Onion Omega seems to have no wifi

  • Hi,

    My Onion Omega seems to have no wifi.
    When connected, there is no blinking LED , and no Omega-XXX network appears.
    If it is really dark, I can see the LED glowing very very faintly.

    I can see the Omega boots to a login prompt when I connect a USB cable.
    When I login as root however, there is only eth0, eth1 and lo.
    The suggested command to set up wifi is not available.
    Running rc file for the wireless network results in a syntax error.
    Running the AP setup scripts results in a reboot.
    If I load the modules from the rc file by hand, a wifi0 interface appears, but
    iwconfig says 'no wireless extensions' for all interfaces.

    Do you have any hints? To me this looks like a wrong firmware, like https://community.onion.io/topic/63/password

    Or could the mini-dock be at fault?
    The switch of the mini dock snapped at first use, but I managed to switch it with a needle, and as stated above, the Omega does boot all the way to the login prompt.
    Can I maybe connect another powersource directly to the Omega? I have a breadboard with 3.3V and 5V power options, I just don't know which pins to use.

  • @N-Willems I'm really sorry, but your Omega is flashed with the testing firmware during manufacturing. Can you confirm that your address is the same as the one we've sent the Omega to? We will send you a free Ethernet Dock and show you how to flash the Omega to the correct firmware.

    I'm really sorry about the confusion!

  • @Boken-Lin
    No worries, I assume you guys are under a lot of pressure at the moment, so I very much appreciate all your efforts. Accidents happen.

    I can confirm my address has not changed.
    Please note I only have the mini dock, and I'm not sure Ethernet dock will fit.

  • @Boken-Lin Any news on this? Haven't heard from you guys since my confirmation.

  • Hi @N-Willems, We sent out a package to you around two weeks ago. You should be receiving it in a week or so.


  • @Boken-Lin Thanks man!

  • @Boken-Lin
    I received the ethernet expansion and matching dock today šŸ™‚

  • @N-Willems Ok, now you will need to re-flash the Omega with the new firmwares. Please take a look at the wik article here: https://wiki.onion.io/Tutorials/Reflash-The-Firmware-With-Ethernet-Expansion. Can you following the steps until Step 6. Then take a screenshot of your browser window? The re-flash process will be slightly different because you will be flashing on a new uboot first. Once you put up a screenshot here we will walk you over the flashing procedures.


  • @Boken-Lin , I tried, but I can only get to step 4, no httpd.
    However, I configured my laptop's networkinterface, and I can ping just fine over the ethernet. And I see a tftpboot command. If I'm not mistaken I only need the correct arguments for it.

    Here the output:

  • Hi @N-Willems, My mistake. You will first need to use tftp to flash the uboot to the production one first. You can do it by serving a tftp server on your computer, and running the following commands in the current uboot:

    setenv ipaddr   
    setenv serverip
    tftp 0x80000000 uboot.bin
    erase 0x9f000000 +0x10000
    cp.b 0x80000000 0x9f000000 0x10000

    The uboot binary can be downloaded from: https://s3-us-west-2.amazonaws.com/onion-downloads/openwrt/uboot_for_omega_final.bin. Please make sure that you first disconnect from your Wifi network on your computer, so that the IP address for your computer is assigned properly.

    After, you are done with that, you will need to flash the ART partition (which contains Omega WiFi calibration data). You do this by going into the FIrmware re-flash interface, as outlined by the wiki article https://wiki.onion.io/Tutorials/Reflash-The-Firmware-With-Ethernet-Expansion. But, instead of flashing the firmware image, you will click on the link at the bottom of the screen which says ART Update. ART partition binary can be downloaded here: https://s3-us-west-2.amazonaws.com/onion-downloads/openwrt/art_for_omega.bin.

    Then, you will need to tell the Omega what it's MAC address is. Reboot again, and enter the uboot prompt, and issue the following command:

    setmac 40:A3:6B:C1:06:C5

    Finally, you will be flashing the firmware for the Omega, which can be downloaded here: http://repo.onion.io/omega/images/.

  • @Boken-Lin We made it! šŸ˜ƒ

  • @N-Willems Yay!! That's awesome šŸ™‚

  • Thanks for your assistance, great support! šŸ‘
