Access • Re: Configuration settings for Sonic fiber for Ubiquiti Dream Machine?

To be clear, I just followed the "auto" config settings provided by Ubiquiti after plugging it in to the wall outlet and provided Adtran ONT, and it kinda works except for the issues.

When you're experiencing the issue, have you tried to isolate it using ping, mtr and traceroute? Do you have significant errors shown on your internal or wan ports if you look at /network/default/ports/portManagement in the ui

@kgc - the Ubiquiti UI would report disconnections and high packet loss from the Sonic.ISP network.

I actually just got a reply from Ubiquiti an hour ago. Ubiquiti's UniFi Routing & Switching escalation support team said they did their own troubleshooting and can pinpoint the the "Adtran SDX622v XGSPON ONT" model as the root cause for the internet disconnection issues. They acknowedged that there is an apparent known issue with Adtran ONT having interoperability issues with the Dream Machine SE (and similar models). Their recommendation to customers is to get the ONT swapped out to a different model with the ISP's help, while the stopgap solution for end-user is to put another switch/router in between just to offset the issues caused by Adtran ONT.

Definitely very underwhelmed with the transition to Sonic fiber so far given it’s been less than smooth
