Slow upstream since 200 to 350 VOLT upgrade

[pjayuk]

Since my upgrade from 200 to 350 as part of the VOLT benefits my upstream speed has intermittently dropped from 36 mbps to around 5 mbps with QAM dropping to 16 on three or four channels. Downstream is rock solid. Prior to the ‘upgrade’ both upstream and downstream were rock solid.

Upstream went off a cliff at about 0940 this morning:

Router is in modem mode and all speed checks via wired connection. I have checked all cables and pinhole reset the router, to no avail.

Could someone from Virgin take a look at this, please?

You could check with Area faults on 0800 561 0061 or if you have a VM landline 150, as small local faults are not reported on the VM status pages.

Thanks, just tried that, but no fault reported. My upstream has now slowed to 2 mbps making it impossible to work.

I notice your hub is in modem mode as you are logged into 192.168.100.1

Have you also rebooted your 3rd party router as well as the hub?

Also just checking, you don't say which VM hub you have, but if it's less than the hub3 then it needs replacing as the older models don't support speeds of M350 and above.

Hi Dave,

Yes, I have the router in modem mode. I have rebooted the AirPort Extreme it is connected to, no change. Router is a Superhub 3.

Hi again @pjayuk 

You could try a factory reset. 

Keep the hub switched on and disconnect any ethernet connections, then push the reset button firmly with a paperclip or something similair. keep it pressed in for a full minute.

Wait around 10 minutes and it should revert to factory settings. You can now reconnect the ethernet cables.

If you previously changed your router password it won't work and you will have to use the one printed on the sticker on the router. You can always change it again by going into the settings

QAM just starting to increase a bit at 1450, just as I’m due to finish work for the day.

Thanks, Dave, already tried that yesterday and today at the height of my frustration over not being able to work. Made no difference, I’m afraid. Just wish someone from Virgin would come on the thread so they can take a look from their end.

QAM returned to normal levels now at 1510. Seems to follow the same pattern each day. The QAM falls and the upstream goes off a cliff edge during the day, approximately between 0940 and 1500, just when I need the upstream to work!
