Wireless Disconnects on Station Mode - No Beacons Received

Hey everyone,

I have a mAP Lite that is configured to connect to another Wifi Network. For some reason, the wlan1 on the mAP Lite disconnects EXACTLY every 20 minutes!
Code: Select all

I've spent the whole day looking at other Forum posts, but nothing seems to help me investigate the issue.

Does anyone have some advice for me?

Switch channel on the AP if you can and ideally avoid 2.4 GHz entirely, way too much interference.

Maybe you can tell us more: the LOG is taken at what point? The AP or the mAP. I assume the mAP.
is this a setup with multiple AP's with different frequencies for the same SSID (such setup=OK!) and the mAP roaming ?
Looks more like it is one AP that has the hablt of changing it's channel every 20 minutes, without telling the clients.
I hate to see the mAP drop/lose it's IP address.This probably also drops all open (TCP) sessions.

Just guessing: CAPsMAN channel reselect interval every 20 minutes ???? Should only be done when nobody needs connection? eg. 3:00AM every day.
