Public bug reported: I am facing intermittent connection loss over 5GHZ WIFI on relatively fresh installation of Kubuntu. To clarify during the issue, it appears as I am still connected to my wifi, but the speed plummets to 0, and I can't load basic web pages. This is happening on a desktop with a motherboard with built in wifi. (https://www.asus.com/motherboards-components/motherboards/prime/prime-x870-p-wifi/) This desktop didn't encountered this issue on windows11 (to rule out the possibility of a motherboard hardware failure)
