Firmware for Freifunk Bodensee

The firmware turns a common wireless router into a mesh networking device. It connects to similar routers in the area and builds a Wifi-mesh network but also opens an access point for computers to connect over Wifi. Included is Internet connectivity and a web interface.

Please talk to us on IRC if anything does not work!

Precompiled firmware images are available on our server. You can search them via Firmware-Wizard. All other released versions here on github are out-of-date.

To build the firmware yourself you need a Unix console to enter commands into. Please have a look at the different Branches if you want to build the newest Beta-Firmware Version.

Install dependencies for the build environment (Debian/Ubuntu):

    sudo apt-get update; sudo apt-get upgrade
    sudo apt-get install subversion g++ zlib1g-dev build-essential git python
    sudo apt-get install libncurses5-dev gawk gettext unzip file libssl-dev wget

Build commands for the console:

    git clone git://git.lede-project.org/source.git
    cd source
    git reset --hard 01d7a5d7dee247c40a7ecfbd7ba221640752e76f 
    ./scripts/feeds update -a
    ./scripts/feeds install -a
    git clone https://github.com/ffbsee/firmware.git -b master
    cp -rf firmware/files firmware/package .
    git am --whitespace=nowarn firmware/patches/lede/*.patch
    cd feeds/routing && git am --whitespace=nowarn ../../firmware/patches/routing/*.patch && cd -
    rm -rf firmware tmp
    make defconfig
    make menuconfig

Now select the right “Target System” and “Target Profile” for your AP model:

For example, for the TL-WR841ND v3, select:

  • Target System => Atheros AR7xxx/AR9xxx
  • Target Profile => <*> TP-LINK TL-WR842N/ND v3

Or in case you have the Ubiquiti UniFi Outdoor, select:

  • Target System => Atheros AR7xxx/AR9xxx
  • Target Profile => <*> Ubiquiti UniFi Outdoor

For other models you can lookup the “Target System” in the OpenWrt hardware table. Your AP model should now be visible in the “Target Profile” list.

Please notice, that some Routers need different drivers for 5GHz. Sometimes you need to select them manually.

Now start the build process. This takes some time:


You have the opportunity to compile the firmware at more CPU threats to speed up the process. e.g. to run 3 jobs (commands) simultaneously use the following option:

make -j 3

The firmware image files will be stored in the bin-folder. These images can now directly be used to update your router. Please note, that two differnt image types (per router) will be provided:

  • Use openwrt-[chip]-[model]-squashfs-factory.bin for the initial flash (for routers running stock/vendor firmware).
  • Use openwrt-[chip]-[model]-squashfs-sysupgrade.bin for futher updates (for routers having already another Freifunk FW flashed).

Many routers have not been tested yet, but may work. Give it a try! :-) …and tell us about your experiences
