Hello
Recently upgraded from 600 to Gig1. Download speeds are perfect (only limited by the ethernet port) but upload is about half of what I was getting on 600 - around 20 mbps. I have noticed that the upstream modulation is at 16QAM.
Is it possible for someone at VM to take a look? Appreciate your help.

Thank you for your response. Interestingly the QAM figures are back to 64 but I am still getting slower than expected upload ~30mbps. Here are the current stats which look OK to me and when I get a second later I'll do a full reset.

Pretty sure the log errors are just where I was rebooting to get the Gig1 config after upgrading on Friday 🙂

Here you go! Overall connection working well, just seems to be the upload speeds still. A couple of tests have got to the full 50 mbps.

I have spoken to second line support, after waiting 1.5 hours and being transferred to 3 different people, to be told basically Virgin don't care about what upload speed you are getting it's not guaranteed and that there is no problem on my line.
Thing is, I have been told all upstream channels should be 64QAM, I have 1-2 channels at a time that are dropping down to 32QAM. Although second line support told me this is expected behaviour.... It was not like this when first installed so I find it hard to believe this is expected.
I have reset, tried different cables, devices, ensured the coax cables are connected correctly, tried with and without the attenuator fitted by an engineer for my old Hub 3. Still the same issues.

Sorry to hear that! Yeah I would have thought it reducing means there is some kind of noise on the line which could be investigated.
Today mine seems to be consistently working and the graph looks fine., I'll post back if I have further issues
Speedtest by Ookla - The Global Broadband Speed Test
I assume there are no updates on being able to register for the Hub 5? Would be great to use the full bandwidth via the 2.5g port.

Getting a similar issue since I was upgraded from 200 to 350 as part of the VOLT benefits. My downstream is rock solid at all times, but the the upstream QAM gradually drops during the morning to 16 on all channels, giving me approximately 5 mbps instead of 36 mbps. Follows the same pattern every day. Downstream and upstream were rock solid 24/7 before the upgrade.
