Windows 10: Unknown Network

I continue to get the "Unknown Network" when trying to set up my Ethernet controller. I am using my WiFi to access the internet but the direct connection through the hard cable is a lot faster when it's working. I have disabled it. I have removed it. Cleared the IPv4 and 6 logs, but continue to get this message. It drove me to replace my router. Any suggestions?

Unknown networks

I have no 'forget' option. They are not known networks, so I can't manage them. They are listed when I select which network of mine I want to connect to, but there are 8-10 unknown networks that aren't mine. They are all checked with 'connect automatically'.
How can I remove these unknown networks from my list?

 

Network devices listed under Unknown in Device Manager


I have a Dell Inspiron M731R laptop upgraded from Windows 8.1 to Windows 10 Home 64-Bit that suddenly quit connecting to the home network. Was using wireless, so switched to an Ethernet cable, but still no luck. I just discovered that ALL of the network-related devices are now listed under an "Unknown" tab in the Device Manager. A check of properties of each item in that folder says they are all working properly, but that obviously isn't the case. I tried uninstalling each of the 4 items, but when they are recognized again they still show up under the Unknown tab. Any suggestions would be welcome.

 

unknown network connected

I HOPE SOMEONE CAN HELP ME I RECENTLY DETECTED AN UNKNOWN NETWORK CONNECTED AND UNDER SETTINGS IT IS LISTED AS FRONTIER4169 THE PERFERRED CHOICE THEN MY NETWORK IS LISTED. WHAT IS IT AND WHERE DID IT COME FROM?
