Hi
I have recently upgraded from Ultimate Oomph to Ultimate Volt With Gig1 available in my area
The Hub 4 Self Install kit arrived and was installed on Saturday evening (04/12)
I have noticed that the upload and download speeds are consistent with M600 and are not going any higher than 644.91mbps Down / 42.09 mbps Up
Having a look at the Downstream/Upstream channels in the Router Logs of the Hub 4 , There is only 1 DOCSIS 3.1 Downstream channel and There is no DOCSIS 3.1 Upstream channels
DOCSIS 3.0 However has 31 Downstream and 4 Upstream - is this correct?
I have today powered off and on Hub 4 since it was installed on Saturday, Thinking perhaps due to the day and time of install may of delayed the changes on the line for Gig1 but the speed remains the same.
If anyone could please advise me?
Thanks,
R

No, didn’t have that on the old hub 3 or on this hub 4 when it was delivered

I'd suggest it may be worth an engineer visit to correct the power levels at the cabinet.

Are you saying the power levels are too high or low? Not sure what I would present to VM to send out the relevant engineer?

Some of them are out of spec (-6 to +10 is the 'in spec' range). I've highlighted the values below:

If you can wait a few days a VM staff member will respond to this thread.

Hi @starlir,
Welcome back to our Community Forums! Thank you for your post, and I'm sorry to hear that you're experiencing some ongoing issues with your connection!
I was able to locate your account and run some basic checks for you. I can see some issues with your downstream power levels, which will require for a technician visit as we're unable to rectify this issue remotely. In order to have this arranged, I will need to confirm a few details with you over Private Message. Please keep an eye out for a purple envelope at the top right corner of your Forum page. I will be in touch soon.
Thank you.

Engineer called Friday afternoon, 6db attenuator fitted, line checked for noise and none found. All channels now in spec and inbuilt router speed check showing 928Mbps download. As such issue resolved. Many thanks for all the help on this issue.
