In the Adapater Settings, it says that the Wifi is offline and there's a red X on it. When I go in ipconfig/all, the assigned IP is a private IP, starting with 169.254.x.x. There's no default gateway assigned. Obviously, the computer isn't able to get an IP from the routeur/modem, but I don't know why.
I'm going to install Windows 7 later this afternoon, and reinstall the Wifi Adapter drivers (I was using the latest for W8 x64 from the manufacturer website) and see how it goes. I wish I had another wifi adapter to test. =/
I'm seriously considering powerline adapters, the computer I'm using is right above the modem, one level above though. It would be a pain to dig a hole in the floor to route the ethernet cable. However, if I'm using a powerline adapter, it would probably work fine, but I don't know.
Any solutions guys?
Thanks all for helping!
