Returning from a 3-week vacation, during which my desktop was off, my local internet connection would no longer come active when it came out of hibernation. The wireless functioned, but the local connection would not work unless
I physically unplugged the cable from the router (Netgear) and reinserted it.
After several days of frustration I went into Device Manager, unchecked the ethernet adapter option "allow the computer to turn off this device".
This seems to have cleared up the problem, at least so far...
Thanks. I did not know where to fin "Ethernet adapter option"; so, I selected Network adapters, which showed me 5: Intel(R) Centrino(R) WiMAX 6150,
Intel(R) Centrino(R) Wireless-N 6150,
Microsoft Virtual WiFi Miniport Adapter,
Microsoft Virtual WiFi Miniport Adapter #2,
Realtek PCI GBE Family Controller
So, I selected one at a time and all but the first had a Power management tab which had the "Allow the computer to turn off this device to save power" check box checked. I unchecked each and am hoping it will solve my issue.
Thank you again for sharing your experience.
