[TRACKING] Unstable and unreliable WLAN RZ616/MT7922 [FW13 AMD DIY]

This thread has some things that you might try to alleviate this: Poor Wi-Fi performance with AMD RZ616 - #4 by Mario_Limonciello

Hi @Ceremony,

As @lbkNhubert indicated via Mario:

I did locate what I believe was the patch in question.


Now, here is what I would suggest trying to see if it provides any relief.

Grab your device name (on Ubuntu, you will need to apt install iw):

iw dev | grep Interface | awk '{print $2}'

With that interface name, use nano/gedit or whichever editor you feel comfortable with:

sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

edit 3 into 2, save the file.


Open the terminal back up again, check your power save status:

iw dev <interface-name> get power_save

You should see Power save: off

Now, this may not necessarily help. On my own WAP, I am not seeing this issue and I have kept power save on.

Internally, our engineers have had success disabling power saving on their 6E networks.


Same situation and configuration here. So far I haven’t found a solution, and unfortunately the tip with the adjusted configuration doesn’t work either. The WLAN card is not recognized for approx 20 to 30 seconds after login.

$ iw dev <interface-name> get power_save
command failed: No such device (-19)

And the dmesg output looks like this:

[   76.490501] mt7921e 0000:01:00.0: not ready 65535ms after FLR; giving up
[   76.644294] mt7921e 0000:01:00.0: enabling device (0000 -> 0002)
[   76.660565] mt7921e 0000:01:00.0: ASIC revision: 79220010
[   76.745805] mt7921e 0000:01:00.0: HW/SW Version: 0x8a108a10, Build Time: 20231120183400a
[   77.118386] mt7921e 0000:01:00.0: WM Firmware Version: ____000000, Build Time: 20231120183441
[   78.253446] mt7921e 0000:01:00.0 wlp1s0: renamed from wlan0

After a while, the WiFi card appears in the system, connects to the network and the output looks like this:

$ iw dev <interface-name> get power_save
Power save: off

So I guess it doesn’t necessarily have to do with the power settings of the WLAN card.

Is this Ubuntu by chance? If so, I will be filing this bug Tues.

It’s Manjaro, not Ubuntu.

Hi! I have the same issue on Manjaro. My dmseg shows the same errors. Just wanted to add that this problem doesn’t happen when I reboot; only on a cold start.

Manjaro users, if this is the same issue, this will come from this here if it’s the same issue.

for interface in $(iw dev | awk '/Interface/ {print $2}'); do iw dev "$interface" get power_save; done

Sorry, do you mean that the updated firmware introduced the bug?

Sorry, let me clarify a bit.

  • We have done zero testing on Manjaro for Mediatek, so this is speculative.

  • On tested distros Ubuntu 22.04.3 and Fedora 39, we are dealing with a Mediatek firmware bug that created slow down experienced by some users. Ubuntu is updating this, Fedora already has (when you’re updated with dnf). For other distros, this will depend on each distro maintainer to introduce this.

  • I suspect that the issue described here, it likely related and potentially addressed by this update. Since we do not test outside of officially tested distros due to available cycles, fastest way to a great experience is to either keep updating your distro of choice.


Got it, thanks!

I’m currently using KDE Neon on a Lenovo Ideapad 5 14APH8 (6.5.0-15-generic kernel) which uses the same SOC and wifi module. Have similarly unstable WIFI.

Swapping the firmware following this post ([RESPONDED] Slow Wi-Fi on AMD 7040 with Ubuntu 22.04) seems to have improved the dropped connections BUT I’m still getting the odd dropped packet (running $ping -q -O) but nothing like minutes of consequtive dropped packets.
