Much to my surprise, the Airport card refused to login to the access point when I used my set password; instead I had to use the 128bit hex key from the page of the administration Tool on the Netgear router. In the Apple Airport dialog box, you do not select "Password" from the drop down, you select "128bit-hex" and after doing that, it works flawlessly.
Took me some time to find this one, but after finding it, I must say, that I am most pleased with the product; it is definitely worth the money, at least for me.
