Experience random periods of high packet loss, and loss of connection

We were reconnected to virgin on 16th August, and since then have experienced repeated drop outs, and bouts of high packet loss.  BQM graphs are here Share Live Graph

This morning the connection dropped for 40 minutes before becoming stable again.

Router stats are after rebooting this 15 minutes ago

Re: Experience random periods of high packet loss, and loss of connection

Your BQM link is not to the "Share Live Graph" link - it s to your login page - so we cant see anything.

You are missing the Up channels T error table and the network logs

Stats all look good as does the BQM - Except for a large "wobbly" between 11.00-12.00

What do the Network Logs report for that period?

Were you doing anything "unusual" in that period ?

Re: Experience random periods of high packet loss, and loss of connection

What were you doing at 11.00-12.00 any high usage. BQM looks ok-ish today one drop and a few packet losses at the top - - its not perfect. It really needs VM to look at the details. Someone should respond here soon

Re: Experience random periods of high packet loss, and loss of connection

Good morning @andyleadbetter

 

Welcome back to the forums and thank you for taking the time to post.

 

I am sorry to hear that you have had some issues with your services. 

 

How are things looking at the moment?  Is your BQM link still live? 

 

Kind regards,

Zak_M
