AX200 Linux very low speeds


I've tried quite a few distros (Manjaro, Ubuntu 22.04 and Suse both Leap and Tmbl) and on all my AX200 has very slow speed compared to Windows (i would say less than a quarter). I've installed different kernels, disabled power save, nothing seems to make any difference. Currently this is what i have :


lo        no wireless extensions.

Link will vary and occasional it can go up to 432 Mbit, far from the 1000 i get on W10. More info :

If anyone has any other ideas, I'm willing to try.  I don't think it's the router, it's a Asus Zen Wi-Fi AX and during my short test it worked perfectly under windows 10.

I've read that it could also be related to encryption and security, currently the network is WPA2-AES. So I just created a guest network with no security, there was no improvement. Link stays at 21 Mbit for 90% of the time, even if the signal strength is quite good.

I tried swapping to IWD and there seems to be an improvement, although it's early to be sure. Now the link varies from 29.2 to 576.4. Still not close to W10

This is what i get under W10. Tried on Manjaro with all kernels from 5.4 to 5.19. Tried ubuntu and variants as well, tinkered with all settings i could think of but no improvement. So i finally gave up, I do expect a performance drop on certain HW (such as wireless ax or gaming perf) while on Linux, but that's usually marginal within the 5%, here we are talking about a 80%-50% drop. If it's not the distro nor the kernel nor the network manager, i suspect it might be the driver that's why i came here for support. Anyway, using this little bloatware for now waiting for a driver update in the kernel.

300+ views, almost two months later and zero replies from any Intel moderators ? No advice no nothing ? This is ..disappointing and something to keep in mind when purchasing my next wireless card, or any other Intel hardware for that matter.

I second this problem.

Researched this problem for days and hours on end. Reinstalling different linux flavours give same result.

Linux mint 20, 21, Ubuntu 22.04, 22.10. All the same.

I played with several iwlwifi options but no solution for slow download, power=off gave me a slight improvement.

Strange thing is that upload is acceptable with 3 times higher rate than download.

I test this with local network to and from a local server.

Wired speeds are maxed out at 1000mbit

I get consistent 400mbit upload and around 130mbit download.

I even opened up my laptop to change the antenna and change the mini pci-e card from another laptop.

Now I'm going to try linux kernel 6 to see if there's improvement.

Maybe this thread is related.

Think there is a slight improvement in 6. Now the link varies between 576 and 648

After days of tweaking and digging I managed to improve my bandwidth greatly with another antenna just hanging outside my laptop for testing purpose.

My conclusion is that my metal laptop enclosure is the culprit of bad wifi reception.

I switched back to stock kernel and only use wifi power management off which still produce slight improvement.
