I'm trying to set Airport Extreme as a wireless access point, but having some problems with it. My current setup is as follows: Time Capsule as the main router. Connected to my cable modem, and all computers connect wirelessly to Time Capsule. Two Airport Expresses connect wirelessly to Time Capsule. "Join a wireless network" and have selected "Allow Ethernet Clients" I want to have Airport Extreme do the same thing that Airport Expresses are doing, and have it connect wirelessly to Time Capsule. I have some ethernet required devices that need to be in another room. Can this be done? I set Airport Extreme exactly same as Airport Express, but do not see "Allow Ethernet Clients" checkbox. Any workarounds? Thanks.
