"Only we guarantee Wi-Fi in every room"
The comments here alone demonstrate that BT is overly exaggerating once again. WFi extenders have existed since the Internet came into our homes. BT is far from being the only company creating such equipment.
On the other hand, it seems that BT doesn't have the requisite experience to make a good product, unlike many other vendors who've gotten the tech down pat since last millennium.
Who'd've thought ? Oh, everybody. I see.
