Windows 10: 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.

:)

 

"No Internet" on Ethernet but WiFi works.

Hello,

First of all, thank you for your reply. Here's the answer to your questions.

1. I just checked, LAN is enabled in my computer.

2.

• ipconfig /release, ipconfig /renew: the result was posted in the main post. I did this according to another post similar to mine in Microsoft Community.
• Turned my router off and on again.
• Turned off my WiFi and left Ethernet enabled, internet still unusable.
• Updated my driver several times, disabled automatic driver update of Windows.
• Replaced the cable to an entirely different one, still unusable.
• Tried every slots of Ethernet cable at my router.
• Tried to access 192.168.1.1 while plugged in the cable and enabled WiFi, can't access with "too long to response"

Thank you.

Hi,

We would like to know more about your concern.

1. Have you check in your control panel if LAN is also enabled?

2. What have you done so far to resolve the issue?

Thank you.

 

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?
