Hi FerretDragon,
Thank you for your post, we're sorry to hear that you've been having ongoing issues with your Hub 4 and connection in general.
I've been able to take a look at things from this end and can see that your connection was very bad on Monday and a lot of disconnections were logged. However since then, we can't see there have been any disconnections and everything is looking perfect from our end. All your levels are in the normal parameters.
How've things been since? Let us know if you are still having trouble.
Beth
