Thanks for your help in advance! I just bought a WRT54GS router to go along with cable internet run through a 'surfboard' modem. The router worked for a few hours then I was disconnected and was unable to reconnect. The message that kept coming up was something along the lines of 'you were unable to establish a certificate to connect to the wireless internet' and I was unable to acquire a network address. I have set up wireless networks before, I'm no expert but I can handle the general stuff. I have never encountered this problem before. I have enabled security but that shouldn't be an issue. Does anyone have any knowledge of how to fix this? Thanks!
