Give me more range, not more speed!!
Stop making wifi faster and work out a way of improving the range!!
Or maybe have a two pronged approach, better coverage from fewer routers/access points for home users and fast as hell with a gazillion access points required for businesses that want to get rid of cabling to the desks.
Why do I need faster wifi? It's already faster than most devices can read data off the storage anyway (at least for the majority of home users). Even my modest 4 bedroom house has required a mesh system to get decent signal on the top floor (3 storey town house here) and even then I needed to play around with positioning of the main router and the satellite to stop the wireless backhaul from dropping out every so often. The internet connection comes in at the front of the house on the ground floor and wireless signal on the top floor at the back of the house was borderline with most routers (no idea what the BT one is like as it's still in the box with the shrink wrap on it).
Just glad I never connected a landline phone up when we moved here as if I wanted to carry on using the landline I'd have to get the router out the box and either use their router or double NAT as it can't be put into modem only mode. Personally I don't think that they should be allowed to do that but I can't be arsed arguing with them as I never use the landline anyway.
