09:50.480 They can indicate problems with the power, the hard drive, 214 00:09:50.679 --> 00:09:52.240 or even the network connection. 215 00:09:52.600 --> 00:09:54.559 I never really paid attention to those before. 216 00:09:54.639 --> 00:09:57.279 Yeah, they can be helpful. Now let's shift our focus 217 00:09:57.279 --> 00:10:01.519 to mobile devices. They're basically many computers these days, so 218 00:10:01.559 --> 00:10:04.799 they're not immune to their own set of quirks. Definitely 219 00:10:04.919 --> 00:10:08.759 frozen screens, app crashes, and the dreaded spinning wheel of doom. 220 00:10:08.799 --> 00:10:11.080 We've all been there. Oh yeah, But before you run 221 00:10:11.120 --> 00:10:14.120 to the nearest tech support counter, take a deep breath 222 00:10:14.159 --> 00:10:18.679 and try these simple troubleshooting steps. First and foremost, restart 223 00:10:18.679 --> 00:10:22.080 your device. It's it's amazing how many problems a simple 224 00:10:22.120 --> 00:10:24.919 reboot can solve. It's like hitting the reset button for 225 00:10:25.039 --> 00:10:26.879 your your phone's brain. 226 00:10:27.159 --> 00:10:28.320 Sometimes that's all it takes. 227 00:10:28.600 --> 00:10:30.799 If that doesn't work, try updating the app or the 228 00:10:30.799 --> 00:10:35.320 fund's operating system. Sometimes bugs or software conflicts can cause 229 00:10:35.399 --> 00:10:38.960 problems that are fixed in newer versions. Okay, what about 230 00:10:39.000 --> 00:10:42.159 when you can't hear anything. Is the speaker just not working? 231 00:10:42.320 --> 00:10:42.799 Yeah? 232 00:10:42.840 --> 00:10:46.159 Again, start with the basics. Check the volume settings. Make 233 00:10:46.159 --> 00:10:48.039 sure the volume is turned up, both for the app 234 00:10:48.080 --> 00:10:51.159 and for the phone itself. Sometimes it's that easy. If not, 235 00:10:51.320 --> 00:10:53.759 it could be a software issue, in which case deleting 236 00:10:53.799 --> 00:10:56.399 and reinstalling the app might help. And of course there's 237 00:10:56.399 --> 00:11:00.000 always the possibility of a hardware problem with the speaker itself. Okay, 238 00:11:00.879 --> 00:11:04.039 Now let's talk about GPS. We rely on GPS for navigation, 239 00:11:04.120 --> 00:11:07.440 so it's incredibly frustrating when it stops working well. First, 240 00:11:07.879 --> 00:11:11.480 make sure GPS is enabled in your phone settings. Then 241 00:11:11.840 --> 00:11:13.519 check that you have a clear view of the sky. 242 00:11:13.960 --> 00:11:17.320 As GPS signals come from satellites, you're not going to 243 00:11:17.360 --> 00:11:20.039 get a good GPS signal in a basement or a tunnel. 244 00:11:20.320 --> 00:11:21.000 That makes sense. 245 00:11:21.120 --> 00:11:24.759 Sometimes apps can interfere with GPS signals, so closing unnecessary 246 00:11:24.799 --> 00:11:27.879 apps might help. Okay, And while we're on the topic 247 00:11:27.919 --> 00:11:30.639 of things that can drain your phone's battery, let's talk 248 00:11:30.639 --> 00:11:33.240 about battery life. It seems like no matter how big 249 00:11:33.320 --> 00:11:37.679 our phone batteries get, they never seem to last long enough. 250 00:11:37.759 --> 00:11:37.879 Right. 251 00:11:38.200 --> 00:11:41.480 Often battery drain is caused by apps running in the background. 252 00:11:41.519 --> 00:11:44.879 Even when you're not using them. These battery vampires can 253 00:11:45.799 --> 00:11:47.799 can suck the life out of your phone without you 254 00:11:47.840 --> 00:11:48.799 even realizing it. 255 00:11:49.039 --> 00:11:50.200 Yeah, I've seen that happen. 256 00:11:50.360 --> 00:11:53.039 To combat this, check your phone's settings to see which 257 00:11:53.080 --> 00:11:55.519 apps are using the most battery. You can then close 258 00:11:55.600 --> 00:11:58.879 or restrict those apps to conserve power. Turning off features 259 00:11:58.919 --> 00:12:01.279 like Wi Fi and blue when you don't need them 260 00:12:01.320 --> 00:12:04.039 can also make a big difference. And speaking of batteries, 261 00:12:04.080 --> 00:12:06.960 there's one serious issue that we need to address swelling. 