Area 22 Leeds - High latency, dropped packets and poor BQM

Until approx 2 weeks ago my connection at home was spot on but since approx 27th November my connection has been erratic with dropped packets and high and variable pings.

This is what I have tried

  • I have reset the router a few times.
  • Switched to modem mode and tested - no obvious difference

Here is the live BQM. The red blocks are where I am testing modem mode (which made no obvious difference).

My BQM 

Hope someone can help. Literally just signed a new contract with virigin and within a day or two the connection has gone downhill.

Here are my status data (router reset approx 1 hour ago):

Re: Area 22 Leeds - High latency, dropped packets and poor BQM

All your Downstream Power Levels are too high.

This will need an engineer to put right.

You can either call in (08:00 is the best time) or wait on here for a few days (6 to 10 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'.
