I love my HomeHub 6, never had an issue with it. It works flawlessly, I also split my SSIDs, the range is great too
At the time my thoughts were something along the lines of "this sounds so bad I'm not even going to waste a tenner on the postage".
I might give it a shot.
But, if anyone has any other suggestions feel free
I actually stopped using a custom router when I got my smarthub, it had better range.