262 00:12:07.519 --> 00:12:10.279 A swollen battery is a sign of a faulty battery 263 00:12:10.320 --> 00:12:14.159 and needs to be replaced immediately. Do not try to 264 00:12:14.200 --> 00:12:17.080 open or puncture the battery, as this could cause a fire. 265 00:12:17.840 --> 00:12:20.519 Oh wow, So if you notice any bulging or deformation 266 00:12:20.639 --> 00:12:24.440 in your phone's battery, take it to a qualified technician 267 00:12:24.519 --> 00:12:24.960 right away. 268 00:12:25.159 --> 00:12:25.600 Good to know. 269 00:12:26.159 --> 00:12:28.519 Now, we've covered a lot of trible shooting tips for 270 00:12:28.679 --> 00:12:31.240 laptops and mobile devices, but sometimes you need to take 271 00:12:31.279 --> 00:12:34.559 things a step further and actually disassemble your device to 272 00:12:34.600 --> 00:12:36.799 fix a problem or upgrade a component. 273 00:12:37.120 --> 00:12:38.559 Yeah, that's a bit more advanced. 274 00:12:38.799 --> 00:12:41.039 This is where things can get a bit more complicated, 275 00:12:41.120 --> 00:12:44.399 but with the right information and tools, you can tackle 276 00:12:44.480 --> 00:12:48.000 some basic repairs yourself. But before you grab your screwdriver 277 00:12:48.120 --> 00:12:50.279 and start taking things apart, there are a few things 278 00:12:50.360 --> 00:12:54.399 you need to know first and foremost, Documentation is key 279 00:12:54.600 --> 00:12:57.840 before you touch a single screw. Find a good guide 280 00:12:57.919 --> 00:13:01.080 or video. Online websites like I fix it are great 281 00:13:01.159 --> 00:13:05.320 resources for step by step instructions and helpful tips. It's 282 00:13:05.360 --> 00:13:08.159 like having a digital roadmap to guide you through the 283 00:13:08.200 --> 00:13:10.519 maze of circuits and components inside your device. 284 00:13:10.600 --> 00:13:11.159 That's helpful. 285 00:13:11.240 --> 00:13:13.159 While you're at it, Grab a pen and paper or 286 00:13:13.200 --> 00:13:16.120 your phone to take notes and label each part as 287 00:13:16.200 --> 00:13:18.480 you remove it. Trust me, you'll thank yourself later when 288 00:13:18.519 --> 00:13:21.080 it's time to put everything back together. It's a lot 289 00:13:21.120 --> 00:13:23.559 easier to take something apart than it is to reassemble it, 290 00:13:23.600 --> 00:13:28.120 so being organized is crucial right. Next up tools. A 291 00:13:28.159 --> 00:13:31.039 good set of small screwdrivers is essential, as well as 292 00:13:31.039 --> 00:13:34.279 a pair of tweezers for those tiny connectors. And don't 293 00:13:34.320 --> 00:13:37.000 forget a magnetic mat or tray to keep all those 294 00:13:37.039 --> 00:13:39.799 screws from rolling away. I can't tell you how many 295 00:13:39.799 --> 00:13:41.279 times I've lost a tiny screw. 296 00:13:41.080 --> 00:13:42.480 In the carpet. Oh yeah, I've been there. 297 00:13:42.720 --> 00:13:47.000 Now a word of caution, be gentle. Laptop and mobile 298 00:13:47.039 --> 00:13:50.799 device components are delicate, so use a light touch and 299 00:13:50.840 --> 00:13:54.759 avoid forcing anything. If something feels stuck, don't try to 300 00:13:54.799 --> 00:13:57.559 muscle your way through it. Refer back to your documentation 301 00:13:57.759 --> 00:14:00.840 or consult an expert. Disassembly is not for the faint 302 00:14:00.840 --> 00:14:01.200 of heart. 303 00:14:01.440 --> 00:14:03.600 It sounds a little scary, but if. 304 00:14:03.480 --> 00:14:07.039 You're patient and methodical, you can accomplish a lot. And remember, 305 00:14:07.039 --> 00:14:09.759 the more you learn about how your devices work, the 306 00:14:10.519 --> 00:14:13.279 better equipped you'll be to troublesheet problems and keep them 307 00:14:13.360 --> 00:14:14.080 running smoothly. 