RFS4000 unadopts AP's when RSSI below - 80 dBm

[Boris1]

Hello guys!
Want to ask you to help me in issue with my network.
Im noticed that my AP's starting to unadopts if RSSI level decreasing below -80 dBm. At this time AP's config mode changes from "configured" to "sheduled" and than it disappears from adopted devices. Mesh links are working, device behind AP can reach network, but AP can't adopt reliably.
Where should I look for a problem?
WiNG 5.9.2.5, AP7562, RFS4000.
Thank you!

Hi Boris,
Adoption status is nothing to do with dBi except mentioned AP is adopted on a mesh link. Can you use "sh mint id on ap7562-XXXX" first to determine AP's MINT ID. Than use "mint traceroute XX.XX.XX" to check communication path between controller and AP.
