How would this be done in the new Airport utility? With Airport Express?
Will this work with Airport Express 802.11(n) 1st Generation?
Which wireless mode corresponds to a roaming network setup? With it set to either "Join" or "Extend" and the network configuration the same as the primary base station, then when I connected, I was just getting the self-assigned IP address and wasn't able to connect to the internet. I have ethernet run from the Extreme which is the primary to the ethernet port on the Express.
