Hi,

Can you please share the complete kernel logs from boot up until you encounter the issue.
Also, can you share the exact reproduction steps?

Regards,
Gigi Joseph.

reproduction steps is nothing special, it just happening, no special pattern, timing.

it is irregular.

Hi,

1. Can you please tell me the AP that you use?
2. Can you confirm if you see the issue with another AP?
3. Can you share a WiFi air sniffer log?

Regards,
Gigi Joseph.

> 2. Can you confirm if you see the issue with another AP?

i am afraid not, testing with more recent AP now.

> 3. Can you share a WiFi air sniffer log?

i haven't tested it.

Hi,

should i  have to calibrate wl1801?

EFM iptime N104 (802.11g, 802.11b, 802.11n), 2008.12:

-> wlcore: Beacon loss detected. roles:0x1 frequently

ANYGATE RG5500N(802.11g, 802.11b, 802.11n), 2012.12

-> wlcore: Beacon loss detected. roles:0x1 seldom

i tested following 2 AP, one is works the other is not.

Hi,

What we need to see is if the problematic AP is sending beacons or if the wl18xx is indeed missing them...
Based on the description you have given above, it looks like an AP issue.

Is it possible to get a WiFi sniffer log?

Regards,
Gigi Joseph.

Hi,

is there wifi sniffer tool for am335x or other method?

if yes then how to use it?

Hi,

Monitor mode is not supported on WL8.
I think you need to use some other sniffer tools... Since I don't have the same AP with me, the only way to progress is having a sniffer log.

Regards,
Gigi Joseph.

Hi,

AP? you mean am3352 cpu? or AP

i think my board has problem,  tested it with 4 AP.

i see "beacon lost" messages with ALL AP(iptime 3, anygate 1).

previous test was wrong. my board send error message "beacon lost" with ALL AP.

found that error reason, need RF matching for my board.

in AP MODE(am3352-wl1801), it seems have no problem.

but in STA MODE(am3352-wl1801),

if the board(am3352-wl1801) close to AP(iptime N5-r1) about 5 cm.

it works fine, then

the board(am3352-wl1801) move away from AP(iptime N5-r1) about 1 M.

then beacon lost message pop up.

the distance between AP(iptime N5-r1) and board(am3352-wl1801) does  matter.
