Missing network adapter, but device manager OK
Hi all. A very weird problem just happens to my desktop, I hope anyone could help me to avoid a complete reinstall.
It was working fine, I didn't install or change nothing (mostly is used as MediaCenter). It was working perfectly without any change for months. Then I shutdown one day as always, and when I reboot the next day no network is present.
The PC is an Acer Aspire X3900 desktop with an integrated intel NIC. This is what I have seen:
This is what I had already try:
I still have not any network adapter present in windows network configuration panel, or listed with IPCONFIG. I think some windows network component must be damaged, but that is beyond my Windows 7 knoledge.
Thanks a lot in advance.

Network adapters sometimes fail. It may be due to some electrical disturbance which induces a surge in the cable, which knocks out a component in the NIC, but the rest of the card thinks it is working properly. A diode or capacitor failure perhaps.
Google USB Ethernet adaptor. Prices start less than £10 UK.
Try a replacement for the card - it won't break the bank. I assume that you would need a USB connection? It doesn't even have to be an exact replacement - any recognized mainstream brand of the right specifications should do. Just take a note of the MAC address of the old card - ipconfig /all from the command prompt, and note the physical address. It may be important for your broadband connection. You may need to disable the onboard NIC in the bios.
