Opinion's Please-5700SM Signal error

Good day all, I have 6pcs 5700SM’s that in the “AP Eval Data” show RED colored RSSI numbers and power level is NA.
They still work and route.
My 5700AP show’s it’s rssi/jitter/pwr properly.
My audio aiming headset does NOT work on them.
I have blown config’s, factory defaults, newest sft, CNUT, etc
Are they defective? Life expentancy estamate? Any idea’s, comments?

Let Us know what you find

I would do two things:

1 - reflash the firmware
2 - make sure the module is calibrated. see: http://motorola.canopywireless.com/supp … d=187&c=15

Good luck.
