(Desktop)Wifi slow on 2.4GHz and disconnects on 5GHz

Bazzite
1

Hey guys, I’ve been having this problem since I first started using Bazzite, but I’ve just been sucking it up and dealing with it but it’s really starting to annoy me. I’m running the desktop version of Bazzite (KDE) on a 7600x CPU with a Gigabyte x670 Aorus Elite AX mobo. Originally I thought it was just a bug in KDE but I recently installed CachyOS on a seperate SSD with KDE and I can get max speeds on both 2.4 and 5GHz wifi as well as no random disconnects on 5 GHz when I boot into that.

When booted into Bazzite, I can only get 10Mbps download speeds on 2.4 GHz but my upload is fine. I can switch to 5GHz wifi to get max throughput (100 Mbps) just fine but it randomly disconnects after 15-30 minutes and the only to fix it is to disconnect and reconnect. This has been happening for the 8ish months I’ve had Bazzite, but it doesn’t happen at all on CachyOS with KDE.

I’m sure I’m probably not giving enough information, I’m still relatively new to troubleshooting Linux. Please inform me on further information needed! I’ve already tried searching and everything I’ve come across has been for the Steam deck or other handhelds. Does anyone have any idea why my wifi is acting the way it is?

Apologies for bumping my own thread, I have more information that I’ve found. I should’ve used the lspci command in the terminal to get the proper information needed for troubleshooting. I clearly didn’t do enough research before asking for help, and I apologize for that. I know it’s annoying when people don’t put in enough effort before asking for help.

Using lspci reveals that my motherboard is using a Mediatek MT7922 wireless chip. I found this thread on reddit that supposedly contains a fix for the issue. I’ve tried following the instructions (to clarify, I followed the linked github instructions in the reddit post) and I can’t extract or copy files into the directory /lib/firmware/mediatek/ even if I do it through a sudo command in the terminal or if I right click the folder and select open as administrator in the proper directory. It always errors out and says the file system is read only despite using sudo.

I’m sure this is probably just more noob idiocy, but if anyone could help me out, that would be greatly appreciated. I would’ve thought using sudo would be enough to get past that. Do I need to use some form of rpm-ostree to get it to work? Am I even going down the right path, or am I about to mess something up with my system?

Again, apologies for not doing enough research before asking for help. I also apologize for bumping my own thread, I’ve been around forums long enough to know that that’s generally frowned upon. I just really want to use full wifi speeds (100 Mbps while I can only get 15-20ish Mbps on 2.4GHz).

I would use an ethernet cable if I could, but I’m upstairs and the router is downstairs, I would need a very long cable to make that possible.

Yeah those won’t work as /usr is read-only on these Atomic systems.

have you tried “sudo rpm-ostree install mt7xxx-firmware” from this fedora thread?

To be honest, if the above doesn’t work I would create an issue on the github as it would feel more like a bug at that point.

if you’re feeling extremely adventurous you can try packaging those files as an rpm yourself and then installing the resulting rpm. Note that I have never tried this myself, I just know its theoretically possible.

When I do that, I get the following output from the terminal -

“mt7xxx-firmware” is already provided by: mt7xxx-firmware-20241210-1.fc41.noarch. Use --allow-inactive to explicitly require it.

So I would guess it’s already installed and I need to either get a different wifi adapter that has better support on Linux or run a long ethernet cable if I want high/stable speeds sadly.

Thank you for the help, it’s much appreciated!
