No problem; WEP just sucks because there are 3 different ways to enter
WEP keys (hex, passphrase, and ascii) and two different auth methods
(open and shared) and there is _no_ way to distinguish any of them from
each other.  WPA fixes this because you can actually distinguish a WPA
hex key from a WPA passphrase, if entered correctly (WPA hex keys are 64
characters, passphrases are between 8 and 63 characters inclusive).  The
problem with WEP is that you can certainly have a passphrase that's the
same lenth as a hex key (26 characters), and I've seen many cases where
people are actually using a hex key as a WEP passphrase.
