On Gig1, getting 250Mbps downloads

I used to be on M500 and would get 500Mbps or more most of the time, but having upgraded to Gig1 I get between 200Mbps and 600Mbps downloads. Tends to be slower in the evenings and I am measuring a wired connection. I am in modem mode and using a Unifi Dream Machine Pro, which can handle up to 3Gbps, so no bottleneck there.

My Hub 5 has 31 bonded downstream channels with power levels between 0 and 2 dBmV. Tried to restart and the usual other tricks. Any suggestions?

My initial guess is local network congestion. Try setting up a BQM https://www.thinkbroadband.com/broadband/monitoring/quality

Check this site in router mode to ensure you are getting full speed to the HUB over the VM network:

Are you using the Speedtest on the UniFi Network Application? It’s on the bottom left of the first screen. I also have a UDM-Pro and get full speed most of the time. The UniFi Speedtest is very good as it uses about 6 targets to get the speed. If you have a syslog server you can see all the servers, also perhaps it’s also in journalctl if you use ssh to go into the UDM-Pro.

Yep, I am using the Unifi speed test most of the time. I have tried a few others, but they get the same result.

Just checked it uses 10 servers. Journalctl -r shows all the servers.

I think best thing to do is set up a BQM as said before.

By the way you will have 32 downstream streams and 6 upstream, you cannot see the 3.1 streams as there is a bug in the Hub5 firmware and they are not displayed.

Thanks - the lack of 3.1 streams was odd, so that is good to know. Things seem pretty good right now.

The UniFi speed test seems to be, well, broken. I wouldn't be surprised if the UDM-Pro settings have got a bit messed up, but I can't find where! https://www.waveform.com/tools/bufferbloat?test-id=69610868-7488-4d9b-972d-2821cfc769ac is showing 811Mbps down and 103Mbps up, so I am going to use that for now.
