I know it is not a problem with my router as I havE other devices on the network and they work fine. I have tried updating and reinstalling all drivers, updated bios, changed the power management settings. I also read that in some network card the Bluetooth causes problems so I even disabled Bluetooth via device manager but still the problem occurs. It doesn't occur frequently but maybe once every 5-6hrs.(no fixed interval, sometimes it happens just after switching on)
