900 SMs and BER errors.

Good morning WISPers.

I have a few 900SMs that are suddenly getting BER errors. The primary and secondary numbers will change just looking at the page. These are P9 boards with 9.0 software.

These links were installed on the lower end of good, but they always got 90-100% uplink and downlink.

What should I do with this?

Thanks,

Jakkwb

Probably interference.
