Gig1 speeds

[RLipscomb]

Hi, I bit the bullet and upgraded my fibre .. I received upgrade pack when going from m500 to gig1 and new hub5.

so far, I am only hitting around 800mbps DL and 45/50mbps UL .. and would be expecting more.

I am using hub in modem mode which connects to my unifi udm and associated AP’s around house.

Network logs are showing lots of warnings and the max traffic rate as 1200000450 bps

Could an insightful person take a look please as not the speeds I was expecting having come from a very good m500 service.

Did you run the Speedtest from the UDM or from a device?

[RLipscomb]

Hello and thank you for responding.

I've run both speed tests over Wi-Fi and over eth and from UDM and device. Same issue.

does it take time to train up as only installed it yesterday afternoon but would have though it would be synched by now.

I've also reset the pin hole in hub, turned my router off and then brought back on line hub first (as modem) and then my UDM.

Thanks again!

Anyone from virgin able to offer any advice etc? The ms all!

There is no "train up" period with VM, it works straight away. Have you got a UDM or a UDM-Pro? What is the firmware level of the UDM and also the level of the Network Application? I have a lot of experience with the UDM-Pro, currently on 3.0.20 and 7.4.156. Could you please supply some stats so we can check out your circuit. 

How to get stats from a VM hub (no need to logon to the hub)

Open a web browser and go to 192.168.0.1 router mode or 192.168.100.1 modem mode

• Click on the “> Check router status” button
• Click on the “Downstream” tab, copy the text and paste into your reply, do not take a screen shot
• Click on the “Upstream” tab, copy the text and paste into your reply
• Click on the “Networking” tab, copy the text and paste into your reply.
• Do NOT post photos or screen shots they will be rejected as they contain MAC addresses. The board software will automatically change MAC addresses to **:** if done as above.

You need to do a speed test directly from the hub to rule out your own equipment/setup.

Thanks Tudor, 
I am using a standard UDM device (with multiple wired nanoAP's) with the latest official firmware @ 3.0.20.

Thanks in advance, appreciated.

Thanks for the info, I have tested all the equipment router side (i.e. my equipment) and all is well. I expected such as was always seeing the 500+mbps that I was expecting previously on my last service with virgin. All I have done is upgrade to the GiG1 service, replaced the hub (and placed again in modem mode) so would expect it to be the same but faster. Alas, it is not.

[RLipscomb]

also, app version is 7.4.156 .. sorry I missed that part of question 🙂

[Tudor]

Further thoughts. You only seem to have 4 upstream channels when you should have 6 (only 5 will show as there is a bug in the hub’s firmware that omits displaying the DOCSIS 3.1 channels). So looks like two upstreams are probably missing. 
Have you got DPI turned on? You could try an SSH connection to the UDM and take a look in /var/logs and see if anything is obvious and also run ‘journalctl’ from that session.
