CRIO Wireless network issues

[DanInDC]

I am a first time FIRST mentor working with an "established" team, but pretty much everyone is a rookie, other mentors included.

We are trying to set up a network so that we can connect the classmate and a development laptop to the CRIO. We tried following the instructions, but they are confusing at best. Sometimes it refers to bridges sometimes routers sometimes radios. This is the equipment we have

CRIO
Gaming bridge (small black box from last year)
classmate netbook
development laptop
Linksys AP/Bridge

I've read a few other threads with similar questions, and think I have a good handle, but just want to clarify because I know I'll have trouble otherwise.

So it seems we no longer need the small black gaming bridge from last year. So we'll put the linksys into AP mode, set the ssid to our team number, set the WPA key to ####WPAKEY. The linksys device in AP mode connects directly to the CRIO via an ethernet cable(??). Then the classmate and development laptop connect to the AP via wireless connections. (??)

Then we'll have:
CRIO 10.XX.XX.2
classmate 10.XX.XX.5
development laptop 10.XX.XX.101

What about default gateways and all that? subnet masks?

Thanks for any help and clarification.
