Hardware Highlights
Keep the articles modular
| Please include only model specific information, omit bla,bla and put everything generic into separate articles |
| docs if you have no time to write certain stuff link to this |
| checks_and_troubleshooting should lead the way, do not explain this again |
| DO NOT provide a complete howto here! Instead groom the general HowTos. |
Installation
Flash Layout
Please check out the article flash.layout. It contains an example and a couple of explanations.

OEM easy installation
 The instructions below are for Broadcom devices and only serve as an example. Don't leave them in place if they do not apply to a particular device! |
This section deals with how you install OpenWrt from a device freshly opened. Plus the steps required such as reset to factory defaults if the device has already been configured
Note: Reset router to factory defaults if it has been previously configured.
- Browse to http://192.168.1.1/Upgrade.asp
- Upload .trx file to router
- Wait for it to reboot
- Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.
OEM installation using the TFTP method
Specific values you need
| Bootloader tftp server IPv4 address | 192.168.1.1 |
| Bootloader MAC address (special) | FILL-IN |
| Firmware tftp image | Latest OpenWrt release |
| TFTP Transfer Window | 120 seconds |
| TFTP Window Start | approximately 5 seconds after power on |
| TFTP Client Required IP Address | 192.168.1.0/24 |
Upgrading OpenWrt
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
LuCI Web Upgrade Process
- Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
- Upload image file for sysupgrade to LuCI
- Wait for reboot
Terminal Upgrade Process
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
Reverting back to OEM firmware
- get OEM firmware from https://www.asus.com/Networking/RTN12_D1/HelpDesk_Download/
- get ASUS Firmware Restoration tool from https://www.asus.com/Networking/RTN12_D1/HelpDesk_Download/
- follow ASUS Firmware Restoration instructions: (use lan1 port, switch off, hold reset button, switch on still holding reset button, wait for system LED to slow blink (cca 20sec), release reset button, flash firmware via ASUS Firmware Restoration tool
Basic configuration
→ To connect to the newly flashed router it is required that the LAN cable be in LAN Port label “1”
This is the Yellow port closest to the Blue WAN port, no other LAN ports were able to see 192.168.1.1.
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
Specific Configuration
Interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| br-lan | LAN & WiFi | 192.168.1.1/24 |
| vlan0 (eth0.0) | LAN ports (1 to 4) | None |
| vlan1 (eth0.1) | WAN port | DHCP |
| wl0 | WiFi | Disabled |
Switch Ports (for VLANs)
Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.
| Port | Switch port |
|---|---|
| Internet (WAN) | 4 |
| LAN 1 | 3 |
| LAN 2 | 2 |
| LAN 3 | 1 |
| LAN 4 | 0 |

Opening the case
Note: This will void your warranty!
- To open the cover remove four screw under the rubber pads
- There are also two plastic latches: one in the middle of the front and one on the back
Main PCB
Serial
→ port.serial general information about the serial port, serial port cable, etc.
The values in this section needs to be confirmed
Serial console should be the header mount point labelled J4 (connector lacks, it has to be soldered on the board).
How to connect to the Serial Port of this specific device:
The pins assignment should be:
| Pin | Signal |
|---|---|
| 1 | RxD |
| 2 | TxD |
| 3 | GND |
| 4 | VCC |
The settings are: 16550 115200 bauds, bits, parity, stop bit
JTAG
→ port.jtag general information about the JTAG port, JTAG cable, etc.
