Setup WIFI in Raspbian Stretch Lite

In order to configure WIFI in Raspbian Stretch, you will need to connect to your Pi via SSH (see the KB Article HERE) or attach a keyboard and monitor to your Pi (see the KB Article HERE).      

There are a couple of options to configure WIFI in Stretch.

Type in the SSID of your wireless network hit <Tab> then hit <Enter>.

Remove the line with the clear text password by getting to the beginning of the line and type <Control>+k. Then type <Control>+x and answer "y" <Enter> to save the file.

In order to use the newly configured WIFI, you will need to enter the following:
