Generally I find wireless bridges and repeaters to use their own standards regardless of what they say they do, and Cisco are not known for playing especially well with others (they have a large share of the commercial big boy network market and very much use that position). Even when it does work it is not without issues either, for my money unless you really need a mesh network of sorts I would probably just set up a second access point and run a cable or use ethernet over powerline or something.
Also wireless N has been available for years now, wireless AC (the one after it) is probably years old as well at this point. Wireless A (an old standard) is a very strange thing indeed if you are used to the home stuff.
