Hi there,
I've just read your thread with interest as we are experiencing similar issues to yourself.
Out of interest have you now managed to rectify the problems?
We switched from BT in March for a supposedly better service, but have had nothing but problems since.
My kids constantly loose connection when playing online and my wife has had issues when working from home.
We too are using the Hub 3.0. Checked all the connections multiple times and everything is secure, rebooted etc but still experiencing the same issues.
Will setup a BQM to start with and see what that tells us.
