I just pass a 75 feet ethernet cable from the router (WBR-2310) to my room with my new computer that has windows 7 installed. The router is wired or wireless. The computer connect to it with a usb wireless adapter but when I connect it with the wire, it doesn't work. I already try the hard reset and I also try to connect the same wire to my laptop and it works but the laptop has windows XP.
I'm pretty sure it is something in the settings of my win 7 but I don't know where to go, i'm new with the OS. And I already check for compatibilty with win 7 at microsoft and it's ok.
