VM staff members get to posts in order of latest post. So the more posts of stats, that everyone agrees are bad, puts you at the bottom of the queue. Just wait until they get to your post.

Hi Fawcett90, 

Thanks for your post and apologies to hear you've been having an issue with your connection since upgrading to the 1GB service. 

Once an upgrade has been done and a new Hub installed, it can take a little while for it to settle down on the network. Rebooting all the time can actually cause more issues. 

Looking at the Hub stats, things are looking fine in terms of the power levels and the pre-rs errors are nothing to worry about really. The main concern here is the post-rs errors. 

I can see you've already spoken to the teams and there is an engineer booked to come and check on things. 

Please let us know how things go and if you need any further support. 

Thanks,

Speeds are all over the place - sometimes from cab to router i get 1200mb - but most the time between 200-600mb - but its never a stable speed coming from the cab to the router.
i should hopefully be getting another engineer visit as the engineer last night was unable to resolve and passed onto a supervisor
