WLAN stuck, no more wifi in ap mode

To reproduce Just let the rpi running in ap mode with traffic

Expected behaviour AP MODE in good health

Hostapd conf :

interface=wlan0 bridge=br0 ssid=XXXXX hw_mode=g ieee80211n=1 channel=6 wmm_enabled=1 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 wpa=2 wpa_passphrase=YYYYY wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP country_code=FR ieee80211d=1

Hmm, that is a wireless firmware crash issue. So this just happens whilst running as an AP, nothing special going on? How long does it take before it fails?

[figeac888]

Yes just run as an AP with 1 or more client connected. Failure is quite random, here are the history of fails detected by my watchdog:

01/19/20--02:35:01 : rpi rebooted by cron 01/19/20--02:36:44 : rpi rebooted by cron 01/20/20--10:35:01 : rpi rebooted by cron 01/20/20--10:40:01 : rpi rebooted by cron 01/20/20--10:44:01 : rpi rebooted by cron 01/20/20--10:45:01 : rpi rebooted by cron 01/20/20--10:46:02 : rpi rebooted by cron 01/20/20--10:47:01 : rpi rebooted by cron 01/20/20--10:48:01 : rpi rebooted by cron 01/20/20--10:49:01 : rpi rebooted by cron 01/20/20--13:42:01 : rpi rebooted by cron 01/25/20--19:48:02 : rpi rebooted by cron 01/27/20--16:52:01 : rpi rebooted by cron 01/28/20--17:06:01 : rpi rebooted by cron 01/31/20--08:29:01 : rpi rebooted by cron 02/01/20--14:16:01 : rpi rebooted by cron 02/02/20--15:04:01 : rpi rebooted by cron 02/02/20--15:55:01 : rpi rebooted by cron 02/02/20--18:55:01 : rpi rebooted by cron 02/03/20--08:38:01 : rpi rebooted by cron

Have similar issues when running airodump-ng. Kali Linux fresh installed, after few minutes got this message: brcmfmac: brcmf_sdio_hostmail: mailbox indicates firmware halted

After rebooting started to work, for few minutes and again the same error message.

Also encountering this issue on a Pi 4 setup as an AP with hostapd @JamesH65—brcmfmac seems to crash/halt. Any details I can provide to help track this down?

[JamesH65]

@pelwell Is this something else to send off to Cypress?

Clear step-by-step instructions starting from a stock Raspbian always help, as does anything that increases the chance of failure.
