From the ifconfig(8) manpage:

: A WEP key will be either 5 or 13 characters (40 or 104 bits)
: depending of the local network and the capabilities of the
: adaptor.

State Changed
From-To: open->closed

The 108-bit key is understood to be the correct behavior.

Thanks, Ruslan.... however, I suppose that 5 or 13
characters refers to ASCII representations.  The number
of hex digits will differ.

Hmmm...  turns out that a better answer would have been
for me to (re-)read the 6-0 Release Notes...
particularly section 2.2.2.2. Network Interface Support.

Apparently: "Note in particular that WEP now requires
the wlan_wep module to be loaded (or compiled) into the
kernel."

All fine and good... but I'd be surprised if others
don't trip on this as well when 6.x gets more usage.

Oh...  Sorry about the lame subject line.  I hit the 
submit button before going back and "fixing" the Subject.

Thanks,
  - Christopher
