Having decided that the state of affairs with the latest BT Home Hub software version was completely unacceptable, I decided it would make most sense to downgrade the software version back to 6.2.2.6.
I headed off to the BT website to find the recovery software, and downgraded using the software recovery utility. I also made entirely certain that I changed the configuration so that the automatic update would no longer happen, and that BT cannot update my software remotely.
If you are interested in downgrading your software, you should take a look here. In case BT update the firmware updater to use the latest version and it becomes inescapable, here are the direct links:
Much better.
