Flashing DD-WRT
Supported, Wiki Flashing from Stock Asus FW to DD-WRT This procedure places the router in recovery mode, then uses AFRU to upload the DD-WRT (official or third-party) .trx file. Subsequent updates, if any, are much easier (see Updating DD-WRT)

1. Preparation for Initial DD-WRT Install
 * 1. Download desired DD-WRT FW file
 * Read the above and select file desired. Be absolutely sure it is right one, v1 vs B1.
 * Be sure file is '.trx' (.bin files are for updates only, for use only after DD-WRT is installed).


 * 2. Download latest version of the Asus Firmware Restoration Utility
 * From a Windows machine, Browse to http://support.asus.com/download
 * Navigate to device model number, -N13U or -N13U-B1
 * Select OS
 * Click '+' next to 'Utilities', select version and download
 * Within the zip file, navigate to the */Utility folder and run 'setup' to install AFRU.
 * Be sure AFRU can be started with no problems


 * 3. Download safety copy of Asus firmware (optional)
 * Do same as previous step, except click '+' next to 'Firmware' and download desired version.
 * Note that this file should not be needed; use only to restore Asus FW to router if later desired.


 * 4. Last few checks
 * If not already directly wired, connect Ethernet cable from one of the router's LAN ports to client PC.
 * Be sure router's other three LAN ports and WAN port are open (nothing connected)
 * On PC, disable all other network adapters: wireless, modem, etc.
 * On PC, disable any firewall (Ex. Windows Firewall)
 * Optional: Set PC to use a static IP, Ex. 192.168.1.2, netmask 255.255.255.0, gateway 192.168.1.1
 * If possible, use uninterruptible power supply (UPS) for both PC and router. A power failure while flashing, though not likely, will probably brick the router.
 * Last check: Flashing a v1 FW to a B1 device will brick it, and vica versa. Be sure the FW file that is about to be flashed is the correct one for the device.

2. Flash to DD-WRT
 * 1. Place router in Recovery mode
 * Disconnect power adapter plug from router
 * Push and hold the Restore button located on bottom panel. While continuing to hold down the Restore button, plug the power adapter back into router.
 * After five seconds, LED on front panel starts to blink, release the button.


 * 2. Upload firmware image
 * On PC, open AFRU (installed earlier)
 * In Firmware Restoration window, click 'Browse' and select the DD-WRT image file, asus-to-ddwrt.trx (downloaded earlier)
 * Click 'Upload' to begin flash process that can take up to four minutes. Brick warning: Do not interrupt!
 * When message that router is rebooting appears, close AFRU window.

3. Reboot, launch DD-WRT web interface, and cleanup
 * After a minute or two, disconnect power adapter plug and leave for at least 10 seconds
 * If optional step of setting static IP was followed earlier, can now reset to automatic
 * Connect WAN port then reconnect power plug
 * Browse to 192.168.1.1 should bring up the DD-WRT web interface; set name/password for first access
 * Configure router as desired. Default connection is DHCP; for DSL check DSL with DD-WRT..
 * When satisfied that factory firmware will not be used again, uninstall Asus Utility from PC and delete Asus files.

Upgrading
Updating DD-WRT This task is straightforward enough that it needs nearly no instruction.
 * 1) Backup any scripts, files or settings that are intended for reuse.
 * 2) Select and download the correct DD-WRT binary file, .bin, from the repository (see Firmware Repository, above)
 * 3) In the DD-WRT web interface, navigate to Administration | Firmware Upgrade tab, click 'Browse', select the downloaded .bin file, and click 'Restore'.
 * 4) After restart, restore any backups as desired.
