Hardware

Supported RT-N12 models (and FCC ID):

RT-N12 [A1] (MSQ-RTN12) Broadcom BCM4716
RT-N12B1 (MSQ-RTN12B) Broadcom BCM5357
RT-N12C1 (MSQ-RTN12C) Broadcom BCM5357
CPU Speed 300 MHz
RAM 32 MB
Flash ROM 4 MB (A1), 8MB (B1, C1)
Wireless b/g/n
MIMO 2x2:2

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.

Recovery Mode

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.

Clear NVRAM

To clear NVRAM on all models, hold the red WPS button for 20 seconds when applying power. Do NOT 30/30/30.

A1, B1, C1 Installation

Minimum supported builds are in Supported_Devices.

RT-N12 [A1] Firmware

dd-wrt.v24-14929_NEWD-2_K2.6_mini_RT-N12.trx

RT-N12B1 Firmware

dd-wrt.v24-17990_NEWD-2_K2.6_mini_RT-N12B1.trx

RT-N12C1 Firmware

dd-wrt.v24-18774_NEWD-2_K2.6_mini_RT-N12C1.trx

Installation Procedure

WARNING: This is only for the original RT-N12 [A1], B1, and C1 revisions. Read the Peacock announcement.

  • If you have issues, try a different browser, restart it, or clear your cache
  1. Download the appropriate firmware for your hardware revision
  2. Connect only the PC with an ethernet cable to a router LAN port.
    • Disable all other network and wireless adapters, and disconnect other cables
  3. Set the PC to a static IP in the same subnet as the router, e.g. 192.168.1.10, subnet mask 255.255.255.0
  4. Unplug the power connector from the back of the router.
  5. Put the router into Recovery Mode.
  6. Use the Asus Firmware Restoration Utility (or any TFTP client) to upload the DD-WRT mini-asus.trx file
  • DO NOT DISTURB THE ROUTER or PC FOR THE NEXT FIVE MINUTES. BE PATIENT!
  1. After the upgrade, the Utility should ask for a router reboot. WAIT another minute then unplug the power.
  2. Plug back in after 10sec, then after boot, access DD-WRT at 192.168.1.1, set a password and configure
  3. Set the network adapter properties for TCP/IP back automatic DHCP (IP/DNS)

Alternate Installation Procedure

If the above procedure does not work, try this:

  1. Connect only an ethernet cables from the RT-N12 to your PC network adapter, and disable wireless.
  2. Ensure DHCP is enabled in the ASUS firmware for automatic IP/DNS
    • Open a browser, it will instruct to plug in the WAN (internet) cable. If not, reboot the router and/or PC.
  3. Put the router into Recovery Mode.
  4. Open the router GUI at 192.168.1.1. The page will open to CFE HTTP recovery console.
  5. Click on the link below Reboot to reset the NVRAM.
  6. Click the Browse button to browse to your DD-WRT firmware file location.
  7. Click the Upload button.
    • The router will upload and open a screen that says "Allow router time to reboot." WAIT another 5 minutes. You will see the LAN1 light turn off and notice the "Network Cable Unplugged" windows popup message in task bar. Wait for the light to turn back on and the PC to reconnect to router.
  8. Click "Continue" on that page to reboot again, then the DD-WRT admin login screen should open.
    • If the login screen is white and looks very basic, reboot the router again by removing the power cable.

RT-N12D1 Installation (updated March 21 2018)

The D1 revision has the same specs as B1 and C1, and can run DD-WRT firmware (reports as Asus RT-N12B1).
However, installation requires some special steps. These instructions are based on [1]

The tools you are going to need are listed below:

  • The Asus “Firmware Restoration” program
  • Asus Firmware: Version 3.0.0.4.374.813
  • dd-wrt.v24-14896_NEWD-2_K2.6_mini_RT-N12.trx
  • dd-wrt.v24-18774_NEWD-2_K2.6_mini.bin
  • dd-wrt.v24-33215_NEWD-2_K3.x_mega.bin

The first 4 can be found in a ZIP file at www.craigonsite.com/s/Asus_RT-N12D1_DD-WRT.zip

Once you have the files downloaded you should be ready to go through these instructions for loading DD-WRT on the Asus RT-N12 D1. It seems stupid to do it the way listed below BUT it’s the only way the firmware can successfully and consistently loaded.

These steps below are for installing DD-WRT on a brand new Asus Rt-N12 D1 with the stock Asus firmware already on there. (If you have bricked your router refer to the Unbricking Your Asus Rt-N12 D1 section in the reference

  1. Setup your computer’s NIC to a static address. I suggest using 192.168.1.2

    When prompted enter the username and password. The default for both is “admin”.
    This will bring you into the Asus stock firmware where we can upload a TRX file for DD-WRT.
  4. On this page Browse to the firmware you downloaded: dd-wrt.v24-14896_NEWD-2_K2.6_mini_RT-N12.trx then click on Upload.
  5. After clicking Upload you’ll have to wait for the firmware to upload. The router will reboot a few times. That’s fine. Just wait, you’ll see the progress bar move. The router will go into a reboot cycle where it reboots over and over. Believe it or not, that’s actually a good thing.

  15. Using the DD-WRT web interface update to firmware dd-wrt.v24-33215_NEWD-2_K3.x_mega.bin

RT-N12HP and RT-N12VP

These have the same specs as the B1, C1, and D1 hardware. One user successfully flashed a RT-N12HP B1 with dd-wrt.v24-18774_NEWD-2_K2.6_mini_RT-N12B1.trx, but the others are unknown. Proceed at your own risk!

Asus RT-N12+ and RT-N12E B1

Not supported, but Padavan third-party firmware can be used. Reference threads: [2], [3]
