I have an HP laptop and cannot connect wirelessly at home. Elsewhere i can. My cable modem is followed by a linksys Wrt54gs, and my computer says i am connected with an excellent signal. I have repaired the connection, upgraded the firmware in the router, checked settings as best I know how, buy each time i try to connect to the internet, I get the message "Internet Explorer cannot display this webpage" no matter what webpage i try to open. Does anyone know how to remedy this?
