General Wireless Network Security

Howdy,

Because I got a new computer recently I have been reviewing security stuff including my at home wireless network.

I use a Belkin N150 "Enhanced Wireless Router" I have WPA2 enabled and always figured no one could get on my network because of this.
looking at my client list I saw 8 users on my network, got me thinking about wireless security. looked on the forum and maybe I just missed it but I couldn't find a general wireless network security post.

I have sense blocked the alien MAC addresses and will be allowing them back as my roomates complain and then setting up a list of approved MAC addresses.

Any advice on what level of security is actually secure?
please point me to any easy to read for very novice users tutorials on the subject.

Thanks,
MarkTex

 

wpa2 and a mac filter is all you can really do for a home network.
