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:

Thanks for the private message @pjayuk, I've forwarded your details onto the area field manager to advise me further of any issues we may be experiencing in the local area, and to see if any follow up visit can be arranged.

I'll be back in touch if I have any movement on this

Kindest regards,

Thanks, David.

Sorry you're still experiencing issues @pjayuk

As soon as David hears back from the AFM on how we should proceed next, we will update you. 

Thanks for your patience.

Hi,

Did you receive a reply from the AFM? I’m still getting dropping upstream QAMs, this is from this morning:

Hi pjayuk,
Thank you for reaching back out to us, sorry to hear you are still facing slow upstream,  I have had a look at the account and cannot see any further information or updates, I have tried to run further checks however as you do have a 3rd party Router, please put ours back in Router mode, so we can run further checks?

Regards

Paul.

[pjayuk]

Hi Paul,

I don’t see how dropping upstream QAMs can be anything to do with my router. Surely a Virgin network problem? If they were solidly locked on 64 all the time and I was getting slow upstream speeds I would look at my equipment. They have all returned to 64 QAM tonight for the first time in a few days and speeds are normal, but who knows how long that will last?

Hi pjayuk,

You're absolutely right - any issues with your QAM would be caused by an external factor. However I'm pleased to hear that things seemed to improve for you on Thursday. How've things been since? Let us know if you still need help.

Thanks

Two upstream channels have dropped to 32 this morning.
