The general method for picking the right image is visiting the Table of Hardware, then matching the "Platform & Frequency" of your device with the image you're downloading. Sometimes, the "Status" column will have additional information for your device, such as building its image or device-specific installation instructions.

If there isn't a pre-built image for your device, follow the Building OpenWrt instructions to build a custom image.

Any bugs in the firmware should be reported via the ticket system.

Bleeding Edge

The trunk, currently named "Barrier Breaker", is where the current coding happens. It supports more hardware but sometimes doesn't compile. It can be built from sources:

Or some limited snapshots are available, though it's highly advisable that you check the dates on the files before downloading them:


At any time, there are two version of OpenWrt available for download: the latest stable version or the latest nightly build known as the bleeding edge version (Barrier Breaker). There are advantages and disadvantages to each choice.

First, there is the usual difference that the nightly build contains all latest updates and fixes, and allows you to use all OpenWrt features currently supported on your router. However, this also means you could hit a bug which was only recently introduced and has not been fixed yet. The release is tested more thoroughly, and is usually safer. Generally, if you wish to play it safe, install the release; if you wish to experiment and write custom scripts, install the nightly build.

Secondly, there is a small difference you might notice between these versions: As the release is more polished, you will have the Luci web interface installed by default, whereas with the bleeding edge version you need to install it via SSH yourself. This confirms once again the nightly is tailored for the adventurous type, where as the release is safer and easier.

Once you have decided which version you are going to install, grab the image from the download server.

For the release, go to: (substitute 10.03.1 with the latest version of the backfire release, if necessary substitute backfire as well with the name of the latest release).

Next, decide if you wish the squashfs or jffs2 version. The difference being the squashfs version uses a read-only file system with a read-write overlay; and the jffs2 version uses a read-write file system. In the end, you can make modifications to both versions, but you are either making it straight on the file system or on the transparent overlay. The overlay version (squashfs) is slightly safer, where as the jffs2 version is more powerful. For normal usage, squashfs is more than enough.

Finally, decide which version you need:

  • If you are going to install via the normal OEM firmware upload, grab the file with "factory" in the name, e.g. openwrt-ar71xx-generic-wrt400n-jffs2-factory.bin
  • If you already have OpenWRT and you wish to upgrade while keeping your settings, use the file with "sysupgrade" in the name, e.g. openwrt-ar71xx-generic-wrt400n-jffs2-sysupgrade.bin
