On my wired PC, that is connected to the router, after 5-6 hours the internet is disconnecting. It says: Network cable unplugged. So I have to shut down my pc, then turn on again. All mobiles connected to the WiFi work well. Also I have unchecked "Allow the computer do turn off this device to save power", but nothing. In device manager says this message "This device cannot start. (Code 10)".

Modem : Cisco EPC2202
Router : TP-Link TL-WR740N
LAN Card : Gembird NIC-GX1 (I bought it 3 months ago)

I tried to change the connection to USB (instead of Ethernet cable), and everything works fine but internet speed is reduced.

Please help this happens already 2 months.
