900Sm losing link with Ap

I am having an issue with one of my 900 ap loseing 4 sm at the same time that are > 2 miles. the jitter is staying in the 2 and 3 range and the path is clear of any trees and obstuctions. i have made sure the software is all update to 8.15 and the frequency is the same color code is the same and mileage is set for 10 miles on the ap. the drops last like a couple of minutes and then the sm’s reregester. has anyone had the same problem or issue?

We are dealing with this problem right now. I am about to climb the tower and replace the AP+Antenna to see if any effect. 'cept we are keeping at firmware 7.3.6, because 8 is said to suck

Are you running prizm?

Well, That did very little. We are ordering a Pac Wireless grid dish. Will post results.

not running prizm

I’m interested to know what does prizm could possibly cause. I think I read something similar in another thread. Are you referring to prizm with auth or without?

Is it the 15dBi grid?
