Hub 3.0 keeps losing connection

[bn37qp]

Recently my Hub 3.0 has been intermittently losing connection. The dropout can last from a few minutes up to 30 minutes at a time. During a downtime, both wired and wireless connections are affected, and using different computers. I've changed cables, and used different ports on the hub, but the issue remains.

I'm fairly certain that it is the hub which is the problem, and wonder whether I qualify for an upgrade to a newer model.

Nothing like an AI-generated response from a brand new forum account.

You will only get a replacement Hub if the one you have is faulty and then there is a strong possibility that you will just get an old refurbished Hub3.

My be a fault on the Network connection can you do this...

Then… Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again). If character limits are “exceeded” - just do two posts

Also, .......If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. Click the lower link (Share Live Graph) then, click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

I've just added the details you asked for.

I'll look into the offline BQM.

[Cardiffman282]

Stats look good to me. 

[Client62]

During the long disconnections are you seeing any change in the lights on the front of the Hub ?

[jbrennand]

As said... stats look ok.

lets see the BQM asap.
