Appreciate this is an old thread, but we have the same issue. After we upgraded from the regular fibre 72mb, to 150mb, it became incredibly unstable, even after the inital 2 week bedding in period. After a month or so sky agreed to swap the router, same issue persists... maybe not as regularly, but still happening. A few weeks later i installed a netgear gaming router, wifi was 99% more stable. Still not perfect, we had a drop today, but better. From never even looking at the router, to regularly rebooting it, now 'coping' with the odd blip, it is pretty poor. I suspect they use it as an up sell to the maintained wifi service to get extra cash from those who don't know better - that is something the agent offered me, which 'would resolve my issues'. Providing decent kit to customers would do that!