308 00:14:14.279 --> 00:14:15.000 That's good vice. 309 00:14:15.519 --> 00:14:19.639 So far, we've focused on troubleshooting individual devices, But what 310 00:14:19.720 --> 00:14:22.759 about when the problem is with your network. Nothing is 311 00:14:22.759 --> 00:14:25.919 more frustrating than when your Internet connection goes down and 312 00:14:26.000 --> 00:14:29.000 you can't figure out why. Yeah, network problems can be 313 00:14:29.039 --> 00:14:32.080 tricky to diagnose, but there are some common things to 314 00:14:32.120 --> 00:14:34.639 check that can often get you back online in no time. 315 00:14:34.879 --> 00:14:37.080 It's like a checklist for when the Internet decides to 316 00:14:37.080 --> 00:14:39.720 take a break. And like we talked about with devices, 317 00:14:39.759 --> 00:14:43.600 sometimes the simplest solution is the right one. So let's 318 00:14:43.639 --> 00:14:46.679 start with the basics. Is your router plugged in? Is 319 00:14:46.720 --> 00:14:49.440 the Wi Fi turned on? You'd be surprised how often 320 00:14:49.480 --> 00:14:51.559 these simple checks can resolve the issue. 321 00:14:51.720 --> 00:14:53.000 I'm guilty of that myself. 322 00:14:53.120 --> 00:14:55.840 Sometimes I overthink things when the solution is staring me 323 00:14:55.960 --> 00:14:56.679 right in the face. 324 00:14:56.919 --> 00:14:57.559 We all do it. 325 00:14:57.960 --> 00:15:01.240 But if if those basic checks don't fix the problem, 326 00:15:01.440 --> 00:15:04.480 then it's time to dig a little deeper. The next 327 00:15:04.480 --> 00:15:07.679 step is to check the cables and connections. Make sure 328 00:15:07.720 --> 00:15:10.240 everything is securely plugged in and that there are no 329 00:15:10.399 --> 00:15:14.159 loose or damaged cables. Sometimes it's literally just a matter 330 00:15:14.200 --> 00:15:17.000 of wiggling a wire or plugging it in more firmly. 331 00:15:16.679 --> 00:15:19.919 Because sometimes it's the physical connections that cause the most headaches. 332 00:15:20.200 --> 00:15:23.519 Absolutely, and if you're still having problems, try restarting the 333 00:15:23.600 --> 00:15:27.360 router and your device. It's amazing how often a good 334 00:15:27.399 --> 00:15:28.840 reboot can fix things. 335 00:15:28.919 --> 00:15:32.240 That's like hitting the reset button for your entire network exactly. 336 00:15:32.559 --> 00:15:34.200 Now, if you've tried all of that and you're still 337 00:15:34.240 --> 00:15:36.600 having trouble, it's time to get a little more technical. 338 00:15:37.120 --> 00:15:39.720 Check the IP address on your device. If it starts 339 00:15:39.720 --> 00:15:42.159 with one sixty nine point two five four, it means 340 00:15:42.159 --> 00:15:45.679 your device isn't getting a valid IP address from the router. 341 00:15:45.799 --> 00:15:47.519 Okay, now you're starting to lose me. What's an IP 342 00:15:47.600 --> 00:15:48.200 address again? 343 00:15:48.360 --> 00:15:51.279 Remember we talked about IP addresses earlier. It's like the 344 00:15:51.320 --> 00:15:54.519 street address for your device on the Internet. Every device 345 00:15:54.559 --> 00:15:57.639 that connects to a network needs a unique IP address. 346 00:15:57.360 --> 00:15:59.120 Right I remember. So if my device isn't getting a 347 00:15:59.159 --> 00:16:01.720 valid IP address, that means it can't communicate with the. 348 00:16:01.679 --> 00:16:06.759 Network exactly, and this could indicate a problem with the DHCP. 349 00:16:06.200 --> 00:16:08.000 Server DHDVP server. 350 00:16:08.080 --> 00:16:11.279 That sounds intimidating, It's not as scary as it sounds. 351 00:16:11.320 --> 00:16:16.039 The DHDP server is essentially a service that automatically assigns 352 00:16:16.159 --> 00:16:19.960 IP addresses to devices on the network. So if the 353 00:16:20.039 --> 00:16:22.639 DHDP server is down, your device won't be able to 354 00:16:22.639 --> 00:16:24.679 get an IP address and connect to the Internet. 