anyone else having there epmp SM going to Default on clients ends. until now i had encounter over 10 Client with NAT on the Epmp, having the SM going to Default completely. also the Router Cambium CN Pilot R200/R201 with eh FW 4.2.3-R4 had 4 costumer having their router going to Default.
Just curious - on the ePMPs do you have "Reset Via Power Sequence" disabled? (on Tools->Backup/Restore page)
As a matter of policy we disable that feature on every device. Rarely seen a problem (more frequent with Ubiquiti PtP gear we've resold) but we've definitely had a few instances where blinking power triggered default.
For me too, I disabled this feature and solved the issue.
