You're missing out.....
The one I used, in a 2 story house covered almost the entire block! (as in street block, not single property block)
Got no real need for them myself. My Fritz! 7390 covers my small weatherboard 2br house easily and to give my mother internet through my connection I have a point to point link over the 80 odd metre distance.
One end is an Edimax 7303HPn v2.0 (got it cheap otherwise would have used a Ubiquiti of some sort) and the remote end is a TP-Link WR743ND v2 with a directional antenna (had these sitting here spare so may as well use them).
Mums usage is very minimal, just gmail and the odd image attachment plus a bit of reading on "The Conversation".
