I have 2 devices, both obi 100. One just started this also. Can't be sure when it started because I'm away from the house but it was in the last few days. Later today I plan on remoting into my home network to troubleshoot. Last time this happened it was the software upgrade issue and no longer under a maintenance plan. Maybe I'll have to do another manual software upgrade? But the other obi100 I have which is about the same age is still working.
