i have a toshiba laptop with windows xp. i used it on vacation with a wireless connection and it worked fine. however when i use it at home with a cable modem, it will connect online. but after about 15 minutes when i change websites i get the web page cannot be displayed.....diagnose connection problem...or web site is unavailable message. even if i close it it will not reconnect until i restart the computer. any suggestions?
thanks
