im aware, it was worse after the engineer left last night as before he came it was only the 1 channel, But he thinks theres issues in the cab and had to leave it for now and escalated to his supervisor - hopefully he might be coming out to me today, But ive not heard anything 😞 im just sat in limbo at the min paying full price for a service im not getting

Well you aren't getting the min guaranteed speed so VM need to do something about it.

im hoping one the admins will reach out to me soon so we can get something sorted - even worse when im working from home 😕

so an update, engineers been out again and swapped out the router, and still have the same issues with speeds not hitting above 480mb, when should be 1gb, cables have been checked and no errors could be found, so they are now reaching out to networks.

Since the engineer left i have noticed im only getting 20 channels on docsis 3.0 and 1 on Docsis 3.1

Thanks for your posts and updates, Fawcett90,

 

How has the service been since your post? I can see on a similar post it's back to 32 channels. Let us know how it goes.

 

Cheers,
