Just a FYI: WEP is not secure, it's pretty easy to crack. MAC filtering won't save you either. People can spoof a MAC address that matches one of your machines by examining the packet traffic. If you want true security you need to use WPA2-PSK with a 63 character random string for the key, and AES encryption (it's better than TKIP from what I understand). This makes it impossible for someone to break into your network. A weak (short, non-random) WPA key is susceptible to a dictionary attack. WEP can be cracked within minutes. Here's some useful info about WiFi LAN security:

He says that an 8 character random string is enough to secure WPA, but I prefer the maximum security provided by 63 characters. There're a whole bunch of random key generators available to make your life easier, like
this one.
