Sorry for the late answer.
We are now on 4.6.2
We no longer upgrade since:
a) with 4.7 it is very difficult to downgrade, the downgrade is someway blocked.
b) CPE suddently disconnects from the AP and stay offline, need an hard power cycle to reconnect to them
c) User experience is terribile, no settings changed, plain vanilla network.
CPE in bridge mode, and some in NAT mode.
We reverted to 4.6.x and everything was now fine.
Try to upgrade a small portion of your network, maybe 1 AP and it’s SM’s to 4.7.1 and start there. Work closely with support if you experience issues.
For some reason my quote reply didn’t populate correctly. I was responding to Fedor (Cambium) earlier in the thread who indicated they were able to duplicate the issue in their lab and I wanted to know what Cambium was able to do to duplicate the issue. I put my ePMP 3000 APs onto the latest but I’m not sure I want to touch my 2000/1000 as that seems to be where most people are having issues.
