You can try the IP 192.168.0.1.Updated to the latest firmware will also cause the IP change. The best way is to check the computer's Default gateway by do Ipconfig/all in the cmd window

My computer is the only device connected to the router, with and ethernet cable. I've tried Firefox, Chrome and IE9 and i also tryed without wifi on. In fact, i borrowed the same router to a friend and it works perfectly doing the same connection, so the problem is in the router and not in my pc. Please help me, i dont know what to do, sounds like an internal problem, but i did every reset type i could and the thing works just for 15 seconds. Of course i checked if the ip is 192.168.1.1 or 192.168.0.1, the router is using 1.1 as expected, but after the 15 seconds it doesnt respond any more.
Thanks, wait for an answer

It seems the hardware problem for the router after the update. It shows quite unstable and there is no response by reset on the router. No idea now expect the hardware problem.
