After 2 months of testing, antenna changes, more than 100 tests with different CPE, the INTEROP MODE, does not work as it should or at least as they say, you can not go from 40 CPE to begin the problems.
After reading all the recommendations, and do everything recommended follow without functioning.
Validation by MAC Radios, does not work, and every 30 or 40 minutes there is a reboot.
With 45 CPE it does not reach more than 30Mbps.-
I hope in the new firmware help us to use Interop freely to be able to carry a migration more stable and without so many problems.
We have more than 4 AP A5c, of which we are already to lower them of our towers.
