Hi

Need some assistance. Had an LFC Incident (ONT Software Upgrade) this morning at 1am. Since then my connection has been down. Have recycled my router (DreamMachine SE) and the ONT. Optical connection on ONT is flashing green so seems okay. Am using DHCP. Everything in my Quic Dashboard seems fine. Any thoughts on next troubleshooting step?

Thanks

If you plug a computer directly into the ONT temporarily will it get a DHCP lease?

Found an old laptop with a lan connection. Tried that. Would you expect it to allocate an ip4 address? Didn’t seem to.

Have just disabled dhcp on my Quic dashboard and will try using pppoe once it has timed out.

Are you pushing a vlan over the wan interface at all?

So switched to pppoe and everything is fine. Will try flipping back to DHCP (as per original config)and see if it connects

If PPPoE works I don't think it's an ONT issue.

Are you using early access Unifi-OS on your UDM-SE (specifically the latest release from 2 days ago v4.0.3)? If so, this issue may be relevant to you as it happened to me on DHCP as well.

Just tried DHCP again and it failed so went back to pppoe.

Yep that could be it. I'm using that OS. Interesting how it worked fine until the ONT update cut off my service. Thanks for the info!

I love issues that become ‘not by my issue’ by the time I get to it 😂

Yep, poor timing. OS for UDM Pro SE happened at 1:22am this morning and the ONT Update 1am.

If you still want to use DHCP, you can SSH into the UDM-SE and use these commands but replace xxx.xxx.xxx.xxx with the IP of the BNG you're connected to, and the interface name if you're not using the standard 2.5Gbit port.

ip route add xxx.xxx.xxx.xxx dev eth8

ip route add 0.0.0.0/0 via xxx.xxx.xxx.xxx dev eth8

But note that you'll need to run these every time your DHCP session renews / router reboots.
