speed problem (mostly on upload)

Hello,

I have an issue with my speed. The download speed is dropping to anywhere between 100 and the usual 200 (not really an issue) and the upload speed has been dropping to 2-5 and below in the evenings (usual upload is 20). This started on Friday 23rd, but seemed to be fine on 25th, only to be bad again on 26th.

I set up a BQM to take a look and there is a lot of packet loss during the times I experience problems and latency spikes.
24th BQM
25th BQM
26th BQM
Live BQM 

I have checked the status page on my-vm and no faults are listed. I ran the test there and it tells me everything is fine. I have restarted the hub (hub 3), reset it to factory via the button and checked all the cables (unplugged and plugged in again). I have tested speeds on 3 computers in the house, all of which are wired and show the same lack of speed.

Here are my router status pages:

Re: speed problem (mostly on upload)

Your Downstream Power Levels are far too high and will need an engineer visit to put them right.

You can either phone in (08:00 is the best time) or wait on here for a few days (6 to 7 days average) until one of the VM Forum Staff comes along.

If you wait on here Do Not bump the thread it will put it further down the VM 'to do list'.

Re: speed problem (mostly on upload)

Thank you for the reply. I will wait for a staff member to respond.

Do you know why the power levels only make the connection unstable in the evenings? Or would that be something to ask the engineer?
