Ethernet adapter is acting crazy

The ethernet adapter in a computer I'm setting up is having some weird issues. It disappears from the Control Panel\Network and Internet\Network Connections every time I restart the computer. However, when I open Device manager, I do see the adapter name with a yellow exclamation mark. If I click on "properties" it says "this device cannot start (code 10)". I disable it, enable it again, and then ehternet works perfectly, no problems at all.

I have installed the latest driver from Intel, and the adapter always starts working as soon as I install the driver, but then disappears again every time I restart the computer with the behavior stated in the above paragraph. The computer is an HP 8200 elite AIO.

Which version & edition of Windows is this happening on?

John

Try an external USB adapter. It that works, the on-board adapter is defective.

It is Windows 7 on an HP 8200 elite AIO. Once I re-enable the adapter, it works perfectly though (in fact I'm typing right now from the same computer) so I really doubt it's a defective adapter. Seems more like a software issue to me.

Also, the latest driver I downloaded and installed from Intel is version 22.x, but when I check out the information in the device manager it says driver version 12.15.31.4.

Try System File Checker (SFC /SCANNOW) and if that does not resolve it, try a Windows 7 Repair Install with the Windows 7 DVD

It claimed it repaired some files but couldn't repair others, and created a CBS log with info on what it did. At this point I suspect it might be just a bad image of another machine. Thanks for your help.

I could be a bad image.

Also try a Windows 7 Repair Install. Here is a Seven Forums Tutorial to assist.
