This won’t be a particularly useful reports, but here goes.
In one location, we have an ePMP1000 AP, with a Force 300-25 and a Force 300-16… and when we upgraded to 4.5.6, the F300-16 came back like this. I de-registered her, and she re-regged with the same 0.0.0.0 IP, I rebooted the AP, and it came back the same. I still CAN do a throughput test to her, and she get’s her full 60 Mbit plan according to the built-in AP Wireless link test.
Anyway - NO - I don’t have support files to send in anywhere, we of course had to focus on getting the client reconnected. I downgraded the AP back to 4.5.5 and we called her and got her to power cycle, and that worked.
I’ll try to upgrade this again after the long weekend, and I’ll post back here. This may have simply been “one of those things”, and nothing to worry about…
