intermittent loss of connection

Really losing my patience with VM.  When you call for help you have to ring twice now as first call is all automated and all I get is reboot your Hub.  When you do s peak with a human they are useless!!  I keep asking them to look at the HUB 3 logs and see the errors and they keep coming up with nonsensical excuses.  I have been in IT for over 25 years and they are the worse!.  I am adding my Network logs etc to see if anyone can help.

Unfortunately the remote call centre staff have no technical training beyond reading a script on a screen. 

Your network log alone doesn't tell the full story. Please post the downstream and upstream logs as well. 

It would also be very useful if you could set up a free BQM and post a link here.

The downstream looks entirely normal.  Where is the upstream data?  Post a link to the BQM, which will show any dropouts

Hi there @Irichar0

 

Thank you so much for your post and I am so sorry to see you are facing these issues with your connection. 

 

I have double checked the Hub on our side and everything appears to be in spec, so we cannot see what could be causing this issue. Can I ask if you are experiencing this loss of connection on wired as well as WiFi devices? 

 

Are you able to do as advised by @jpeg1 and provide us with a BQM? Can you set this up and let it run for 24-48 hours then post the results so we can get a more in depth look into these disconnects?
