Based on this thread I bought a IP3M-941B for a baby camera. Meets expectations, with one small issue.
Like many I run dual networks, one for dodgy devices like cameras (no internet access), the other everything else.
The only issue I have is that it won't connect to Wifi if it is on an non-internet+static IP. I could see in Unifi that the WiFi client was connected, but it was never pingable.
Connecting it to the "real device" network (so internet + DHCP), works fine. Not sure if it was static assignment or the no internet, but it does not like to be isolated :/.
Going to play with it some more and see if I can isolate the issue. Anyone else experience this?
