What is the problem
my pi 4b is not connecting wireless
What did you already try to solve it?
ssh into the pi when connected to ethernet and changing setting
Have you tried running in safe mode?
N/A
Did running in safe mode solve the problem?
N/A
It would be much easier for us to help if you provided details of your journey to failure...
What version of the OS are you using? Is it a fresh install? What imager did you use? Did you initially configure WiFi with the imager?
After connecting with ethernet and SSH, how did you change the settings?
my fault, i am using octopi 1.10.03 (stable) i used the raspberry pi imager, i configured the wifi with imager and wpa.txt, i changed the setting via ssh= the region wifi name and password.
i have the wifi intergrated model but when i pull the ethernet cable out it just does not connect i checked and the raspberry can see the wifi network and the network has a pretty good quality.
i first got an pi 2b just connected to ethernet i switched today to an pi 4b with 4GB i got the right image but it still wont connect to the wifi
There is no "octopi 1.10.03" (but there is OctoPrint 1.10.3).
What version of the Raspberry Pi Imager? What image did you use? How did you answer "Use OS customization?"
If the answer is "Edit Settings", what settings did you select?
Since you can use ethernet to SSH into the RPi, please provide the output of:
ifconfigiwconfigiwlist wlan0 scan | grep -e ESSID

How did you come to this conclusion (i.e. what commands on the RPi did you use and what was the output)?
yes i meant octoprint

used this for the testing of the wireless network quality sudo iwlist wlan0 scan | less
raspberrypi imager vers. 1.9.0
sudo raspi-configSystem OptionsWireless LAN- Enter one of the ESSIDs from the list you posted
- Enter the passphrase for this ESSID
- Finish (use TAB to get there)
iwconfig
saying there was an error option S1 wireless LAN
reasons? maybe running a print
What image did you use to install the OS on the Raspberry Pi?
If sudo raspi-config errors out when attempting to select the Wireless LAN option, then my conclusion is that the OS image you are using is corrupt (or previous attempts to configure wireless has corrupted something).
I have installed OctoPi / OctoPrint many times and configuring the Wireless connection using "Edit Settings" in the Raspberry Pi Imager has never failed as long as the SSID, passphrase, and Wireless LAN country have been set correctly.
so just let the imager rewrite?
let me check the image.
i cant find the image but do i just need to cancel my print and let it rewrite?
i plugged in the microsd card and found that the wpa setup file was missing
You can finish your print.
If you have a spare microSD card of sufficient size, then you can download and flash a new image while your print is running. Then swap cards and reboot the RPi when the print is done.
alright i got a backup for the print im gonna put it back and start thanks for your help,
mister B.
one question when you have configured wireless lan and do the iwconfig what do i need to see?

it is still not working i got no error code no nothing how long do i need to wait after pulling out the ethernet? or just a whole reboot?
When I switch SSIDs, it takes less than a minute to reconnect.
I would start over from scratch.
In the RPi Imager, I would select Raspberry Pi 4, Other specific-purpose OS, 3D Printing, OctoPi, OctoPi (stable) and write a new image onto a microSD card. I use 32GB cards but anything bigger than 8GB should be fine.
In the imager, I would Edit Settings, set the hostname, set the username to "pi", set the password, configure the Wireless LAN, set the locale, click Services at the top, enable SSH and Use password authentication.
On my RPi 4B, I would attach an HDMI monitor and a USB keyboard. Insert the microSD card and then plugin the power supply.
i got to go to bed ill do it tommorow thanks (europian times)
i am back and tried again still no succes. is there maybe something else having to do with it?
