further, many routers have a function where you have to have a certain MAC address in order to logon. This is not a perfect layer of security, but it is yet another one that I think is worth it. However, WEP is fundamentally broken and should be avoided. Try using WAP, which is also somewhat broken, but much less so than WEP. WAP2 (isn't what they are calling it) is unbroken, as far as we know at least, though it isn't a completed spec nor is it supported by most hardware.
