If your WIFI signal is strong but you can not connect to the internet then keep reading in order to find out why this happens and what can you do to fix it.
One very important thing to know and understand is that WIFI and the internet are two different things and that they altho connected and working together are basically 2 things.
WIFI is a name for a group of technologies that are using radio vawes to connect to the router in order to access the internet. The Internet itself is series of computers all connected in LAN. Think of WIFI like some invisible cable that connects your computer to the router. When we put things into perspective this way it becomes clear that we can indeed have a strong WIFI signal and that we are connected to the router but the router itself is not connected to the internet.
So basically troubleshooting an internet connection is troubleshooting the router itself. The most common approach is to reset the router, turn it off, then back on, check cables, etc. But be sure that if your WIFI signal is strong and you can not access the internet it is a router issue.

Error Causes
Microsoft sent an email to users on the Dev build channel saying that the company intends to push some builds that don’t represent what consumers will receive with Windows 11 when it officially releases. In other words, these are going to be some rather buggy builds that won’t be too enjoyable to use.
The company recommends users switch from the Dev to the beta channel if they aren’t prepared to deal with the instability.
We’ll have to wait and see just how buggy these builds are, but if Microsoft is actually sending out a warning about them it is very likely that builds will be plagued with issues and maybe even stability problems.
