Importance of reading manual pages (wireless)

I had some difficulty configuring wireless at Georgia Tech for OpenBSD, but it was only because of my failure to read the manual pages carefully.

Under the nwkey entry of ifconfig(8), "The key can either be a string, a series of hexadecimal digits (preceded by '0x')..." (emphasis mine). Obviously, if there is no '0x', then ifconfig assumes your WEP key is a string. In our school's case, the WEP key is hexadecimal.
