After updating to Windows 8.1 my LAN connection keeps dropping and the adapter sometimes disables by itself.
I always get "Limited" connection notification after using it for a short period of time. This problem goes away once, I reboot the system but it's very annoying.
I am not sure what went wrong because it was perfectly alright with Windows 8. They must have broke something...
