I have used many different makes of modem/routers since first getting broadband with most working OK but some were better than others for stability of connection and range. I now have BT Infinity but found the supplied BT router pretty awful.
Apart from poor range whenever a laptop or iPad went into sleep mode when woken it would not be able to access the network again until I rebooted the router!
A few months ago I fitted a Draytek 2830, recommended by a pal in the Telecoms business, he uses them all the time. Probably overkill in terms of capability but it is rock solid with a tremendous range.
Draytek also market the Vigor 2850n which is a vDSL modem/router meaning you can replace both the BT vDSL modem and BT's router with the one unit. I fitted one last Saturday for a friend who was suffering weak signal in parts of their large house. It cured the problem.
They are not the cheapest but I have been impressed!
