Why would you take a really valuable & useful box like an AirMagnet Sensor, and waste it on just another router box?
There are dozens of cheap, easily available commodity routers convertabile to dd-wrt.
There are very few second hand expensive enterprise class wifi sniffers & jammers like these AirMagnets.
Why not use them for what they're designed for, and find out what's really going on around your own wireless environment.
Then your original question on how to get into these things and change the keys as Local Crypto Officer becomes far more relevant.
