Waking or booting, Win7 doesn't recognize network adapter

by andrewrg / July 22, 2011 11:03 PM PDT

I have a desktop computer that I built. I have a TP-LINK PCI wireless adapter and I'm running Windows 7 SP 1. SOMETIMES, when I boot the computer or wake it from S3 sleep, Windows does not recognize the network adapter. It's not listed in the device manager. Shutting down the computer and flipping the switch on the power supply to cut power to the motherboard, then powering up again, the computer will recognize the network adapter without a problem.
What confuses me is why this only happens SOMETIMES. Sometimes when I wake or boot, there is no problem.

Motherboard:ECS P67H2-A2 SLI (B3) R
Processor: INTEL CORE I7 2600 Sandy Bridge 3.4G
Network Adapter: TP-LINK TL-WN851N

Be sure you installed the motherboard drivers (do not use Microsoft drivers or it's driver check buttons.)

If it fails, ask the supplier what parts they want to exchange.

I'd arrange for return as defective.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
