The Hub Two router is of inferior quality with regard to wifi range. After being sent a replacement router which would not even authenticate. No other router is available from them. It was cheekily suggested that I fit an extender and or alter router settings. A potential customer is unaware of these pitfalls and the situation should be rectified immediately.
My eventual solution is that I have returned to my original supplier EE and they are kindly paying for my early termination fee up to £50. The fee is £22 but I even get to keep the £28 change!
