adapter is listed as properly functioning in Device Manager, open a command prompt and Ping, localhost or 127.0.0.1. If the Ping fails, reset TCP/IP by entering, netsh int ip reset resetlog.txt.
Both wireless and eathernet cable. Using modem ok now with other laptop. Self diagnosis and tech at telco seems to indicate a problem within laptop. Couple of things came up: "Error TCP/IP adapter binding" and "TCP/IP not connected". Tech asked if I hit a keyboard key that shut it down. They referred me to Toshiba. I think I tried all the "Control Panel..Internet Connection" stuff.
XP Home, SP2.
Any help please.
