Trouble Connecting With the Wi-Fi: Interfaces

I’m having a lot of trouble with making my “interfaces” directory. The instructions are very unclear on what configurations I should use for my interface. What should I write out? The site is below, and it’s Option 3

Did you see the link to this file:
https://github.com/DexterInd/BrickPi/blob/master/Image/interfaces.txt

It is exactly what you should write out; all you need to do is replace the SSID and the Password.

What file do I save it in after that on the Wordpad? Do I save it under Rich Text Format?

You need to rename it as interfaces (drop the “txt”).

It should be placed in the directory:
/etc/network/interfaces

Also, it sounds like yuo’re using microsoft wordpad. This will not work. Copy the file to your Pi, and edit it with nano:

sudo nano interfaces.txt
