How do you setup lan?

[WhatComesAround]

Ok, so I am a complete noob when it comes to networking, all I know is Ethernet cable comes from the wall, magic happens, and we have wifi. Today I am trying to setup lan networking. I have like this lan thing throughout the house (that thing in the wall that is everywhere, when I said noob I meant it). I have connected a cat5e cable to the router and connected the other end to the wall thing, the light on the router for LAN 1 does not turn on, then I connected it to my pc, nothing happened. Btw i plugged the blue Ethernet cable into the blue router socket thing and the lan cable into the yellow socket thing. Can anyone help me? Thanks a lot in advance

I want to know this too. I know how to do it over wifi though, if you want to know.

I got that part figured out though, hope someone can help the both of us

Nice, really useful at school btw.

can you send me a picture of your router. the place where you connect the cables? the color coding are different for most routers

 

and you can use a network switch and connect each other up. but it need electricity but its good and they are usally cheap. unless you buy a 48 port switch

just connect 1 cable to the switch and the rest wherever you want. it  doesnt matter

*the picture*

 

the blue one is the WAN side, which is where your internet is going in and blocks traffic that tries to walk in without permission

the yellow is the LAN side, where you must use the LAN side to connect to the internet. or else you will be spammed with junks. trust me i have tried to leave it on for a month as a school project. lots of porn and viruses.

 

hope i was understand able

So I what I did there was correct right, but when I connect it the lan cable to the socket in the wall, and then use another socket elsewhere to connect to a computer I cannot connect to the internet

yea the cable in the wall needs to be crossover cable i think, unless the router has auto mdix which automaticly adjusts the input and output. some new computers does have it. some routers have it too i think. network switches usually have it.

 

im not so good on ethernet cable but i know you cant connect PC to PC with straight through ethernet cable. you need crossover.

but do you have internet if you connect directly to the router with the PC? without going through the wall socket?

Most likely all of your wall jacks run to a central point, an MDF or patch panel. This then allows you to cross connect different jacks, or plug them all into a switch at that location to make them all work. 

 

 

 

This is an example patch panel. 

 

Crossover cables are not as big of a deal as auto MDI/MDX is extremely common anymore. However it is something to keep in mind.

My setup goes from the modem (source of internet) into the WAN port on the router (basically the "internet" jack) and other devices connect to the router's LAN ports (basically the "splitter" to connect various things to the internet and the router configures devices plugged into it) and instead of using these four ports, Inhave one of those ports going to a network switch, and everything is connected there. Are you sure the ethernet in your house is properly labled and terminated? you need to figure out where the other end of the cable that your PC is connected to is terminated

As above each "room socket/s" should all come back to one central place.

Not sure if most trashy home routers have auto MDIX lol. I have no idea why someone who has 0 knowledge of networking would have a crossover cable in his house? He should have all straight throughs most likely? You only need a crossover cable to communicate between like devices, such as between a router & a router or a PC & a PC. I'm not seeing the problem here. Outside from modem to WAN port on router. Connect his PC via one of the LAN ports on the router, what's not working?
