Broadband disconnecting regularly

Hi,

I have been having trouble with my connections since I have moved into my house a year or so ago. The main issue I am finding is that my iPads are regularly showing disconnection messages, requiring me to "try again". Sometimes they lose connection to the wifi and need to be manually reconnected. I'm getting the same issue with my Sony TV. I used to use Orbi for wifi and now I use the Virgin Wifi so I don't see it being the wifi side of things, but broadband disconnections, I am a network engineer so I would really appreciate help with the broadband side of things. I have set up a quality monitor that you can see here:

Post the power levels, Pre and PostRS errors and network log from the Hub.  Once done we can comment.

The BQM looks okay.

If it's only the wifi is disconnecting, it could be the VM's "Intelligent Wifi" is changing bands and channels, thus causing your devices to drop.  From reading on these Forums, the AP Roaming and Band Steering is not the best.

Also just curious why you don't use the Orbi's anymore?

I stopped using the orbis as I thought it might be those causing the issue so switched to the in built WiFi 6 with the intelligent WiFi mesh. But same issue with both so now I feel its more the broadband. Will post the other logs in a mo

Too many PostRS errors showing.  Power cycle the Hub and check the numbers, they should be zero and not rise quickly.

The Upstream profile is flapping around from one to another, so I suspect there is a circuit issue with noise or something.

The Downstream power is a tad high, but still in spec of -6 to +10.

You need to post the Upstream power levels to complete the picture, thanks.

If you wait here a day or two a VM Mod should pick this up and arrange a technician to sort it out.
