I have two routers, a first one where i connect directly my computer via cable, and a second one that i use to broadcast the internet connection to another room (somehow its more powerful and it will send my connection over 40 meters distances unlike my first router). Anyway. When i have only my first router connected i do have a good internet connection, but when i connect the second one, the whole connection fails.
I dont know wether this is an IP conflict (there isn't such message on my Operating System, Windows 7) or any other thing, but i really dont understand.
I can make a video for better understanding, i dont know if the second or first routers have been reset (it might be possible, but i dont know),as i have worked for months flawlessly with both routers, one connected to another, after receiving advice in this other question:
