Nice one Rob. Looks to me its your routers wireless settings. If you can access your router, change the SSID and password, use WPA2 if possible. Turn your pc OFF, reboot your router by unplugging it, wait 30 seconds and reconnect, wait till all lights show. While this is being done, go to Manage Wireless Networks, right click NPK38 and delete it, reboot netbook, enter new password and Pray.
