Hi all

I'm experiencing a strange issue with my point to point setup, based opn 2 WA7210N (used to connect 2 different building, 200mt far from each other)

in the last 4 days the link seems not to work due to some strange behaviour on the client one
this antenna connects to the main hotspot one, (+51 dbm avg,) but after 5 seconds looses the signal, got it again and then looses it again.
at this point only power and LAN (solid) led are on.

i've noticed that once this happens the main antenna, after the survey, shows 0-8dbm, and effectively seems that is not transmitting.
i've tried to use one of the other antennas of the hotspot, but the behaviour is the same and i can confirm that the "sender" antenna seems to have the same 0dbm issue once the clien one connects to it.

already reset
IP is fix, correct and the same one of the last 4 years


scratching my head waiting for an advice
