AP7522 no wifi on ch 8 or higher

[willemhs]

Hello,

I'm having trouble with my AP-7522 EU-version. When setting the channel of radio 1 (2.4GHz) fixed to ch 8 or higher, my clients doesn't see any ess-id's.
When setting the radio on fixed channel 1 to 7, it's working fine.

I'm using Wing 5.9.4.0 and i tried anything. Factory Defaults, basic setup, diffrent firmware versions.

Can anyone help me out? Perhaps with a working configuration file for AP-7522 so i can test this out?

Even after a factory reset i've got the same issue. Created a GTAC case.

After some troubleshooting they concluded the issue is environmental. I've tested the AP on a diffrent site, where de ESS-id is being broadcasted on higher channel. So indead, the issue in environmental.

They advised me to disable transmit beam forming on AP profile radio (no transmit-beamforming).
Unfortunately this doesn't solve the issue. They adviced a site survey to determine sources of interference and to determine clear channels.
Strange thing is that other brands of accesspoints do work fine at higher channels.

At this point i would try factory default the AP & if issue persists call GTAC for further investigation.

I can't get the AP7522 working on 2.4GHz chanel 8 or higher. Should be so simple, but is just won't work.

Could somebody please post the startup config of a stand-alone AP7522?
Doesn't mather wich firmware (i will upgrade/downgrade to that version). You can zerro wifi the encryption key.

Would be great to test this on my AP7522.

I tried multiple firmware's. Because we used these ap's for years with a RFS6000 controller on v5.7.1.0, i tried to get a stable base on this firmware.

I've just updatet to 5.9.4.1. With channel 7 i can associate, with channel 8 the clients don't see the ESS-id.
Here's the startup-config:
