IAP 1101 Red blinkin

[yam]

Hello,

I have a issue with the iap1101
It has the firmware: 2.1.0.100 poe distance is 10 meter.
But the follow problem is: When connectin apple devices and run a speedtest, the AP disconnect and goes red blinkin. It doesnt have internet connection anymore. 30 seconds later it goes flashing green again and everything works fine again. the other 4 ap's doesnt have these issue. (they all connected to cisco swtich)

What can be the problem?

Thank you a lot.
