 If you want to know what version you have after installing OpenWrt you can run <code>dmesg | grep m25p80</code> and then take a look in the hardware table (ver1 has 8 MiB , ver2 has 16 MiB).

 === Antenna Mod ===
-Need 4 U.FL connector, 4 cable UFL-F/RPSMA-F 13 centimeters long, 4 Antenna Level One (OAN-0501).
+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.
