Yes, I came from qwest service where I had this wireless router setup. I moved to comcast service and they gave me a RCA (Thomson) modem. i can only hook up one computer at a time. I want to use the 2wire 270 to set up a wireless system. I hook it to the modem and my computers say it is connected with an excellent signal, but no pages will load. I've turned off all firewalls, virus scanners, etc. What am I doing wrong? Any help would be appreciated. ...
