Windows 7 and 8.0 bug: Network icon is marked as "no internet access"

Solution 1:

Try the following : Go to Computer -> System properties -> Device Manager --> Network adapters: double-click this entry in the list

  • Now Right-click your network adapter (or wireless adapter) --> Uninstall … BUT LEAVE "UNCHECKED" the box marked “Delete the driver software for this device”
  • After uninstalling, the Device Manager list refreshes. In the blue area near the top of the screen, click Actions, then Scan for hardware changes.This should reinstall the network adapter, and the device driver software for it.
  • Restart your PC.

Solution 2:

In my case (Windows 10), it seemed to be an invalid local certificate created by an old installment (maybe created by Fiddler?) which I had on Windows 8 before I upgraded to Windows 10.

Go to:

  1. Control Panel -> Internet Options -> Content -> Certificates -> Personal
  2. Check if you have a certificate with status invalid
  3. Remove it.
  4. Reboot.
