Hi,

Thanks for the reply.

I've been through those checks and this is what I've found

- signal strength of the hub is -43. I plugged a range extender in next to it and the signal was up to -4 but the issue remained

- no appreciable network lag. The longest was around 70 milliseconds but there were loads of pings of 3 or 4 milliseconds.

- the same issue occurs on a different mobile device that's on a different network.

Tomorrow I'm visiting someone who has a superfast broadband connection so I'll try it from their place and report the findings back here.

I've tried uploading a video to this post but it fails. Any suggestions how to share it?
