Windows 7 - Unidentified Network on Ethernet - Wifi works fine
I have a Win 7 system. Everything was working, until a few days ago, and then the Ethernet connection stopped. The activity LEDs work, but the Ethernet will not connect. The Wifi works fine through the same router as the Ethernet is plugged into.
Here is what I did so far.
- Rebooted PC (full power cycle)
- Rebooted router
- MSCONFIG to disable all unknown services and apps
- Replaced Ethernet cable
- Tried a different port
- Confirmed Ethernet driver is latest version
- Deleted Ethernet driver anyway and reinstalled
- Reset IP Stack
- Set TCP/IPv4 to static IP and defined the DNS server
- Confirmed the adapter's advanced settings were correct
- Connected to a USB Ethernet adapter that I know works (and has worked before on this PC)
Nothing I did in the above list worked - Ethernet does not connect. The activity LEDs are working. The Network Connections shows a plugged-in Ethernet as an Unidentified Network.
Here is the IPCONFIG/ALL
I am a total loss. I thought it was a hardware problem at first, but the fact that it does not work on a USB Ethernet adapter tells me the problem lies somewhere in Windows.Windows IP Configuration
