Download clean version wpa_supplicant.txt for octopi

Be sure to use an appropriate text editor. For most WiFi networks, you'll edit the section that looks like this:. Uncomment the 4 lines which have a single front of them by deleting the do not delete any spaces after the , then enter your WiFi network SSID your network's "name" and the password in the indicated places. Note that the SSID and password are case sensitive. A common problem when cutting and pasting this information is accidentally including leading or trailing spaces which are not part of the SSID or password.

For a network named JoesWiFi with a password of , it should look like this:. In OctoPi 0. Scroll to near the bottom of the file and find the section that begins with " Uncomment the country your Pi is in If you are in some country other than the UK, comment out the United Kingdom line by putting a in front of it, then remove the from in front of the country you are in do NOT remove the from the middle of the line. If your country is not in the list, follow the link provided in the file to find the complete list, and create a new line for your country.

For example, if you are in Switzerland, you would scroll down the page to find that the 2 letter code is "CH", and create a new line that looks like this:. You'll need to to some additional changes or your Pi won't be able to find your network after all! Save the changes and exit the text editor. Do not simply yank the SD card from the reader slot.

Make sure the Pi is powered down, and then install the SD card in your Pi and boot it up by turning on the power to the Pi. Note that the first boot may take some time: be patient. Uncomment the 3 lines which have a single front of them by deleting the do not delete any spaces after the , then enter your WiFi network SSID your network's "name" and the password in the indicated places. Some text editors, including Apple's TextEdit included with macOS and WordPad included with Windows make changes to the files you edit which render them unusable by the Pi's Raspian operating system.

I've heard that Windows NotePad can also cause problems, but have not personally verified that. There are several good, free options out there you can download with will avoid these problems. For the Mac, I use BBEdit after 30 days, the freely downloaded version reverts to a limited demonstration version, but that limited version still does everything you need it to to edit files on your Pi.

Note that if the file has already been edited with an inappropriate text editor, your best bet is starting over with a clean, unedited copy of that file. Simply editing it again with the correct editor is unlikely to fix the damage. If you really want to use Apple's TextEdit on your Mac, it can be fixed by making a few changes to it's default preferences.

Under Format, choose "Plain Text". Close the preferences pane, then quit TextEdit and relauch. It will now work without messing up your Pi's files. If you have already edited a file before making these changes, you may need to start with a clean copy of the file to get it to work. A telltale sign that TextEdit has screwed up your file: the quotation marks around the SSID and password will show up as "curly" quotes rather than the desired "straight" quotes.

This is a common cause of a wide range of intermittent and hard to diagnose issues, and especially causes problems with the extra load put on the Pi by running WiFi, BlueTooth, a camera, etc.

A minimum of 2 amps. A charger is not the same as a power supply. Chargers are generally not required to provide tightly regulated voltage or may not be able to provide the peak current that the Pi requires. That old phone charger probably won't work, or if it does, it may cause you intermittent problems.

Get an appropriately rated power supply from a reputable source. Likewise, plugging your Pi into the USB port of your laptop computer is not likely to work reliably. Those ports are usually limited in their current output. If you're lucky, the bare Pi might boot with nothing else attached to it, but WiFi will likely not work, nor things you attach to the Pi's USB port. On a related note: you need a good quality cable to connect your power supply to the Pi.

Many USB cables have conductors that are too small to carry 2. A sub-par cable can show the same symptoms as a weak power supply. Try moving your Pi closer to the router as a test even if that is not possible to do when you are printing, the test will at least let you know if this is the issue. If this solves your connection issue, try relocating your Pi or your router. Sometimes even a small move can make a big difference.

Minimize the number of walls or other obstacles blocking the signal, move things out from behind metal boxes or other electrical devices.

My router sat behind a metal electrical service box in my basement. It worked Ok for other devices in my home, but not the Pi. Building a shelf that positioned it just a couple of feet away made a significant difference in signal strength and WiFi reliability for my Pi.

Please refer to the corresponding Heads-up boxes in the basic setup guide above and adjust the network configuration file octopi-wpa-supplicant. Electrical interference from some appliances can cause interference with the Pi's WiFi reception. Items such as florescent lights, dimmer switches, some LED lights typically, it's the power supplies in V LED lights, not the lights themselves , some electric motors, etc.

Electrically "noisy" devices often create radio frequency interference, which can wreak havoc with the Pi's WiFi signal. This can cause intermittent problems which are hard to diagnose as those appliances turn on and off. This is an issue with similar symptoms to using the wrong text editor. Cutting and pasting commands or text from some sources can cause problems. Install the image to your SD card , then plug everything in to your Raspberry Pi and boot it up.

Do not format the SD card after installing, even if prompted to do so. This will break the installation and you will have to start over! Log into your Pi via SSH it is located at octopi. Run sudo raspi-config. Once that is open:.

You can navigate in the menus using the arrow keys and Enter. All log files that OctoPrint writes can be found in the logs sub folder in its configuration directory:. Additional OctoPrint Source.
