You need to provide more information than just "wifi not working" - there is more than one wireless network adapter, and we would need to know what chipset you have to better understand the issue.

ok .
My chipset is hp laptop 14sdk0093au with amd ryzen 3500U cpu .
On the latest update the wifi service is not working anymore, lukily I had a system snapshot through timeshift . Now I am using that previous snapshot and i can use the wifi now ...
I humbly request the devs to fix this problem as soon as possible.. Thank you.

Well its ryzen 5 3500U

The CPU type is not a wireless chipset. We have limited time, and you need to provide more information than a laptop model. Feel free to re-open the bug when you have looked into what wireless chipset you have or troubleshooting wireless connections not working, but with the amount of information you have given, there is nothing we can do.
