Hi all,
After a long time of testing it seems the problem narrows down to qrb2210 rb1
and qrb4210 rb2 boards.
After booting, the board connects to the wifi network and after around ~5-10
minutes it loses the connection (nothing in dmesg). A simple ping of another
machine on the local network doesn't work. After, I guess, around 5000
seconds the GROUP_KEY_HANDSHAKE_TIMEOUT message is printked:
[ 5064.093748] wlan0: deauthenticated from 8c:58:72:d4:d1:8d (Reason:
16=GROUP_KEY_HANDSHAKE_TIMEOUT)
[ 5067.083790] wlan0: authenticate with 8c:58:72:d4:d1:8d (local
address=82:95:77:b1:05:a5)
[ 5067.091971] wlan0: send auth to 8c:58:72:d4:d1:8d (try 1/3)
[ 5067.100192] wlan0: authenticated
[ 5067.104734] wlan0: associate with 8c:58:72:d4:d1:8d (try 1/3)
[ 5067.113230] wlan0: RX AssocResp from 8c:58:72:d4:d1:8d (capab=0x11 status=0
aid=2)
[ 5067.193624] wlan0: associated
and after that wireless connection works for ~5-10 minutes and then the cycle
repeats. The longer log with more info and some info with firmware versions,
ids, etc is at the end of this email [1]. Simple wlan0 down and wlan0 up fixes
things for a few minutes.
iw wlan0 link reports the following when wireless network is working:
root@rb1:~# iw wlan0 link
Connected to 8c:58:72:d4:d1:8d (on wlan0)
SSID: void

rx bitrate: 433.3 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 1
bss flags: short-slot-time
dtim period: 1

and this when wireless connection doesn't work:
Connected to 8c:58:72:d4:d1:8d (on wlan0)
SSID: void
freq: 5300
RX: 850615 bytes (9623 packets)

signal: -61 dBm
rx bitrate: 6.0 MBit/s

dtim period: 1

This was tested with three different routers and different wifi networks.
Other devices here do not exhibit this behaviour.
Any hints on how to debug this? Any debug switches I can toggle to debug this?
I am happy to provide more info or test changes/patches if any.
Thanks in advance.
Best regards,
Alexey
