I have a couple of these in the shop floor just to test as AP and SM. Been runing for months but currently primarly deploy PMP450 gear. I upgraded them to 3.5.1 with web interface. Now no matter what I do they both think I am logged in as read only even though I am logged in with the administrator credentials. Any idea what would do that?
I’ve never seen this happen, that’s very strange! I’d reset them to factory defaults and see if that corrects the issue!
Taking them down and doing factory defaults resolved it.
