-  * There are separate images for wndr3700 and wndr3700v2 (due to the firmware having to be tagged a different way).  The wndr3700v2 will reject the version 1 images. The version 2 images are available starting from Backfire 10.03.1-RC5.

 === Where to get firmware? ===
   * You can get generic OpenWRT firmware of the [[about:history#stable.releases|stable branch]] from the [[http://downloads.openwrt.org/|official repository]]. This firmware covers most basic needs of an average user.
   * Alternative is a precompiled image from the [[about:history#bleeding.edge.trunk|trunk (bleeding edge) branch]]: [[http://downloads.openwrt.org/snapshots/trunk/ar71xx/]].
-  * An easy way to get a custom firmware with extended functionality is to use a [[toh:netgear:wndr3700#pre-built.customized.firmware|pre-built customized firmware]] based on whether [[about:history#bleeding.edge.trunk|trunk]] or [[about:history#stable.releases|stable]] branch.

+There are two different images available for the wndr3700 series:
+  * **sysupgrade.bin** images are meant for flashing from an existing Openwrt system, either by using LuCI and the sysupgrade script.
+  * **factory.img** images are otherwise identical, but a short header has been added to the image enabling the original Netgear OEM firmware and the TFTP recovery mode to accept the images.

+The procedure below covers hardware revision 1. Revision 2 only has U.FL connectors for the 5 GHz antennas (PJ2 and PJ4), while the 2.4 GHz connectors are replaced with dummy connectors (presumably a Hirose testing connectors used in production). So for revision 2 the PJ5 and PJ6 connectors will have to bypassed and the coax cable soldered directly to the PCB.

 Personally, I think this is a ridiculous situation, but there seem to be issues with fixing it. You can do the job yourself as follows:
+=== Backfire ===
 You may partially fix this by compiling a custom image with CONFIG_ATH_USER_REGD set in the Ath9k driver. This will, however, take a significant time to compile and result in a restriction to 20dBm max power output across all channels (this is apparently due to a bug according to my reading, but it's not fixed yet as far as I can tell). A much better option that will allow you to use the full legal power output in your country would be to follow the instructions here:

 . If you want to see what settings I put in the regulatory DB (they're as per the article I linked at the beginning) you can get them here: https://rapidshare.com/files/458836748/db.txt . If for some reason you want to use this to set the proper regulatory settings for the USA, you need to use UX as the country code...otherwise all country codes are still correct.
