Uncharacteristically slow wifi on Bazzite only

Bazzite

I tried getting some help on the Bazzite Discord but I got no response. I’m trying here.

I am getting very slow download speeds on wifi while using Bazzite specifically. I’m dual booted with Window 11 on its own separate drive and the issue isn’t a problem there, nor am I experiencing generally slow internet on any other device. Here is my wifi speed test on Bazzite when communicating to the most local server to me:

Due to the age of my account here, I can’t post images of my other speed tests. The speed test for wifi on Bazzite is clocking about 23.60 Mbps and Win 11 is clocking 472.65 Mbps which is the expected speed range I should be getting. I’m also getting around 470 Mbps on my other devices (phone, tablet, other computers). Ethernet speed tests are more or less the same between the OSs: 90-95 Mbps.

I looked around to find some troubleshooting steps on reddit, github, discord, and this forum and attempted those steps from people running into similar issues. Here is what I’ve tried:

-Set metered connection to “no”. Issue persists.

-Turned off IPv6. Issue persists

-Turned off power-saver mode. Issue persists.

-Tested with iwd on and off. issue persists regardless.

-Did a system update yesterday. issue persists.

I use the built in wifi card that shipped with my mobo. Mobo is ROG MAXIMUS Z790 HERO BTF and built in card is Intel WiFi AX211. The only primary difference between the Windows 11 and Bazzite installation unique to wifi is that I had to install the asus driver for the wifi card to get it to connect to my network. Bazzite worked OOB. But since I’m getting expected speeds on everything else, it doesn’t seem like the asus driver is doing anything uniquely special.

Does anybody have any ideas on some additional troubleshooting steps I can take to improve the wifi performance short of doing a full reinstall of the distro? I’m not quiet sure where to go from here beyond doing the distro reinstall hail mary. Also if anybody needs anymore info about my system for troubleshooting, let me know.

If you already did sudo nano /etc/NetworkManager/conf.d/wifi-powersave.conf and pasted [connection] wifi.powersave = 2 , then restarted with: sudo systemctl restart NetworkManager and it’s still slow, then you need to have both ip4 and ip6 turned on. No kidding, I don’t know why, but yeah, don’t turn off ip6. I know it looks irrelevant, but I did my testing and you still need it for some sites.

I have just been through this exact issue, is your upload speed the same on both windows and Bazzite, but your download speeds are throttled? That was the case for me, and my fix (if i remember correctly, i tried so many different things) was to force the card to use wifi 5 instead of 6, as it was more stable. I went through a lot of troubleshooting with Gemini and i was able to get it working at full speed after an hour or so of back and fourth lmao. I just went to look for the chat but i deleted it! Hope this gives you something to try.
