Preliminary

I have just ordered one of these routers, and it'll be here any day now - so i'll be loading DD-WRT to it.

So far I am gathering information about this router.

Hardware

The ASUS RT-N66U is a Dual Band N-Router (2.4GHz and 5GHz bands) with lots of RAM (256Mb) and FlashRAM (32Mb), so it is well equipped to run DD-WRT

If you are looking for less expensive routers, that are also well suited to run DD-WRT, you might want to check out the Asus RT-N16 Single Band N-Router (2.4GHz only) but still with lots of RAM (128Mb) and FlashRAM (32Mb). Even cheaper is the Asus RT-N10U Single Band N-Router with 32Mb RAM and 8Mb FlashRAM.

Specifications

  • Dual Band Router - 2.4GHz and 5GHz bands
  • Gigabit LAN and WAN switching
  • 2x USB 2.0 connectors
  • CPU Broadcom 4706 @ 600MHz
  • 256MB RAM
  • 32MB FlashRAM
  • Built-in Micro SDHC socket (for up to 8GB Micro SDHC card)
  • Power supply: DC Output, 19 V, max. 1.58 A current

Installation Instructions

Please note: The RT-N66U does REQUIRE the K26 Firmware builds as Broadcom has not released drivers for the non-K26 builds. (Read more here: Recommended Firmwares).

Note: use build 18946, it fixes the WAN port issue.

Principle steps

  • Clear settings (Clear NVRAM)
  • Install the INITIAL ASUS RT-N66U version of DD-WRT (file name ends in .trx)
  • Clear settings (Clear NVRAM)
  • "Upgrade" to your final version of DD-WRT (filename ends in .bin)
  • Clear settings (Clear NVRAM)

How its done

  • Clear settings (Clear NVRAM)
  • You might be able to upload the .trx file using the stock web GUI
  • Or you can likely set it in "Recover mode" (same as other Asus routers) and then use one of the tftp utilities to serve the firmware to the router. Current tftp utilities are:
  • Asus Recovery utility.
  • see Asus_TFTP_Flash for 7 other tftp tools/mentions for Linux, Windows and Mac
  • Clear settings (Clear NVRAM)

How its done v2

- Set your NIC card to static > IP 192.168.1.12, Subnet 255.255.255.0, Default gateway192.168.1.1

- Put router into recovery mode by holding down the reset button while powering up the router, wait until the power led is blinking slowly, then release the reset button.

- Access the router’s built in recovery mode by issuing 192.168.1.1 in browser field.

- Flash DD-WRT build (e.g.) Asus-RT-N66U_18946_mini build and upload. When completed wait at least 10 minutes.

- Put router into recovery mode by holding down the reset button while powering up the router, wait until the power led is blinking slowly, then release the reset button.

- Flash DD-WRT build (e.g.) Asus-RT-N66U_18946_big build and upload. When completed wait at least 10 minutes

- Put router into recovery mode by holding down the reset button while powering up the router, wait until the power led is blinking slowly, then release the reset button.

- Select Reset NVRAM defaults when it completes (should be quick), in the browser field, type in http://192.168.1.1/do.htm?cmd=nvram+commit. When done press enter. When complete select reboot and wait 5-10 minutes for the router to reboot and start building its layers.

- Now you should be able to access via web gui 192.168.1.1 and it should be DD-WRT.

Upgrade to newer DD-WRT

  • Clear settings (Clear NVRAM)
  • use the DD-WRT web gui: Administration -> Firmware upgrade
  • Clear settings (Clear NVRAM)

Install an internal MicroSD card

Open the case

  • Unscrew the four screws at the buttom
  • Then you want to release the plastic clips that holds the top and buttom parts together.
  • You want to "pry" the bottom case outward. The clips have the male part molded into the bottom, the female part is molded into the top cover.
  • For easier access next time, you can either snip off the "U" clips on the top cover, or round off the square edges on the male part of the clip with a nail file. Eithe solution makes it easier to get the case apart next time.

Install MicroSD card

Make use of the MicroSD card

You could install OTRW (Optware, the Right Way) and add OTRW Take 2
