802.11r broken on Snapshot builds with MT76?

Installing and Using OpenWrt Network and Wireless Configuration
1

At home I have a setup with 3 Archer C6 v3.2, one is the main router and the other two are configured as access points (all running snapshot builds since this device is not yet in 21.02 builds).

I'm using two separate SSIDs for 2.4 and 5.0 GHz networks. All devices have the same SSIDs and passwords, and are configured with fixed and non-overlapping channels using WPA2-PSK.

In some situations when roaming from one AP to another the mobile devices take a couple of seconds (~5 seconds) to switch to the closer AP. While this is a minor annoyance for normal Internet browsing, it causes issues in VoIP calls.

I'm trying now to enable 802.11r to see if I can improve the roaming across the different APs. I tried the basic stuff (enabled 802.11r in LuCI and made sure that all devices are configured with the same mobility domain), however when roaming from one device to another the transition is not seamless.

For example, with an iPhone, with ping running to a local IP, when the transition occurs there are about 4 to 5 lost packets (i**.e. 4 to 5 seconds without network connectivity**).

I've also tried to change from "FT over DS" to "FT over the Air" to no effect.

I've increased the hostapd messages and I am checking via logread, see below. I move away from the monitored AP at 20:49:09 and I return at 20:54:53. During this time ping fails for at least 5 seconds.

While I am getting the message "WPA: FT authentication already completed - do not start 4-way handshake" which seems to indicate that 802.11r should be working, I am also getting the message "daemon.err hostapd: nl80211: kernel reports: key addition failed".

I will continue my troubleshooting, but I would really appreciate if anyone has any suggestion or insight to share about this issue.

Thanks!

OK, changing back to "FT over DS" makes the error "daemon.err hostapd: nl80211: kernel reports: key addition failed" go away but then it seems that 802.11r stops working (since I stopped seeing message "WPA: FT authentication already completed - do not start 4-way handshake"):

EDITED: the error "daemon.err hostapd: nl80211: kernel reports: key addition failed" also appeared now with FT over DS, so it seems to be unrelated to this config.

Well, it seems that 802.11r is definitively broken. I am getting many daemon.err hostapd: nl80211: kernel reports: key addition failed errors on the three devices (as seen below in one device this error happes every 10 seconds).

I believe that for now I will have to disable 802.11r and wait for this to be fixed in the future;

Has this been fixed in recent snapshots?

I’m using a snapshot from beginning of October, which still has this issue. There are many changes in the m76 drivers committed in the last two weeks. Perhaps it’s time to test with newer snapshots…

I'm using a Belkin RT3200 with a snapshot from about 13 days ago and enabled 802.11r. Roaming between APs seems to be better now, but I now have one iPhone that causes STA-OPMODE-N_SS-CHANGED and deauthenticated due to inactivity issues:

A ton of STA-OPMODE-N_SS-CHANGED messages along with 3 deauthentications within 10 minutes. These issues did not show up until I enabled 802.11r

Same issue here with the Netgear R6020 using openwrt-21.02.1-ramips-mt76x8

What's the latest on your RT3200?

I haven't tried 802.11r since then
