I am helping my neighbor with a problem with his Uverse service. The internet service worked fine for almost a year on a desktop that uses home networking via the electrical wires to access the residential gateway/router (RG). A few weeks ago the desktop could not be assigned an IP address by the RG. The desktop finally had to be manually assigned an IP address to get it to connect to the RG. Whether the home networking or wireless card is used on this PC it now says that there is a connection, but when you open Internet Explorer you get the message that the web page cannot be displayed. Is it possible that there is no connection to the RG even though it says there is? If that is not possible then what could cause this problem with IE not accessing the internet. FWIW, I tried to access several different web sites with no luck. Also, once the connection to the RG was supposedly established the Uverse technical support folks said they could not assist with the IE problem. No surprise there. I would appreciate any suggestions on the IE problem. TIA.
