Update....
The PC is upstairs and the HomeHub downstairs so when the wireless disconnected during uploads there was something else I was missing. I turns out that when uploading large (well... over a few meg!!) files the HomeHub actually reboots. As in a full power on/off cycle!
WTF.
I only found this out the other day when uploading a Forza 3 movie on the Xbox and saw the hub reboot. I was gobsmacked. A quick google showed others with the same problem and conversations with BT have resulted in the following excuses; 1) its a security feature, it only happens when uploading with no download activity 2) its a fault with the firmware or 3) its being fixed in the July update.
As its now October I didnt get excuse 3. I got a modified version i.e. it will be fixed next month. I was about to tell them to shove it but he didnt deny the issue, he went on to say its affecting a large number of people and they're genuinely working on the problem.
In the meantime I can upload to Flickr for example of I have an active download at the same time (Internet radio would work) but I'm pretty screwed trying to upload Xbox content unless I trail a cable accross the lounge - its only fails on the wireless apparently.
