Sorry for the issues with your mesh system failing to reconnect after an outage. Were you able to get this resolved, or did you still need help on this? Usually after an outage, the issue is generally going to be with the modem needing to fully reconnect with your incoming connection from your ISP. I have a few questions that might help us out here.
If you can give me a few more details, I'm sure we can get things working properly. I look forward to hearing back from you.
