Omega 2S+: No WiFi Support with OpenWRT 21.02



  • @crispyoz
    I got this:
    root@OpenWrt:/# iw dev apcli0 scan | grep -i ssid
    command failed: No such device (-19)
    Do I miss something?
    I do not need it to connect to a network. I need it to provide one.
    When I did wifi up the radio0 doesn't be up and I cannot see the ssid on my phone.

  • @IBH Strange, everything looks correct to me, but iw status does not show the SSID. After you made changes to the wireless file, try rebootig and wait for a minute before running wifi status. Also try making these changes:

    uci set wireless.radio0.channel='auto'
    uci set wireless.sta.disabled='1'
    uci commit wireless

    Then reboot.



  • @crispyoz I've tried that too but still no luck 😞


  • administrators

    @IBH Maybe try using the 21.02 firmware released by OpenWRT: onion_omega2p-squashfs-sysupgrade.bin at https://downloads.openwrt.org/releases/21.02.5/targets/ramips/mt76x8/

    If the wifi works using that firmware, then it points to an issue with the customized firmware you've built.



  • @IBH I put my firmware binary on my github, you just need to add the wifi configuration I posted earlier. If that works for you I can share my build config. If the Onin version works for you as provided by @Lazar-Demin go with that one as mine is based up on the standard OpenWrt build.



  • @crispyoz Thank you , we are using same as you an Openwrt build and we don't use onion-openwrt . Will check with your firmware binary and @Lazar-Demin's firmware too. In fact, it is strange that we have the wlan interface and everything looks good but we couldn't see the SSID and have the connection.



  • @IBH I wonder if you tried treating the AP WiFi SSID as hidden and connect manually. Your WiFi command shows he SSID is not configured as hidden but it's just a thought. Anyway we know my config works on my build so the answer is there somewhere.

    Looking at the bigger picture, you probably should be using OpenWrt 22 anyway.



  • @crispyoz Do you know how we can verify if the AP WiFi SSID was treating as hidden ?
    For OpenWrt 22, which tag you used for the upgrade from 21 to 22? does it openwrt-22.03 ?



  • @IBH Looking at the output of your "wifi status" command I can see the SSID is not configured to be hidden, I was just pondering if the issue was related to something on your build that caused it to be hidden.

    For OpenWrt 22 I used "openwrt-22.03"



  • Hi @crispyoz, wifi works fine with your build image :MicrosoftTeams-image (17).png
    Could you please tell me if you have rebased the branch openwrt-22.03 into your branch ? Could you please share the steps you have done for upgrading your openwrt build ?

    THank you so much for your time and help.



  • @IBH I don't rebase. Just a git clone, then make menuconfig make kernel_menuconfig add my changes to uci defaults and files directories then make.



  • @crispyoz Do you have a GitHub repo where you've pushed your OpenWrt 22.03 clone with your config changes?
    In fact, If I'm not wrong you git clone the base OpenWrt 22.03 (https://git.openwrt.org/openwrt/openwrt.git)then you've added your feeds and configs right?



  • @IBH My repo is currently private as I am working on something however here as the simple instructions to set up your build system:

    Setup OpenWrt 22.03

    cd
    git clone https://git.openwrt.org/openwrt/openwrt.git openwrt22
    cd openwrt22
    scripts/feeds update -a
    scripts/feeds install -a
    git checkout openwrt-22.03
    make menuconfig
    Target System (MediaTek Ralink MIPS)
    Subtarget (MT76x8 based boards)
    Target Profile (Onion Omega2+)

    Then remove the /etc/config/network and /etc/config/wireless with the settings I gave you earlier in this thread.


  • administrators

    @crispyoz one suggestion:
    do git checkout openwrt-22.03 before scripts/feeds update -a and scripts/feeds install -a

    If you update and install the feeds before changing the branch, you might be using packages meant for the default branch of the openwrt/openwrt repo.
    The feeds.conf.default file points to different branches of the package repositories depending on the branch of openwrt/openwrt.

    See feeds.conf.default in the master branch vs feeds.conf.default in the openwrt-22.03 branch:

  • @Lazar-Demin @crispyoz thanks both. I got this after doings your steps:
    scripts/config/conf: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.33' not found (required by scripts/config/conf) scripts/config/conf: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.34' not found (required by scripts/config/conf)
    /home/ibh/projects/onion-22-03/sources/openwrt-22/include/toplevel.mk:118: recipe for target 'defconfig' failed
    make: *** [defconfig] Error 1
    FYI: I'm using docker for building.


  • administrators

    @IBH Which docker image are you using?

    If it's the onion/omega2-source docker image mentioned in https://github.com/OnionIoT/source#options-for-using-the-build-system, I would recommend against compiling OpenWRT 21 and 22 with this image since it's based on Ubuntu 18.

    I suggest spinning up a new ubuntu 22.04 container and following OpenWRT's build system setup instructions: https://openwrt.org/docs/guide-developer/toolchain/install-buildsystem



  • @IBH use the command ldd --version to determine which verison of glibc you have installed, you may have to install a newer version. Which OS are you building on? Windows/Linux ? As @Lazar-Demin mentioned you can create your own docker container and follow the OpenWrt instructions, personally I install on my Ubuntu system directly without using docker.
