Speed dropping drastically many times a day

We are on the M200 broadband package and have been suffering multiple drop outs daily for a few months. There is no local problem reported in service status though a lot of out neighbours are having the same problem. My download speed can drop from 200 to 0.2 Mbps at different times of day. There is no pattern, just that it's bound to happen every day.

I've followed the rebooting, resetting advice many times and it hasn't helped. I now have to keep my phone handy in order to tether my mac to it when it drops out at critical times while working.

I will try and attach the requested log files in another message as every time I try to post this it says "correct highlighted errors and try again" ...there is nothing highlighted.

 
 

 

Thanks.

Your Downstream Power Levels individually are all within spec but, the differential between the lowest at +1.0dBmV and the highest at +5.9dBmv is too great.

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 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'.
