Windows 10: 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 devices connected to my pc

It is found under network connection, listed as unknown devices connected to my pc. After changing password to FiOS G1100 and also name of network connection I still found an unknown phone and a tablet showing under unknown devices connected to my pc.

Found by looking in "my pc", then "network".

 

Computer Doesn't Recognize the DVD Drive Since Upgrading to Windows 10

That is correct. In Device Manager. there is no category "DVD/CD-ROM drives".

There is no "Unknown device" showing in Device Manager.

I clicked on each of the items in Device Manager to see the listing under each item and did not find "DVD/CD ROM drives" or "Unknown device" there either.

 

Well, oddly enough I managed to resolve this. I removed the devices under Unknown, then attempted to install an external USB wireless device (Realtek chipset). I used the installation disk for Windows 7 since there didn't appear to be one for Windows 10. When the OS set up the new device, it also rescanned and installed the other network devices... Properly this time! I uninstalled the new external device and all seems to be well with the world. I have no idea why this worked.
