I have installed the above router at my home. The problem is that when i connect it my cordless phone stops working. The line is constantly busy. I have tried another cordless phone and it still happens. I have tried a corded phone and that works fine. I have also tried disabling the wireless and the problem still occurs. It works fine with a usb modem. I just wondered if anyone else has had the same problem before i go out and buy a new router and get the same problem. any help will be gratefully appreciated.
