MAc address filtering is not as secure as you think, it is very easy to capture a mac address from a data packet and then clone that mac address to enable access.
If you have a linksys router, i would suggest that you set up WPA on it as it is a lot more secure than WEP. It is suprisingly easy to crack WEP as roycruse. We were shown in our lectures at university just how easy it is!!! as soon as i got home i stopped using WEP and used WPA atraight away.
Ny probs let me know
