Since i own such a magnificent little device as the raspberry pi 3 i like to profit from the built in wifi module.
As i tend to do such things not every day let’s write down the needed steps for the wifi config.
There is this file
/etc/network/interfaces where we can adjust the basic network config.
We have to change the wlan0 config from
dhcp in order to get automatic dhcp offers from the router.
sudo vim /etc/network/interfaces
There is a file mentioned in the
/etc/network/interfaces where we can put the config in:
Open this file with vim/nano and add your ssid and password:
sudo vim /etc/wpa_supplicant/wpa_supplicant.conf
and insert these lines at the bottom of the file:
last step if the config is not picked up automatically is to restart the wlan0 interface:
sudo ifdown wlan0
and enable it again:
sudo ifup wlan0
now you should be able to get a dhcp offer.
Look it up with
ifconfig and watch after wlan0
