Hi! I have been using for over 8 months now, almost 9 and when I used to use Linux Mint, my network was fine.
On CachyOS, it was slightly slower but changing my DNS kinda resolved it, though I had to do it once a week or so.
Ever since I switched to other distros like Fedora (which I really like, specifically KDE Edition), I have begun seeing weird networking issues such as high latency in Minecraft Java but not browsing and Roblox through Sober.
Something weirder is when I switched back to Windows to test it out with all my manufacturer's updated drivers, Linux kinda seemed to have changed something which made it worse on Windows too.
Now my network seems to randomly disconnect at some times, my downloads are failing and my latency has been at an all time high.
I used to have 19ms ping on any Roblox games, now I get over 200-500ms easily or sometimes spikes to 2000-3000ms.
I have asked my manufacturer on their Reddit for updated packages and I am waiting for a reply.
I hope I'm not alone because I think I saw people complain about it too, but for slightly different cards and on older kernels.
I talked a bit to Gemini, and apparently the driver module in the Linux kernel got worse and worse from 6.1-6.2 to 6.4+ and so on.
I also want to know whether some of this community know whether maintainers are actively trying to mitigate those issues for my specific card and similar cards on the rtw89 driver. I want to know about official fixes, not third party drivers or even workarounds. I know disabling wifi.powersave in Network Manager works, but it is a workaround.
I also heard Linux kernel version 7.3 is performance focused, so I wonder whether later releases could be focusing on networking improvements, especially from those weird Wi-Fi cards.
Anyways, thanks in advance for reading all this and I hope it get fixed soon.
