How could I change the wifi setup on my Octopi?

[ardu1]

Hello together,

I bought today an Octopi together with a MK3s+. This are the first steps with this system. The Octopi was running with wifi were I bought it. Now at home I tried to connect the Octopi with my wifi. I connected the Octopi to my rooter and I could log in Octoprint (version 1.6.1). But there I didn't find a menu to change the wifi setting. I think I must change it on the system of the pi? Next I tried to connect the Octopi with the terminal of my Mac. I could reach the Octopi, but I do not know the password, "raspberry" does not work. Has anyone an idea to change the setup and could help me?

Thanks and best regards!

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

This will help with the WiFi setup:

WiFi setup and troubleshooting

A number of people who have followed the instructions for setting up OctoPi on your Raspberry Pi experience problems getting connected to WiFi. This thread is intended to detail a couple of common problems people have experienced and things to try to resolve them. This page assumes that your WiFi network is up and working and that other devices are able to connect to it without a problem. We are also assuming that you have already successfully downloaded the OctoPi image and "burned" it on to y…

As for the password change, this one will help:

Forgotten username and password to SSH into Pi

Take the SD card out, put it in a card reader. Create a file octopi-password.txt on it, containing a new password as it's only line. Unmount, boot, login with the new password. Put that in ages ago for cases liked this and for easier provisioning. Should hopefully still work.

Thanks for your answers!

I did this:

Opening the file octopi-spa-supplicant.txt

Than uncomment this lines

WPA/WPA2 secured
network={
ssid="mywlan"
psk="xxxxxxxxxxxxxxxxxxx"
}

Than saving -but I does not see the Octopi in my rooter ?

Have you selected the correct country?

Good morning,

yes, Germany. Is it correct to type all with quotation marks?

What I'm wondering, were are the data of the first wifi setting? I thought I only have to overwrite the ssid and the password?

I found the solution:

1. I connected with Mac terminal with ssh pi@ip-adress and the normal password for the pi user.
   The first time I tried to connect I used the wrong user, I tried it with "root" - that was my mistake.
2. Than I opened the config menu and write down my wifi data
3. Now I could use the pi in my wifi.

Wow now after some minutes I could start Octoprint!

Thanks for all!
