I recently bought a HP touch smart running windows 7. At random times, internet connectivity is lost while the wireless signal remains strong. The only way to restore connectivity is to restart the PC. Nothing else works. Have many other PC's on the same router also running windows 7 and no problems there. Have changed routers and problem remains. I have reinstalled the network drivers with no help. Any thoughts?

Take your laptop in for servicing. It sounds as if you have a bad wireless card.
