I have 2 d-link modems a 2320 and a 520 both with some sort of issue. According to the user manual I should be able to login to either one by typing 192.168.1.1 into the browser. The login in page does not appear instead giving something like a "time out" message yet both of them work. when connected. At one time the login screen was working but now...? I have no idea why.