355 00:16:24.799 --> 00:16:27.240 So it's like the network's traffic cop making sure every 356 00:16:27.240 --> 00:16:28.320 device knows where to go. 357 00:16:28.600 --> 00:16:31.960 That's a great analogy. And if restarting the router doesn't 358 00:16:32.000 --> 00:16:36.159 fix the DHCP server issue, you might need to contact 359 00:16:36.159 --> 00:16:39.639 your Internet service provider for help. They can usually troubleshoot 360 00:16:39.679 --> 00:16:42.840 the problem remotely or send a technician out to fix it. 361 00:16:42.919 --> 00:16:43.840 Okay, that makes sense. 362 00:16:44.000 --> 00:16:48.200 Now, what about slow internet speeds. That's a problem I've 363 00:16:48.200 --> 00:16:51.799 definitely experienced before and it's incredibly frustrating. 364 00:16:51.879 --> 00:16:52.879 Oh yeah, tell me about it. 365 00:16:53.320 --> 00:16:55.559 Slow speeds can be caused by a number of things, 366 00:16:55.759 --> 00:17:00.559 from router congestion and signal interference to problems with your 367 00:17:00.559 --> 00:17:04.160 Internet service provider. One thing you can try is is 368 00:17:04.279 --> 00:17:07.279 checking the speed and duplex settings on your network adapter. 369 00:17:07.640 --> 00:17:09.640 Speed and duplex those are new ones. 370 00:17:09.799 --> 00:17:12.799 Speed refers to the rate at which data is transferred, 371 00:17:12.880 --> 00:17:15.279 and duplex refers to whether data can be sent and 372 00:17:15.319 --> 00:17:16.759 received simultaneously. 373 00:17:16.880 --> 00:17:19.519 So if the speed and duplex settings or mismatch between 374 00:17:19.519 --> 00:17:22.599 my device and the router, that could slow things down. 375 00:17:22.839 --> 00:17:26.039 Exactly. It's like trying to have a conversation with someone 376 00:17:26.039 --> 00:17:28.279 who's speaking a different language at a different pace. 377 00:17:28.559 --> 00:17:30.759 I get it. So how do I check those settings? 378 00:17:31.000 --> 00:17:33.680 It depends on your operating system, but you can usually 379 00:17:33.720 --> 00:17:36.880 find them in the network settings or adapter properties. 380 00:17:36.960 --> 00:17:38.519 Okay, we'll have to look into that. Now. 381 00:17:38.519 --> 00:17:41.759 What about wireless signal issues. I've definitely had my fair 382 00:17:41.759 --> 00:17:45.319 share of those. You know, the dreaded dead zones where 383 00:17:45.319 --> 00:17:47.079 the Wi Fi signal just disappears. 384 00:17:47.440 --> 00:17:48.039 I know those well. 385 00:17:48.319 --> 00:17:52.079 Wireless problems are often caused by interference from other devices 386 00:17:52.359 --> 00:17:56.279 or or by being too far from the router. If possible, 387 00:17:56.400 --> 00:17:59.759 try try moving closer to the router or or removing 388 00:17:59.759 --> 00:18:02.200 any obstacles that might be blocking the signal. 389 00:18:02.359 --> 00:18:05.240 So no hiding the router in a closet or behind 390 00:18:05.240 --> 00:18:06.519 a stack of books. 391 00:18:06.319 --> 00:18:08.359 It's best to keep it out in the open and 392 00:18:08.720 --> 00:18:10.960 as close to the center of your house as possible. 393 00:18:11.079 --> 00:18:13.920 That way, the signal can reach as many devices as possible. 394 00:18:14.079 --> 00:18:14.480 Good to know. 395 00:18:14.759 --> 00:18:17.160 And what about when you can't even see your network's 396 00:18:17.240 --> 00:18:19.839 name in the list of available Wi Fi networks? 397 00:18:19.880 --> 00:18:20.480 Oh? Right? 398 00:18:20.720 --> 00:18:22.960 That could mean the router is out of range or 399 00:18:22.960 --> 00:18:25.559 that the network name also known as the SSID, is 400 00:18:26.000 --> 00:18:27.440 hidden for security reasons. 401 00:18:27.640 --> 00:18:29.319
