Hello! Ive been trying to setup a new fibre connection for my mum. Currently I have a Unifi router (UCG-Max) and have it configured as to what is required on the 2degrees site. However I cannot get a connection at all. Connection from Spark was cut at 6AM today.

This router was setup at my old flat under a 2degrees fibre connection previously. Differences at the old flat was faster speed (900 vs 500mbps), Static IP and a newer ONT.
When I plugged this in at mums under the Spark connection I didn't need to change anything and it worked fine. Since the switch this morning I haven't been able to get it running through 2Degrees

Steps tried to resolve the new 2Degrees connection:

Restarting UCG and ONT
Double checking all settings compared to 2degrees site
Factory Resetting UCG
Calling 2Degrees twice, they said that they can see the ONT and the modem
Tried enabling the DHCP over ipv6 aswell set to 56 as per another article I found on geekzone

I'm hoping i've missed something obvious :(

WAN settings:

Really appreciate any assistance.

Thanks

Is the new connection on the same ONT port?

Try the other ONT LAN ports. It was likely provisioned on port 2 as the spark connection was still live on port 1

Thanks, tested LAN2-4 on the ONT. Only LAN1 would light up orange, LAN2-4 wouldn't show any lights and the router would see the WAN port as down. I power cycled the ONT while it was plugged into LAN2 and found that it lit up green for a bit before turning off.

From what 2Degrees were saying on the phone, they were suggesting it was supposed to be in port 1

Orange... hmm. What type of ONT do you have?

Other thing I noticed was you selected port 5 on your router for the WAN. By convention its usually port 1 but I don't know that gear so this could be right...

That is correct behaviour. It means only port 1 has a service attached. It may briefly light up on the other ports after a restart while the ONT is waiting for a config.

Port 5 is the default WAN port on these devices

Port 5 is correct for Unifi Cloud Gateways unless changed in the UI.

https://www.chorus.co.nz/help/ont/type-200 it is a type 200 ONT

Can confirm port 5 on the router is the default WAN port

OK. I can't see anything wrong with your config. Does it have a status page? Are you getting an IP?

It's not really giving me much information about the WAN IP, I believe the one in the screenshot is the router itself.

That GW IP of 192.168.1.1 is a bit funky. Even with CGNAT they would not hand out a 192.168.x RFC1918 range. I think you have that plugged into somewhere else?

Try reassign WAN1 on the UniFi to Port 4, then physically connect from whichever port on the ONT to Port 4 on the UniFi. This will tell us if this is an SFP issue or something else.

If this doesn't work, just keep trying different ports on the ONT until you find the right one. If after trying that it still is not working, try disabling the VLAN 10 then trying each ONT port again. Give it a minute or two between port changes.

Unrelated but you probably also want to enable Flow Control and Smart Queues.

Ive unplugged all Ethernet devices from it, except for the AP. Switched out the cable going from the wan port to the ONT and seems to be no change.

Can confirm that 192.168.X address is the router itself.

I might just need to get another router to test.

Then should be on LAN side, Not "Wan 1". It looks like a config issue.

Bit of a left field suggestion follows:

I have a UDM Pro and are with 2Degrees. We recently moved house and when the fibre connection was installed at the new place, I got some curious internet behaviour. There was a physical connection, I could log into the router remotely (I was out of town at the time), speed tests were good, but the router reported the internet as being offline, WAN was shown as disconnected and those at home certainly couldn't access any internet.

After three days of trouble shooting with 2Degrees tech support, it turned out that for some unknown reason the disconnect of the old address had been cancelled, so there were two addresses trying to access the account and, I guess, the same static IP. Once this was rectified, everything just worked.

Any chance that your old 2degrees connection could still be active?
