Minix mini PCs

Having used the terminal to list the network devices with ‘ip link show’, i do now see:

2: wlan0 <BROADCAST, MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 40:e2:.....

I tried to enable it with:

sudo ifconfig wlan0 up

but got this error: SIOCSIFFLAGS: operation not permitted
