-Special Thanks to Eko+To find the hardware revision, check the device's bottom label or view the top left of the original ASUS firmware. '''Do not flash the initial firmware for a different revision of hardware''' or it may enter an infinite reboot loop. Recovery mode may be possible to fix it.
-Asus RT-N12 is now supported. Actually it is quite good router for its price. <br>+====Recovery Mode====
-If you don't need USB and Giga ethernet and 5GHz, it is good alternative to e.g. Linksys wrt160nv3 etc...<br>+Hold the recessed reset (Restore) button for 20 sec (or until the power LED blinks '''slowly''') and plug in power. Using a static IP for the computer, open 192.168.1.1. The router is now in Recovery or Rescue mode.
-It has bcm4716b0 cpu, 4 MB flash and 32 MB ram + 2 external removable antennas. +
-Please don't flash any old builds.+====Clear NVRAM====
 +To clear NVRAM on all models, hold the red WPS button for 20 seconds when applying power. '''Do NOT 30/30/30.'''

- +
-It appears that as of 30771 (BS) 2016-10-18 D1 is supported [https://www.dd-wrt.com/phpBB2/viewtopic.php?t=305000]+

-Check the label on the bottom of your device or view the Top left of the original ASUS firmware for your hardware revision. Do not flash the initial firmware for a different revision of hardware than yours. You may still be able to recover your device if it enters an infinite reboot loop using recovery mode as a result of loading incompatible firmware. (Hold recover button for 30 seconds when applying the power, with static IP settings on your computer connected via ethernet)+

-To clear NVRAM hold down the WPS button when applying power for 30 seconds on all the RT-N12 models.+
- +
-== INSTALLATION INSTRUCTIONS ==+
- +
- ''' DO NOT use Firefox for upgrading builds! Use Internet Explorer!!!!'''+
- +
-0. Download the firmware above and '''extract''' it to your desktop or a convenient location.+
- +
-1. For simplicity, connect '''only''' the PC to one of the router's LAN ports with a normal [uplink] ethernet cable. No other modem,computers,routers,switches, etc should be connected.+
- +
-2. In order to prevent DHCP from interupting the connection, you will need to manually set the address of your PC's Network LAN card to a '''STATIC IP''' in the same subnet of the router, such as 192.168.1.10 with subnet mask 255.255.255.0 . Also make sure all other adapters,such as wireless, which might be seen as "clients" by the router are disabled. Only the main LAN connection [IP: 192.168.1.10] should be able to communicate with the router.+
- +
-3. Unplug the power connector from the back of the router.+
- +
-4. While pushing & holding the '''recessed''' Restore button on the back of the router, plug the power connector back in. The Restore button is NOT the raised red WPS button.+
- +
-5. When the power LED '''slowly''' blinks on and off, release the Restore button. The router is now in "RESCUE MODE".+
- +
-6. Use the Asus Firmware Restoration Utility [which you should have installed on the PC] to upload the DD-WRT mini-asus.trx file from the location where you saved it.+
- '''DO NOT DISTURB THE ROUTER or PC FOR THE NEXT FEW MINUTES. BE PATIENT!'''+
- +
-6. After the upgrade, the Utility should ask for a router reboot. Give it '''AT LEAST''' a minute to be on the safe side before removing the power. Then unplug the power from the router, wait 10 seconds or so and plug the power back in. You should now be able to access the web interface.+
- +
-7. Return your Net adapter properties for TCP/IP to DHCP "Automatically Obtain IP"+
- +
-8. Type 192.168.1.1 into your browser and set your username as root and pick a password.+
- +
- +
-----+
- +
-== ALTERNATE INSTALLATION METHOD FOR ASUS TO DD-WRT FW UPDATE ==+
- +
- +
-The steps listed above did not work for me, but these steps did.+
- +
-1) Disconnect all ethernet cables from the RT-N12 except 1 going to your NIC. +
- +
-2) Turn off all wireless clients (notebooks, PS3 etc...). +
- +
-2a) Turn off all programs on your computer that may be trying to access the internet - e.g. open browser tabs, IM software, etc.+
- +
-3) Ensure DHCP is enabled in the ASUS firmware and retreive IP/DNS automatically is set in your NIC properties. +
- +
-(When you open your IE browser it will instruct you to plug back in your WAN ISP cable, if your PC is still seeing the router. If not, you may need to reboot router and/or PC.)+
- +
-4) Do the 30/30/30 peacock method of putting your router in recovery mode.+
- +
-5) Open the router IP of 192.168.1.1. The page will open to a built in browser (HTTP) recovery console.+
-6) Click on the link below Reboot to reset/flash the Vram.+====Installation Procedure====
