I8s seem fine.
In normal conditions, small units boot to space clock without incident.
Occasionally cycles to "want to connect to existing internet connection?" Select my home network and click continue. Cannot connect to this network. Go back a couple of times and then forward and sometimes it finally connects. I have these small units at different places around the house, some closer to the router than others. All seem to have problems intermittently. I have rebooted the router and the ooma router. The next thing is to reboot back to the Comcast modem and reconnect in order of connection. It seems like the units forget their connection and have to be reminded. Any ideas what is  happening?
