Interference on all channels over 5GHz band

Hi,

We have 2 sites (total 5 APs) that have problem with high interference on 5GHz band. All clients loose connection for about 2-5 mins. When I check the spectrum analyser I can see very high interference over all channels. I can't find any neighbor that talks loud. sometimes the AP is the only one in that channel. I see high CRC error on all access points in 5GHz. Radioprofile & config is same for 19 sites but just these two sites has problem. All APs are model 130 with 8.4r11 firmware, I updated to 10.0r5 too but still have the same problem.

In the first picture you see the interference and the second pic is after 10 min and it's clear blue without interference.

Any idea?

Thank you in advance.

In cases where I've had similar issues I've used 8.2r6.

You lose some of the dashboard reporting data but it is solid to test with.
