YouFibre / You8000 saga continues – their router works, my previously working UniFi gateway no longer does, and I’m now ready to leave
Following on from my previous You8000 post, I’m now at the point where I’ve told YouFibre that if this isn’t sorted tomorrow, I’ll be leaving.
Quick recap:
I was on You2000, using a UniFi Cloud Gateway Fiber directly connected to an Adtran SDX622v XGS-PON ONT.
It worked perfectly and delivered essentially the full 2Gbps symmetrical service.
I upgraded to You8000.
After the upgrade I was getting roughly 6–7Gbps upload but only 2.5–4.6Gbps download, despite my contract stating a minimum of 7Gbps in both directions.
I reported this to YouFibre.
Support remotely reconfigured my ONT.
That completely killed my fibre connection.
It then happened going into the weekend, when I discovered YouFibre telephone support is only available Monday–Friday, 9am–6pm. Online chat attempts weren’t getting answered either.
My own UniFi U5G/EE failover ended up keeping the entire house, CCTV, etc. online for the weekend.
Eventually YouFibre investigated and found that apparently the ONT serial number was wrong at their end.
They corrected it.
I then connected the supplied YouFibre Hub Pro directly to the ONT and, finally, their router started working.
So you’d think that would be the end of it.
Unfortunately not.
My UCG-Fiber, which worked perfectly on this connection before YouFibre started changing the provisioning, will no longer obtain a working DHCP lease.
The physical side is fine:
Adtran SDX622v XGS-PON ONT
10GE handoff
UCG WAN negotiates at 10GbE
IPv4 DHCP
No PPPoE
No WAN VLAN
Smart Queues off
I’ve now tried:
Power cycling the ONT
Leaving the ONT disconnected to allow the DHCP lease to expire
UCG native WAN MAC
MAC cloning the Hub Pro WAN MAC
Testing the alternative MAC printed on the Hub Pro
Reconnecting YouFibre’s own router to prove the fibre service itself works
At one point, cloning the Hub Pro WAN MAC caused the UCG to receive a 100.106.x.x address, but still no usable internet/static-IP service.
Using the UCG’s native WAN identity, it currently doesn’t obtain a usable IPv4 lease.
I’ve now specifically asked YouFibre to escalate this to their network/provisioning team and:
Clear the DHCP/BNG/Kea lease
Clear any existing CPE/MAC registration
Allow my UCG WAN MAC to obtain a fresh lease
Restore the static IPv4 service
Leave the now-correct ONT serial-number provisioning alone
The UCG WAN MAC has been provided to them.
What is particularly frustrating is that this exact UCG-Fiber worked on YouFibre before their changes. I haven’t suddenly introduced a new router and asked them to support an unknown setup.
I’ve gone from:
Working 2Gbps service → You8000 below contractual minimum → YouFibre remotely changes ONT → total outage → no weekend support → YouFibre discovers incorrect serial number at their end → their router works again → my previously working router no longer gets the correct DHCP service.
I’m now going around in circles with support despite providing them with fairly detailed diagnostics.
I’ve told them today that if they can’t get this resolved by tomorrow, I’m leaving.
I’m not expecting YouFibre to provide technical support for UniFi equipment. I am expecting their network to issue a DHCP lease to the same third-party router that worked perfectly before they changed the provisioning.
Has anyone else had YouFibre support successfully clear the BNG/Kea DHCP/CPE registration after switching between their Hub Pro and a third-party router?
If so, what exactly did you have to ask them to do to get through to someone who understood the problem?
At this point my £79 UniFi 5G Backup has provided a more dependable internet connection than my 8Gbps fibre service, which isn’t quite how I expected this upgrade to go.
