Dual Boot Windows10/Ubuntu 22.04 WiFi Constantly turns off/on. Connection is much worse compared to Windows. Ideapad 5 16ACH6. Network Adapter: MT7921

I have been beaten. Went over hundreds of possible solutions and nothing worked as I wanted it too. Including starting completely from the beginning.

As described in the title I have setup a dual boot on an Lenovo Ideapad Creator 5 16ACH6

With a network card output of: sudo lshw -C network

Extra info:

Windows's fast start up is disabled.

BIOS Fast Boot is disabled.

Ubuntu has been ran from a completely powered off state multiple times.

Problem described: WiFi on Ubuntu is noticeably slower and response times are much bigger. In intervals of about 15min the WiFi cuts off for about 30 seconds. To me it seems like the network card stops working. WiFi setup is 2.4GHz and 5GHz two bands set up with different names so I doubt that the system is trying to jump between networks.

I am not that keen on having a 5GHz connection. But I want it to be stable. That is my goal.

I would appreciate your help a lot since I have been battling this monster for about 20 hours now in the span of 2 days.

If you need any other information let me know :)
