After months of normal operation, this morning my wireless connection failed. Two other computers in the same room work fine. I manually re-entered the IP address (when "repair" didn't work); desk tray icon indicates "connected / signal strength excellent" - but when I try to access internet or email, no luck... it's as if I am not connected.

Nearly new Toshiba laptop, internal wireless card; don;t know what brand.
I'm barely wireless literate -- tried everything I knew to try. Help most welcome!
