1. Update Mac Airport software to 3.1 (06/19/03)
2. Update Netgear MR814v2 firmware to 5.0.1 (release date 05/22/03) from netgear.com
I use the default MR814v2 setting and only add a WEP. And the Airport Extreme uses the generated key as the password. (Mac needs the"$" in front of the key in the password field.)
Enjoy.
