yeah that's correct.. sometimes the wireless channel has to be change as well . 1 - 6 - 11 i think  are the channels that don't overlap. you can access GUI or your modem by typing 192.168.1.254 on your URL. (if you want to do it yourself) or might as well call tech support and ask them to change it. and see if that will work..

oops! restart your computer after changing the wireless channel : )
