Need advice with OS X networking

Hello people,

I have a WPA-key for my wireless network which linksys creates automatically, but when I bring home my work iMac, AirPort can't seem log on. When I turn on Airport Exress, and try logging in the key (asks for password) under 40-hex, 40-ascii, 128-hex or 128-ascii, or LEAP, it didn't work and can't seem to log onto the network. Are Mac's just not compatible with WPA keys? (I have OSX Tiger loaded on my iMac)

Please help, if you can.

Any chance you also have hardware address security enabled?

The 5 choices you listed are for WEP access - and LEAP - which is an older authentication mechanism. There should be a choice for WPA Personal in the drop down menu. See these screenshots
