I did a fresh clean install of Ubuntu 22.04 and I am very new to Ubuntu/Linux Kernel. As a result the wifi on my system connects but keeps dropping even though I am sitting 6 feet across from the router. I have it installed on on my HP 15-db1xxx, when I boot up my system. Wifi on startup , the wifi signals initially are healthy but after 4-5 minutes Wifi signals after usage . The signal fluctuation happens when I am using the internet and I loose the connection, for instance, the pages will stop loading and I have keep hitting the refresh button until it starts working. This has become really annoying and has been blocking me at work. I have not encountered this problem with Windows 10 which is dual-booted alongside Ubuntu 22.04.

This problem is driving me insane and disturbing the workflow. This problem never occurs on Windows 10. I have tried cloning https://github.com/tomaspinho/rtl8821ce for the Wifi driver and installed it, but this did not work either.
I have also tried these solutions Ubuntu 22.04 LTS Wi-Fi Frequent Disconnection WiFi randomly disconnected on Ubuntu 18.04 LTS
And they have not worked for me. Please help!
EDIT: So I uninstalled Ubuntu 22.04 and did a clean install of MX-Linux 21 with Kernel 5.10-14, and the wifi is working flawlessly. That problem has long gone but I think we will have to report this bug on the newer kernels. I tried updating kernels on Ubuntu form 5.15 to 5.17, but no luck! Anyways, I think Ubuntu 22.04 is still fairly new and Canonical is working on fixing the bugs. Thanks for the help guys, really appreciate it.
