Slow upstream since 200 to 350 VOLT upgrade

Dialled in

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:

Just to document this, 10.25 am all upstream QAM go to 16, upstream completely dead.

Hi Pjayuk, 

Thank you for your reply, I have had a look at your account remotely and checked your power levels, I can see you require a tech, I will pop you over a PM and we can go from there 😄

Thanks Zoie,

A tech visited yesterday and fitted an attenuator. This didn’t fix the problem so he is coming back tomorrow to replace the modem.

Hi Pjayuk,

Thank you for messaging with me, please keep us posted with your visit 😄

Will do. I also noticed this odd-looking wiring  adjacent to my neighbour’s balcony, and into which my cable runs. There is a piece of cut co-ax cable just hanging there and the blue box. I will alert the engineer and see if he can get into next door’s flat to investigate.

Just chiming in because I am in a similar area of North London and also experiencing the same problem: https://community.virginmedia.com/t5/Speed/Packet-loss-suddenly-started-about-ten-days-ago/m-p/48667...

That looks horrible. I haven't had any packet loss since 4 am this morning, meaning that I could work normally today for the first time since the Friday before last. There was a fault recorded on the Virgin fault line when I rang it this morning for the first time since this started, and when I rang the tech who was going to replace my modem he said he'd been to another person local to me on Saturday who had the same problem, hence he'd called in a network fault in the area. I've put the modem replacement on hold for the moment and will continue monitoring my connection to see if I get any more packet loss.

I’m getting packet loss and slow upstream at 8 am this morning again, so this is not fixed.
