Using a wireless card adapter to connect to my att uverse. This laptop has never been connected to it,but was online when i had plain high speed service. I have tried the command mode and can get the ipconfig/all,put in the ip address,but when I put in the gateway address it comes back as sent but lost. When i try to open ie it relects page unavailable. My laptop says I am connected with the appropriate icon/strength. ATT checked my servicce and it is functioning,as I am on the desktop now. Suggestions please.
