I have this problem for the last 2/3 weeks. I intalled openSUSE Tumbleweed back in september, and all ran fine, I could play everything that could be played for Linux in Steam.
Three weeks ago, everytime I booted on my Linux SSD, I had internet connection for maybe 10 to 15 minutes, after that, the connection icon appeared with zero white bars and a “!” sign, and when I wrote “dmesg | grep 8852be”, it printed out that the WiFi adapter went to a low power state and could not come back from that low power state.
I reinstalled Tumbleweed at least 5 times in a row to understand what could be the origin of the problem. I tried the “generic” drivers for instead the dedicated drivers, and nothing helped. The only thing that helped to maintain the WiFi connection is not installing any games, neither install Steam on the desktop.
Boot from an older snapshot from before this issue started. If your session works fine then I would think it is a bug with a semi-recent update, so you may just have to wait for the next relevant update or figure out if any system settings changed. If the issue occurs on the older, trusted snapshot then I would start considering a potential hardware failure. Good luck.
Hey Capistro, thank you for your input. Yes, When I first installed openSUSE and had this problems, I tried to boot from an older snapshot. It worked for a couple of hours, and than lost connection again. The hardware is pretty recent: Asus TUF Gaming B550 WiFi II manufactured in december of 2023. There is a GitHub repo with Realtek drivers for Linux for many WiFi adpater, but it didn’t fix the issue
