Apple AirPort Security Key Primer

A friend and colleague wrote asking for some tips as part of a
presentation at a user group about a recent trip we all took (Geek
Cruises' MacMania conference), and I thought it was worth sharing
these Apple items.

When you're setting up an AirPort network that has mixed platforms,
Macs and PCs, and using either the AirPort Base Station or another
company's base station, you'll find yourself frustrated when you try
to apply security.

AirPort's built-in security system, called WEP, works in a different
way under the Mac OS and other systems.

On the Mac, you type in a short phrase as your password. On other
systems and on non-Apple base stations, you enter a several digit
hexadecimal code. For the shorter version of WEP, called 40, 56, or
64-bit (it's all identical), you enter five 2-digit hex numbers or a
total of ten characters (like 1E 2B 3C 4F AA). For the longer WEP
security key, 128 bits, you enter 14 hex numbers or 28 characters!

The trick is that to use the hexadecimal key with an Apple AirPort
Card, you must enter a dollar-sign before the hex number, like

$1E2B3C4FAA

Likewise, if you have a PC client that wants to connect to an Apple
AirPort Base Station, you need to determine its hex key by using the
AirPort Admin Utility. Run the utility, connect to the base station,
and with the older admin utility, select Network Equivalent Password
from one of the menus; with the newer admin utility, click the
Password icon at the top of the configuration window.

Enter that hex key in the PC client *without* the dollar sign in
front of it, or just

1E2B3C4FAA

If you are on a system that's using 128-bit WEP and your Macintosh
won't join no matter what you try, you probably have an old AirPort
card that only supported shorter keys. Apple's free AirPort software
update will change the firmware in your card so that it now supports
128-bit keys. Go to Apple's site, click Support, and follow the links
for software to download the latest release of AirPort. You can also
use the Software Update control panel or system preference.

There's one other case in which you might need to enter something
slightly different. Some PC systems use a passphrase like Apple's,
but it doesn't work identically. If you use a passphrase on any card
except Apple's AirPort, then to make it work with a Mac, you enter
the passphrase in quotation marks when the password is asked for.

So, for instance, if a PC user enters

gobblegoop

as their password, a Mac owner with an AirPort card enters

"gobblegoop"
