Hi VM

We've had trouble free service from VM for a long time with a brilliant 100mb service.  But this week speed has dropped to 20-30mb and this evening I'm seeing anything between 1-20mb (on a wired connection).

Router has been restarted but makes no difference.  

Status as follows...

Should add that I'm in Aylesbury (area 22).  VM status reports no issues.
