Hello, SEOULiAN. I'm your subscriber, and I major in data security. I want to ask you about old terminal boxes because I don't understand their parts. In my Living Room 2, I have an SK WiFi router and I think there's a network between Living Room 2 and a small room right next to the gate. The main wire is connected to the main room. What should I do to get WiFi in the small room? I'd also like to know whether I need a router, thanks. From your biggest subscriber.
So that's the email I got. I'll tell you what to do with terminal boxes like this. Hello, I'm SEOULiAN. Many subscribers ask me about their home networks. I answered some of your answers but I'm sorry I couldn't answer all of them. One of the repeated questions was about terminal boxes that look like this. Many had no idea what to do with them. They have so many wires that looks formidable. They look like something in the movies about bomb squads as if one broken wire would cut of all electricity. It looks exactly like that. But it's actually really simple. I got the whole thing so I'll explain the structure and how it operates and what you need to do to build your home network. First, a block that looks like this is called a one-ten block, or a 110 block. I'll call it a one-ten block. Because there are so many wires you might be scared, but don't be. This is how it looks before you install the 110 block. You put blocks on top of this to make the thing you see inside your terminal box. When your house is under construction you need to connect ethernet ports in each room to the ethernet junction box. The cable wires from each room are connected to the bottom part of the 110 block. If you look at the bottom part of your block you can see the cable goes in, and its wires are laced on the bottom part. If you attach this block on the top the metallic part clips the wires and gets connected. If you put wires on top of the blocks they automatically get connected to the cable on the bottom. So, the 110 block is to connect your rooms to the junction box and to extend your wires. It's only for that. So what I recommend is for each of the rooms connected to your 110 block use the RJ45 cable. 110 block doesn't really serve a big purpose so it's okay if you remove it. But I don't recommend removing the pre-installed ethernet cables. Many beginners make mistakes trying to make a cable using RJ45 connectors. Then you have to keep cutting the original cables and in the worst case scenario, the original cables would become too short to do anything. I recommend connecting the cables on top of the 110 block. But buying all the tools to make LAN cables just to attach LAN cables on this would be too much. 1 meter of CAT.6 LAN cable costs about 1,500 won on the internet. Buy this and cut it in half to make a cable for connecting two rooms. Buy as much cable as you need and you only need a wire stripper. It costs only about 1,000 won. These are all you need. First, remove all the wires on top of your block. You can easily take them out by lifting them. Next, take eight wires from the cable cut in half. On each of the four colors on your 110 block connect each wire by color. You can see they're color-coded. The order is blue, orange, green, and brown. You don't have to memorize the order but just remember, the striped ones go first. Use the front part of your cable stripper to push the wires into the 110 block. Then, your 110 block has all the RJ45 connectors connected to your room. The rest is exactly the same as my previous video about home network configuration. Let's do a case study based on the email I received. Looking at the 110 block I can see it's connected to seven rooms. Then you need four, 1m-long LAN cables cut in half. That makes 8, so you only need to buy 4. After the wiring job you'd have cables with RJ45 connectors for each room. Let's make this and get started. The main wire is the cable that receives data. Usually, we write "Data in" or D.in." But if your room has no name but something written then it's probably the cable where the data goes in. Use a cable coupler on your main wire to send it to Living Room 1 directly. And then, on the wall port in your Living Room 1 use a cable to connect it to the WAN port on your router. Now, your router can receive data. Next, plug a LAN cable to your router's 1st LAN port and connect it to the wall port in your Living Room 2. Then, your router's internet went through the Living Room 2's cable to arrive at the terminal box. Now, get a hub ready for your terminal box. You can connect as many rooms as you want but a 5 pin hub is probably enough for you. Plug the cable from Living Room 2 to the hub and now your hub is ready to share the internet. Next, on the remaining ports on your hub connect all the rooms where you want the internet. Entrance room, main room, small room, even the kitchen telephone if you don't use the phone. Now, all the internet ports in your room are connected to the internet by wire. All the devices connected to the port are under the internet router in your Living Room 1 so now you have a home network. Now, you have no reason to be scared of complicated cables. What's important about the 110 block is the one cable connected to each room on the bottom part. That's not something we'd have a reason to touch and there's nothing to change. You can be confident in removing the complicated wires on the top and change them to the RJ45 version which looks more intuitive and add a hub to easily make your home network. In this video, we talked about the 110 block in your terminal box and did a case study. Check out more definitions about the home network in this video and please comment or email me if you have any questions. I'll try my best to reply and if there are many similar questions, I'll make a video like this. See you in my next video. Bye! The End! When you send me an email, try to be as detailed as possible. If you don't, it's hard for me to understand what's going on. It's even better if you send me a picture so please take that into account when you email me a question.
