Hang on here and somebody will be along shortly to help.
In the meantime, try giving the hub a break when you can, also if its inside a cabinet or closed space try to let it get air, as silly as this sounds at this time of year but do you have a little fan you can use to keep it cool to avoid it offlining. .
Also check if the any of the cables are loose and if so tighten or push them in.
Thank you for your response. The unit is currently on top of our TV cabinet, with plenty of airflow, granted, its getting some heavy usage at the moment. I've also unplugged the unit so it can cool down and checked all cables, which normally helps, not the best solution, as it means I have to wait around 10 to 15mins for it to re-boot. To be fair, the unit has performed well, nevertheless, I fear some componentry must be breaking down.
