Problem connecting wired computer to Clear internet - can someone help?

We have three computers at home – two wireless, one wired. We just got Clear internet yesterday. The two wireless computers and the PS3 are connecting to browsers (Explorer and and Firefox), but the wired one will not connect to the browsers.

The wired computer is wired as following: From the Clear modem to the Clear voice router – for the phone, to our wireless-g router and into the PC. The chat program Skype is connecting to the internet on the wired computer, but the internet browsers are not, nor can the virus software connect to the online database.

Clearly, it’s not as simple as a connection problem. If it was the connection, the wireless computers and PS3 wouldn’t be connecting to the browsers, and Skype wouldn’t be connecting, either.

Does anyone know what is going on? Talked to Clear tech support and the guy just had us power cycle the modem and router, which we tried both last night and today. What gives???
