I think this may be an issue with the UDM/UDMP and a recent firmware/software upgrade, we have been seeing the same problem on a number of connections.

Hope fully the upcoming v3 of the software will settle it back down

Hi,

Sorry yes all sorted however my router has lately been dropping out. I keep getting this message

Packet loss detected. Please restart your modem. If this issue persists, please contact your ISP.

I called the ISP Hyperoptic who say they have seen no drop outs whatsoever and all tests are fine on their side. So now I am left so confused. I used this cable Cable from the Adva box to the UDM Pro port 10.

Exactly what circuit is this say ou mention Hyperoptic? You shouldn't be replacing the optic supplied by Openreach on the Adva or it may cause you issues if you report problems.

Good old Ubiquiti firmware quality control (or lack thereof) strikes again eh. 🙈

I doubt the DAC will have any ill effect - it's just passive copper - especially as it appears to have been working perfectly for near enough 12 months. Its possible the ports on the gear at either end have gone awry, but my money would be on le dodgy UI firmware as noted.

The DAC is unlikely to have any effect as it would probably either work or not work - however I believe that when Openreach run dianostics on Advas and the optic has been changed, it flags it as an issue. I was flagging it more for that, rather than the packet loss.

I just updated to latest (non-beta) on one device a couple of days ago and BQM is completely clean - appreciate it may not have same parameters though.

I don’t think they concern themselves too much otherwise it would’ve been flagged up to the OP presumably in the last 12 months of usage and certainly (you’d hope) when it was reported to Hyper and they gave it a clean bill of health.

Hi,

So it's been up and running for 6 days now thankfully without any issues apart from a few dropouts
I never get anywhere close to the 1GB speed I am promised. I spoke to Hyperoptic and they said nothing wrong on their side it must be my hardware which they do not support. Am I missing anything? If I use an ethernet cable from the UDM Pro and connect it to my laptop I am still getting similar speeds. As I can't get anything directly out of the adva box I am not sure what else to do here. Ubiquiti have said it's not the hardware.

The upload speed is 924Mbps. Taking into account IP overhead (1Gbps will be the speed of the Ethernet service and maximum the cable can support - beyond that are layers which add information so reduce the speed a bit). Every time you split a packet into two packets it adds headers. I don't recall what the overheads amount to but 924Mbps you're getting upstream seems reasonable.

So your problem is limited to the downstream speed. Have you done this test at different times of the day? If you're seeing very fast speeds at night which slow down during the day then it may be Hyperoptic's network is a bit busy. I don't know how much capacity they have to each building as it's been a couple of years since I used it myself.

I wouldn't personally care too much about 650Mbps download speeds from time to time as it's not a dedicated circuit but a shared service. If you never manage to get more than this, then I think it would be advisable for Hyperoptic to upgrade their network. You could also consider asking to downgrade to the 500Mbps package, although it will affect your upload speed a bit.

FWIW I just ran one on a 1Gbps uncontended link up to our core and got 845Mbps down and 944Mbps; obviously the test runs to another ISP so there are some cross-Internet elements - it's possible Hyperoptic have some issue with capacity to a specific provider (unify will pick one automatically).. second test was 845Mbps and 948Mbps.. There's some other background traffic but it won't explain 850 vs 950Mbps variation.. I can't say if it's unifi but I know the circuit is uncontended (save for some tiny background traffic).. 650Mbps is a bit low though.. as I said I'd test it more before you do anything.

Sorry - I need to check - If you have Hyperoptic why do you have an Openreach circuit - are you not in one of their buildings or is this a business connection?
