Loggin into a WEP enable home network

[Terry R. Grier]

Hello all.

I am having to work out of a friends house for a couple of weeks.  I am
connected to his router via a direct cable but his router is WEP
enable.  However.. as a 3 week old linux user.... I do not know where to
look to enter this code.
or is it the other way around...? ...
Can someone assist.  Is is an XP user and does not know either.

Thank you
T
