This is a cut n paste from an earlier post:
Whats your budget? You on cable or asdl?
Im no expert but our old O2 one died recently so I did some digging. Came across this and got one for about £90. There are different variants of the same thing for just router, asdl router, cable router but you should find them easy enough (they seem to vary from £50 – £90 depending):

Its range is at least twice of anything we had before, it’s dual band (for modern devices like an S3), its got 2 usb ports (for a printer and say a harddrive for backups / nas), guest networks, gigabit and usb3 (for faster backups), parental settings, …. and is a doddle to setup and use.
I’ll stand by it – if you’ve got 50 – 100 gbp to spend.You’ll need the asdl version.
