Comment (by ericwong):
I have recently build AA, r41581 for rt3052 based router.
WIFI radio "works" but after I used it for a few hours to about a day,
WIFI radio will "die". What I mean is WIFI radio is still on and can be
discovered in WIFI scan. However, any devices trying to connect to it will
not be able to get IP address or WIFI connection. If I restart the router,
this problem will be gone temporarily but will reappear after sometime.
dmesg shows the same error as the post above.
Since AA currently uses the same BB backport WIFI driver, I think the
source of the problem is probably the same.
I am not sure if this matters but in my wireless configuration, I am also
using 40mhz channel width like this.
option channel '1'
option htmode 'HT40+'
Using this configuration, restarting WIFI will result in this message.
root@Gargoyle:~# wifi
Configuration file: /var/run/hostapd-phy0.conf
wlan0: interface state UNINITIALIZED->HT_SCAN
handle_probe_req: send failed
handle_probe_req: send failed
20/40 MHz operation not permitted on channel pri=1 sec=5 based on
overlapping BSSes
Using interface wlan0 with hwaddr 00:0c:43:30:xx:xx and ssid "Gargoyle"
wlan0: interface state HT_SCAN->ENABLED
wlan0: AP-ENABLED
root@Gargoyle:~#
If I enable noscan, like this
option channel '1'
option htmode 'HT40+'
option noscan '1'
The output will be changed to
root@Gargoyle:~# wifi
Configuration file: /var/run/hostapd-phy0.conf
Using interface wlan0 with hwaddr 00:0c:43:30:xx:xx and ssid "Gargoyle"
wlan0: interface state UNINITIALIZED->ENABLED
wlan0: AP-ENABLED
root@Gargoyle:~#
This means that the handle_probe_req error is related to the noscan option
not enabled. I am not sure if this error is related to the
rt2x00queue_write_tx_frame error.
I am now testing/using my rt305x router with noscan enabled to see if it
will solve this WIFI problem. Will report back if my WIFI radio continue
to die....
I would be happy to test any code changes that may fix this problem.
Please reply here, so I will get a notification.
