Laptop not connecting to wifi

My work laptop is connecting to my home WiFi but is showing “No internet” so I am unable to do anything. My home WiFi is working as other devices are connected so it doesn’t seem to be an issue with the router. I have tried disconnecting from the WiFi network and erasing all the other WiFi networks as well as servers attempts at rebooting. I also tried connecting via Ethernet cable but nothing seems to be working. Just to note I have been connected to the home WiFi with no issues since March 2019 so no idea why it’s happened now. Can anyone help??

Solução escolhida

Might be a driver issue. Was there a Windows update before this problem appeared?

Search for ”Device Manager” and open it.

Look down the device list for “Network Adapters”, double click on it and look for any devices that DO NOT begin their name with “WAN Miniport”. The two will be your Ethernet and Wi-Fi adapters.

Do either have an exclaimation mark in a yellow triangle? If yes right click on it and select “Uninstall device”.

If this doesn’t fixit them run Diagnostic for network connection:

Repairing Internet connection using Windows network diagnostics

  1. Right-click on the connectivity. icon on the system tray of your desktop. ...
  2. Press the Windows. ...
  3. Right-click on the connectivity icon on the system tray of your desktop.
  4. Select Troubleshoot problems.
  5. Right-click on the Windows Wireless network icon on your computer's system tray.
  6. Select Repair.

Let us know how it goes.

Thank you!!! Seems to working now

Hi Brogan,

That is great!

Other readers would probably like to know which solution worked - Device Manager or the Diagnostic repair, as you didn't mention.


Holy crap! It worked!

Thank you 🙏🏼


This worked wonders! Device manager and uninstalling the non WAN mini port with a yellow exclamation then restarting worked for me!

I had a similar problem and removing the devices without WAN worked(even though they didn’t have a triangle). After you’ve uninstalled them restart your laptop and connect to your wifi.
