New to the forum i recently installed Ubuntu 22.04 upgrading via terminal from 20.04. Everything went well as expected but my wifi (only option for connecting to 2.4 GHz) started showing the issue. The downloads start with good speed and then speed drops to 0 every time. I have tried most of the solutions(22.04, wifi keeps disconnecting for a few seconds frequently started with).
Also refered the solution by @chill555 Ubuntu 20.04 Wifi Keeps Dropping still no success. Trying to install Vs-code and other stuff which keep on dropping. Status of lspci -knn | grep Net -A2
