New m9 plus deco unit not accepting connections - older firmware
I added a new m9 plus to my network. It seems like it is happy, it shows up in the app and the light is green, but devices are not connecting to it.
I noticed my existing deco's are all at firmware level 1.4.3 build 20200918 Rel 75286. The new device is at Firmware Version 1.2.12 Build 20191014 Rel. 42025.
When I look at my new device all it will show is "Deco Health Check: Deco is working well"
Seems like maybe I need to force the new deco to update firmware, but as the main deco is already current - the firmware update option doesn't do anything.
Is this likely my problem? how do I update that deco?
