No WIFI device on Raspberry PI 4

Hello, I have this problem, when I start REPETIER I no longer have any wifi connection in the WLAN settings I get this message: NO WLAN ADAPTER INSTALLED (the configuration is Repetier Server Pro 1.3.0 on Raspberri PI 4).
Kindly how can I solve Thanks

  • This actually just means that iwconfig does not report a wifi device for wlan0. It sounds like it worked before so first try would be reboot and next is the question what you did between where it worked and when it stopped working?

    When you login (use ethernet cable as long as it does not work), what does
    iwconfig
    return?

    Also after reboot run
    dmesg
    to see messages during bootup. Maybe they contain a hint on the problem.

    If you have a extra sd card, install image on new sd card and see if it happens there as well. If not copy your server installation (e.g.  Repetier-Server Monitor) to new card. Maybe just some defects on sd card made it break. Especially if you did nothing like update/config/install extra software.
  • Hi, in the attachment I am sending you an answer to the commands you indicated. Kindly tell me how can I restore the WIFI.Thank's


  • You can not attach files here. Please just copy the text into forum. Should be not too many lines.

    What about the question what you did between working and not working version?
  • I apologize for the publication of the data, I reply that nothing has been done between working and not working version, I inform you that by deleting the repetier server in WLAN and recreating the Repetier server with lan cable the connection works, I still hope you can solve the problem connection in WLAN Thank you
  • Good it works with cable. That way you can easily try the server backup/new sd card solution in case a sd file defect is causing this. Without the logs it is not possible to say more. And even with it might take several iterations of information exchange to find what got corrupt, that is why new sd card and copy all data is normally much faster.
