for what you ask. Myself I just enable MAC filtering to keep out any onlookers. It's enough for me.
I cannot figure out, for the life of me, how to get the WEP encryption to work with windows XP. I'm using a Thinkpad T42. I type in the password, and it generates the numbers, but when I plug them into the notebook, it doesn't seem to work.

If I have not given enough info, please let me know.
