Currently I have 1 AirPort Extreme as the base station for connecting the Internet and 2 AirPort Express to extend the network so that I can have Internet access wherever I go in my house. However, I don't think my current setting is optimized for my setup. I want to know if there are any great tools out there? And I use "Participate in a WDS network" as my wireless mode. Previously I use Stumbler for monitoring the network signal. Any others?
