Northampton NN1 High latency & 10-20% PKTLoss

Hi All,

Will be calling VM in the morning to note this.

Over the past week i've been struggling with packet loss in 10-20% range.

I'm a wired client with router in modem mode, and i've checked connection to WAN port with no issues. I'm now extremely confident that the issue is external to my equipment. i.e past my WAN port.

See BQM images below...

I'll also include modem logs.

Any thoughts?

This is likely to be the last straw with VM. The bandwidth is great, but jitter and latency is appauling. If this doesn't get fixed sometime soon, i'm going to jump ship to a higher availability ADSL ISP ASAP.
