This afternoon i had a 2.5.1 epmp1000 ap lockup. A remote reboot fixed the problem but now when i log into it and try to change any settings I get this message:
14:21:08 Configuration save failed.
Password can not be set, the Cambium-ID is absent.
Are you using cnMaestro? If not, can you make sure cnMaestro is disabled under Configuration->System and then check to see if you are able to save other settings?
Also you may try to enable Remote Management(if it is disabled) and:
1. Delete Onboarding Key manualy
2. Enter proper Cambium ID and Onboarding Key for it.
Remote management was disabled, I had to do as you said in #1. This unit has never had remote management enabled so I'm not sure what caused the error.
