Hello!
I tested the Archer MR200 device removing the patch as you suggested:
package/kernel/mac80211/patches/600-23-rt2x00-rt2800mmio-add-a-workaround-for-spurious-TX_F.patch
... the error still appears, but the driver is still working as of now.
Here - reporting my dmesg

To cause it, it seems a good technique to use a device as far as possible from the AP, but not enough to disconnect / stop working.
A reauthentication may be required to use the AP again,

where the xx:xx... mac is an iPhone SE, the x2:x2... is an Android device.
thank you very much for the help and all.
For the moment I am not sure about the situation still, so I think further testing would be needed. Hoping someone experiencing this problem can come up and give some more hints / tests on different hw.
Thank you to all,
Enrico

Hello guys, and sorry for the big CC list.
I would like to point out about a bug who survived for years - at least from 2015 until now, regarding the Ralink driver getting stuck, and in some cases not being able to recover.
The problem manifested with an MT7620A chip, and the wireless card inside the WL-330N3G device.
The error message is in rt2x00/rt2x00queue.c .
This bug was discussed, and a patch proposed, in this thread:
https://lists.openwrt.org/pipermail/openwrt-devel/2015-September/thread.html#35778
I would like to help if possible - I have the have both an Archer MR200, and the WL330n3G hardware.
BTW, the Archer MR200 is a nice MT7610 device, and the problem manifests itself, see:
https://forum.openwrt.org/viewtopic.php?id=64293&p=6
Any help, hint, anything would be apreciated.
thank you to all.
First I would try to remove this patch:
http://git.lede-project.org/?p=source.git;a=blob;f=package/kernel/mac80211/patches/600-23-rt2x00-rt2800mmio-add-a-workaround-for-spurious-TX_F.patch
and see if it makes things better. However I think for the stuck problem
we need tx status timeout mechanism similar like for rt2800usb.
Attached patch can mitigate "Dropping frame due to full tx queue"
errors. I did not test it, so it can be totally broken.
Regards
Stanislaw
