I have had the hub for a few days myself, and have to agree with your comments. I have a three-storey house and it reaches all floors from the ground floor up, no deadspots and decent throughput in the bedrooms at the top.
I moved house three weeks ago and cannot set up my new hub!
i have phoned four times. Each Tim over an hour.
i am a very disabled pensioner and cannot move about the back of my TV and talk talk box!
i have had no television for three weeks but you are still charging me full money.
can you please send an engineer to set it up!
