MAC filtering for AP

[joshbgosh10592]

Hi there! First of all, this is awesome, and thank you!
I'm wondering if there's a way to implement MAC filtering so that only certain devices could connect to it. My phone tends to automatically connect to "attwifi" which causes connection issues with my phone. Now, if the AP has MAC filtering, my phone would just be rejected and I wouldn't have this problem.

I did try MAC filtering in the past, but unfortunately without success. :(
