I have Toshiba Qosmio Q60 and I recently update with Windows 8. It was working all fine and suddenly it stops connecting to internet on Wi-Fi. The exact problem is as below:
1. Connect to router and internet on LAN ( Ethernet connection).
2. Connect to router on Wi-Fi. I can configure my router on Wi-Fi and every thing is fine.
3. No internet is available if connected to Wi-Fi.
