FYI MAC filtering really down't add much to your security as many WiFi scanning programs (inSSider, etc. ) tell you the MAC address of connected devices meaning that all an intruder has to do is clone a connected MAC address and then they can try and hack into your network. Best most people can do is a stong
If inSSider[or any other tool] can check the MAC address of my devices even if they're not connected to my[main] network, that would be something new to me. They'd have to get into my home and hardwire a PC to my router before they can even try to screw me up.
I also use Amped Wireless WiFi analytics ( runs on Android tablet) to check on nearby WiFi channels so I can pick the least used channel. In addition to the SSID, channel of the AP, it also gives me the AP's MAC address. Another App, Fing also provides lots of interesting information about networks and attached devices.
My point is that if you have WiFi turned on it is possible to quickly determine MAC addresses and private IP ranges. The added security a MAC address table gives you may not outweigh the trouble of keeping the table up to date as many devices have three or more MAC addresses (2.4Mhz, 5 Mhz, and Ethernet ).
Also if you are using MAC addresses to set up internet restrictions for your family, download Technitium MAC Address Changer and see how trivial a task it is to change a PCs MAC address making it possible any user to use another MAC address including yours.
For those of you that have an academic interest on how to hack a wireless network I suggest that you read the article linked below on Small Network Builders. In the first page of this article the author basically states that MAC address filitering is almost worthless as a security measure and shows you an example of why.www.smallnetbuilder.com/wireless/wirele ... -wpa2-2012
