Hi @Brian_Helgoe,
I appreciate the level of detail provided. Thank you!
Do you know the model number of the Frontier-supplied router you’re using? The more details you can provide us with about your network hardware, the more light it will shed on the issue.
Your previous post suggests that there may have been an IP address assignment issue to blame the last time this problem appeared.
Do you know if you had assigned the Nucleus+ a fixed IP address the last time it was connected? You could try re-booting your router and any network hardware in the meantime.
