I've noticed that every time the rb5 boots, the mac address for wlan0 interface changes. This is inconvenient, because I can't set the network router to reserve an IP address for it. Every time it boots, i have to use the adb shell to check what IP address ended up being assigned if i want to stream video or ssh to use vio and voa clients.
I saw some forums like this one that said to change /etc/NetworkManager/NetworkManager.conf, but there's is no network manager directory in /etc directory.
I tried creating /etc/NetworkManager/conf.d directory and adding a file there with the contents:
[device]
match-device=interface-name:wlan0
wifi.scan-rand-mac-address=no
but that didn't help.
Any ideas for how to use a constant mac address?
