We were seeing lots of issues, session drops, on our 900 APs in high noise. Rolled back too 16.2.3 now.

Yeah, we experienced that too with 900 and also some 2.4GHz⌠seems to have something to do with noise and/or multipathing issues. Rolling back to 16.2.3 cleaned up everything.

We havenât run into much issues with the 20 release except with one instance of âPLL lock lostâ once this morning with a 450b to a 450m. In the scenario we ran into that was with 20 firmware was trying to connect to a 16.1 release. The installer swapped it out with a different firmware horn before I could get any information.
So far all of the 4 AP/CPEâs that were fully upgraded seem to be working normally, but we have stopped rolling it further.
We have resolved the âBandwidth PLL Lock Lostâ problem on 450b and also a 20.0 session drop issue.
Much thanks to @Eric_Ozrelic for help in debugging the issue. 20.0.1 is now running very well on Ericâs troubled setups.
If anyone else would try 20.0.1 beta it is available now:

If you find any issues, please let us know ASAP as we are aiming to release it soon.
I highly recommend anyone running 20.0 upgrade to 20.0.1.
