ASUS RT-AC1200

Under Construction!
This page is currently under construction. You can edit the article to help completing it.

This is a dual band 802.11ac AC1200 fast ethernet wireless router. There are four non-detachable antennas and a USB2 port.

FIXME Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it.

RT-AC1200 v1

FIXME

Getting started with a new Device Page

  1. This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that you have to fill it with life and information.
  2. There are several “fixme” tags with text on a light background (like this text) throughout this template. As you fill in the page, remove those tags so that people can judge its completeness.
  3. When there are no more “fixme” tags left, delete this one too, along with the <WRAP> that encloses it.

Keep the articles modular

  • Please include only model specific information, omit bla,bla and put everything generic into separate articles
  • If you have no time to write certain stuff, link to docs
  • base-system should lead the way, do not explain this again
  • DO NOT provide a complete howto here! Instead groom the general documentation.

FIXME Please add the installation procedure here.

Flash Layout

FIXME Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

OEM installation using Asus Recovery firmware tool

  1. Download the Asus recovery firmware (windows) tool from http://dlcdnet.asus.com/pub/ASUS/LiveUpdate/Release/Wireless/Rescue.zip
  2. Set your ethernet IP manually 192.168.1.5 / 255.255.255.0 with NO gateway.
  3. Plug in your ethernet to LAN port 1 on the router.
  4. Load up the recovery software with the squashfs-sysupgrade.bin firmware file, but don't press “Upload” yet.
  5. Plug in the router to power WHILE HOLDING the reset button in. While CONTINUING to hold the button, select “Upload”. Continue to hold the Reset button in until it finishes and verifies!
  6. If that doesn't work try pressing “Upload” first just before you do step 5. At some point while holding reset the rescue tool will finally detect and upload the firmware. That's when you can let go of the Reset button.
  7. The router will reboot and not much will happen. Wait a minute or two.
  8. Power off and on the router again. Voila. Set everything your Ethernet IP back to DHCP (automatically) and you're good to go.

OEM installation using the TFTP method

→ generic.flashing.tftp

Specific values needed for tftp

FIXME Enter values for “FILL-IN” below

Bootloader tftp server IPv4 address FILL-IN
Bootloader MAC address (special) FILL-IN
Firmware tftp image Latest OpenWrt release (NOTE: Name must contain “tftp”)
TFTP transfer window FILL-IN seconds
TFTP window start approximately FILL-IN seconds after power on
TFTP client required IP address FILL-IN

Upgrading OpenWrt

→ generic.sysupgrade

FIXME These are generic instructions. Update with your router's specifics.

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

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Debricking

Use the Asus Firmware recovery tool to install the Asus stock firmware image for the RT-AC1200.

Instructions for how to use the Asus firmware recovery tool are described earlier in this wiki page.

Specific Configuration

FIXME Please fill in real values for this device, then remove the EXAMPLEs

Network interfaces

The default network configuration is:

Interface Name Description Default configuration
br-lan EXAMPLE LAN & WiFi EXAMPLE 192.168.1.1/24
vlan0 (eth0.0) EXAMPLE LAN ports (1 to 4) EXAMPLE None
vlan1 (eth0.1) EXAMPLE WAN port EXAMPLE DHCP
wl0 EXAMPLE WiFi EXAMPLE Disabled

Switch Ports (for VLANs)

FIXME Please fill in real values for this device, then remove the EXAMPLEs

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) EXAMPLE 4
LAN 1 EXAMPLE 3
LAN 2 EXAMPLE 2
LAN 3 EXAMPLE 1
LAN 4 EXAMPLE 0
