Continuing upstream connection drops (No. 2)

I posted a few weeks back about repeated service drops but was unable to post a BQM due to a firewall on external router.  I’m now getting them more than even and have solved the BQM so can include in my post.  I have since done a hard reset of the of the Hub 3 so starting new thread with new diagnostics:

Re: Continuing upstream connection drops (No. 2)

Hello

Bouncing or bumping the thread will not take the post to the top of the queue it has the opposite affect due to VM staff dealing with oldest un-answered posts first and can take several days to get back to you.

But on this occasion what I can do is too escalate this to be looked at by a VM staff member but still may take a few days.

Re: Continuing upstream connection drops (No. 2)

Thank you Mike, I appreciate the help.  Was not intending to jump the queue and I am fine to wait, simply that other threads are getting responses and my query was over 2 weeks ago with no indication it had even been seen.  Many thanks

Re: Continuing upstream connection drops (No. 2)

Good morning @NK212 

 

Thank you for your post, sorry it took a little while to respond.

 

I have taken a further look into your account from our end and as advised previously everything seems to be in spec. 

 

When you do experience these drop in connection, are they happening on all devices? 

 

Are you connected to both wired and using WiFi?

 

 

Kind regards,

Zak_M

Re: Continuing upstream connection drops (No. 2)

Good morning Zak,

 

Yes, drops affect all devices.  The hub is connected wired to a 3rd party router which provides the WiFi network, although I have also tried WiFi to the hub as well in the past with the same issues.  When the service drops, it can be seen on the BQM so is definitely a drop on service to the hub, not a WiFi issue as WiFi networks always stay active and connected.

 

Thanks
