WiFi RT2x00 issues Archer C50

Hey there.

I recently acquired some TP-Link Archer C50 for the sake of wifi coverage.

Just a day after I flashed LEDE I had one of them randomly reboot, so I checked the system log in LuCi

The system log was filled with: "kern.err kernel: [104103.690764] ieee80211 phy1: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2"

After checking the other devices, their system log was also filled with that error as well.

I found this string "rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2" referenced quite a few times over the years, but I have yet to find a fix.

Is there a fix out there? Anyone has any insight on that?

Info / build overview:

LEDE Reboot 17.01.4 r3560-79f57e422d / LuCI lede-17.01 branch (git-17.290.79498-d3f0685)

I just flashed one of the access points with the snapshot build. Disabled WiFi everywhere else for testing purposes.

The snapshot doesn't fix it currently.
