Hi All - I just got an Airport Express set-up and it is working great with our iBook (1.42GHz), but less well with our PowerBook (1.67GHz). Download test show ~5Mbs for the iBook, but 1.4Mbs for the Powerbook. They are both 802.11g cards. Any thoughts? I'm not sure where to begin. I searched the forums, but got a ton of hits, read many, and didn't get anywhere. Incidently, I just trashed the /usr directory on the iBook (bonehead move...dont' ask), but I replaced it from the back-up drive...some links are broken, which I still need to fix. I only mention this on the off chance that it is related. Thanks.
