Windows 11 No internet access but my internet is working fine

I've managed to get to the bottom of the problem on my Dell laptop.

I have tried everything mentioned in this post and nothing worked, but eventually, I plugged USB HUB which allowed me to plug Ethernet cable and connect straight to the router. This enabled internet connection straight away and I was able to INSTALL WINDOWS OPTIONAL UPDATES. One of those updates was my network card driver, which solved the issue.

I hope this will help others

OK, I had posted a few weeks back that I have had this issue... In desperation, I went and downloaded the latest drivers directly from Lenovo (they are dated June 22 of this year and specifically reference Windows 11 21H2 or later). I'd gone down this road early on with a previous version of the drivers to no avail, but - with these latest drivers - everything seems to work as expected. Struggling to understand where the real issue is. For grins and giggles, I installed Windows 11 on "unsupported hardware" using one of the many methods out there (it's an old Lenovo T430). The WiFi on that machine has worked flawlessly since the get-go under Windows 11. Definitely a head-scratcher.

[Moderator note: There is no mystery. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows drivers are rarely enough. Once the manufacturer's drivers are updated this is solved for most people.]
