#28 WEP key does not accept dollar sign

WEP key does not accept dollar sign. Association
between Cisco Aironet 340 PcCard and Apple Airport
works well without WEP, but not with WEP. According to
Cisco, the Airport stores WEP keys in ASCII, so it's
mandatory to use a "$" (dollar) prefix before the
hexadecimal key. Freebase doesn't allow this.

Cisco provided an answer relative to this issue
(http://www.cisco.com/warp/public/102/wlan/mac-clients-
faq.html#Q7) :

Q. My Cisco Aironet clients associate to an Apple
Airport Base Station just fine without WEP, but not
with WEP. I've verified the keys, but they still won't
associate. What's the problem?
A. The Apple Airport uses Wired Equivalent Privacy
(WEP) keys entered in ASCII; the Cisco Aironet
products use hexadecimal. To set a WEP key on an
Airport in hex, use a $ symbol before the key (see
Apple TIL # 106250). To ensure that you're using the
correct key, check the Airport Base Station
Configurator.
