I have a Motorola SBV5120 SURFboard cablemodem and I´ve never experience any problems connecting to Internet. But I tried to use a Tenda W541R router and I can´t access the Internet. My Internet provider support service said there´s no problem with the modem (I still can connect if I use it alone), but I can make the router connect in anyway. I can enter the router settings (using http://192.168.0.1) but it doesn´t detect the modem. I have dinamic IP, but seems the router can´t find it. Do I have to set something in Windows 7 in order to make my router "see" the modem´s connection?
