I have a cheap laptop with a cheap integrated wireless card.

No matter what I try, I cannot get it to work with a secured wireless connection.

The only way for it to connect is to leave my wireless connection open.

This lets all of my neighbors in on my connection though.

I first tried to use the Access Restrictions feature, but found that only blocked the Internet.

People could still connect to my web connection.

Then I discovered my Linksys WRT54G router has a Wireless MAC Filter feature.
