Couple of questions about settings on Wireless

Hey everyone, just wanted to see how I should set up my wireless security on my AirPort Base Station. Also, what is the multicast rate? Any settings I should know about to get the best use of my base station?

I don't know what mulitcast rate is, but I wouldn't mess with it if you don't know what it is. Yes by all mean turn on your security, but make sure what ever type you use all of your hardware on the network supports it (for example PSPs can't use a WPA key). And I would turn the broadcast power all the way up to get maximum range.
