    No internet on ethernet, wifi works


    This happened suddenly this morning. Connections and internet were working fine until it didn't. This may have started shortly after I disconnected from my VPN, but I can't be sure.

    Important: this behavior is happening on 2 ethernet connected PCs.
    WiFi works fine on the laptops.

    In Network Settings > Adapter settings there is a red X over my TAP-Windows Adapter v9 and on my VPN adapter.
    The Local Area Connection adapter has no x.

    Diagnostics say there is a network cable unplugged. Both PCs.
    Network devices are all enabled in Device Manager.

    I can ping all PCs and laptops. So the ethernet cable connection from PC to router is OK.

    The router is a Trendnet TEW-827DRU.
    I have restarted the router and the modem.
    I have disconnected all ethernet cables and tested each PC one at a time.

    I suspect the problem lies in the router. Otherwise why would 2 PCs have the same problem?
    Looking for any help or possible tests or solutions.

    OK, Internet is back.
    I reset the router. Had to reconfigure all the settings. Everything working now. I think the reset did it.

    Those 2 network adapters still have the red X on them. So is this normal? Do the TAP adapters on enable when you run the VPN or whatever Windows component uses the TAP-Windows Adapter v9?
