RB711 and RBSXT radio module fail

Hello! We have few RB711 and RBSXT and we have problem. Radio module this devices work only one direction. RB711 and RBSXT can scan airwaves and cant transmit, as a result of this, station (radio mode: station)(RB711 and RBSXT) cant connect to base station (radio mode: ap bridge). What we can do, to fix it?
Router OS version 4.17-5.12.
Sorry for my english.

for station mode you must set NAT. Are you sure are configured as it must?

Thank you!
With it here NAT (Network Address Translation)? It is a question of signal transmission by radio. Yes I sure about correct cofiguartion radio module.

it it does not transmit (cannot transmit) AP beacons when set in bridge mode, means TX part of the wifi module has been damaged.

i have the same issue with rb711 too; rx ok (ap listed in ‘scan’) but there is no association (‘authentication timeout’) and there is no ‘trying’ in log on ap side; radio tx failure!? rb worked ok only one month, it’s practically brand new… any solution!?
