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
