Topic: Octoprint setup on Raspberry Pi missing Wifi Config

This is the closest forum I could find for my problem.

I am setting up a Raspberry Pi B+ with Octoprint to run my printer. I got a kit that came with a compatible wifi dongle. I am able to load Octopi on my Pi, and get Octoprint to run with an ethernet cable (I have yet to actually hook the printer up and configure it because...). My desktop has no wifi config icon on it. In fact, there is nothing but the one main icon. Am missing something when I am unpacking the Octopi image? I am using the newest compiled image available.

I have tried using the command line to configure my wifi, without success. Admittedly, I know very little about linux programming. I am able to follow instructions, just none of them have worked for me.

I have watched several videos on how to configure the wifi. So there is no wifi config on my desktop, when I click on the network icon in the upper left nothing happens. When I right click, a window comes up that looks nothing like any of the examples I have seen. When I put in the Pi IP and my Router IP it does not connect.

I feel like I am missing something simple, but I cannot for the life of me figure it out.

Any help would be appreciated.

Re: Octoprint setup on Raspberry Pi missing Wifi Config

I just had to set this up. Let me try to find the bit that worked for me.

[EDIT]
Found it here: http://www.tested.com/tech/3d-printing/ … ng-octopi/

"Connecting the Pi to my Wi-Fi network was the only tricky part of the configuration. I found that most of the guides to configuring Wi-Fi on OctoPi were overly complicated. At the end of the day, all I had to do to get Wi-Fi working was open the /etc/network/interfaces file with nano using the following command "sudo nano /etc/network/interfaces" and then add the following lines on a new line under "iface wlan0 inet dhcp"

wpa-ssid "SSID NAME HERE"

wpa-psk "WPA PASSWORD HERE"

After that I rebooted the machine using the command "sudo shutdown now -r", and unplugged the Ethernet cable. After the Pi rebooted, I was able to connect to it using the same address, http://octopi-local/. The only difference is that I was connected over Wi-Fi instead of a cable."

On mine when I opened up the interfaces file, it had something like "iface wlan0 inet auto" so I just changed it to "iface wlan0 inet dhcp" and added the following lines right underneath:
wpa-ssid "SSID NAME HERE"
wpa-psk "WPA PASSWORD HERE"

After that I did a restart and it worked right away. Good luck!

Re: Octoprint setup on Raspberry Pi missing Wifi Config

Thank you for the help. Turned out I used the octoprint.network file.  When I was double-clicking to open it, the character-returned lines were not recognized. The whole file looked like one big line of code. When I opened it in Wordpad it was formatted correctly, and all I had to do was uncomment the correct lines and put my wifi information in. This connected to my network at home, but I frequently take my printer out to events (at least a monthly 3d printer meetup). I haven't checked yet, but is there a way to configure so that it will detect networks? or does it always have to be hard coded in?

Now I am on to wiring the PI into board. This should be fun...
