We bought my son a new Sony laptop. We then got him a wireless card from Verizon. When he is at a friends house that has wireless he can access the web with no problem. But when he is at home using the verizon card he cannot. The card says he has internet connection but he cannot open web pages. When he tries to open messenger it say "invalid IP address". But when looking at the properties it list an IP address and it is not a 169. address. Does anyone have any suggestions about what to do next short of giving up and returning the card. We took it to Best Buy and all they did was check to see if it was connected and that the computer was working and guess what... it was connected and the computer is working properly. I don't know what else to do, is there something in the settings that needs to change. HELP! OH if it helps it is running Vista.
