Wifi not coming up on raspberry pi

#1

Hi,

I just booted a new copy of the 1.5 RancherOS on my raspberry pi 3. I installed a wifi config like this one:
#cloud-config
rancher:
network:
interfaces:
wlan0:
wifi_network: network1
wifi_networks:
network1:
ssid: xxxxxxxxxx
psk: xxxxxxxxxxx
scan_ssid: 1

…and then merged it by doing " sudo ros config merge -i my_file.yaml"

After rebooting, I did an “ifconfig” and the wifi port is simply not shown.

Any ideas what I might be doing wrong?

Thanks
