I am using a Raspberry Pi 3B with PiOS and I followed these tutorials for setting up a raspberry pi as a WAP and enabling MAC address filtering... https://learn.sparkfun.com/tutorials/setting-up-a-raspberry-pi-3-as-an-access-point/all and https://forums.raspberrypi.com/viewtopic.php?t=200798
I currently have gotten the MAC address filter to work, so that when my whitelist.txt file is empty, nothing can connect to the access point. When I update the whitelist.txt with the MAC addresses I want to be allowed, those devices can connect. I have one question however, after adding the MAC addresses, it won't allow me to connect my devices until I reboot the Pi. It's not a huge deal (usually takes a minute or so), but I want to know if there's any way to not have to reboot the Pi to allow my devices to connect once their MAC addresses have been added and saved. I am relatively new to Linux so I know that there is most likely an easy answer that I just have no clue about.
