ASUS RT-AX57M

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

ASUS RT-AX57M, RT-AX54HP V2, RT-AX1800HP V2, RT-AX1800S V2, and RT-AX3000S all use the same firmware and have identical hardware (as per commit)

Generic Router

FIXME

  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.
  • 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

  1. The tables below are automatically generated, once the correct filters for Brand and Model are set.
  2. If the tables below show information for ASUS RT-AX57M , everything is OK and you can delete this text and the <WRAP> that encloses it.
  3. If the tables below contain “Nothing found”, it means that either
    1. the dataentry page for ASUS RT-AX57M is missing. Please create a new dataentry page first, then reload this page. The tables should then contain $something. If they do, delete this text and the <WRAP> that encloses it.
    2. filters are not set correctly. Most common reason for “Nothing found”: The dataentry does not contain a Version, but we are filtering here for version → Please edit this section and adjust the filters with the proper Brand, Model and Version. In case the dataentry does not contain a version, delete the line filter : Versions~. Just try, it's easy. The tables should then contain $something. If they do, delete this text and the <WRAP> that encloses it.
  4. If the tables still contain “Nothing found”: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.

None at this time.

Install OpenWrt (generic explanation)

?p=openwrt/openwrt.git;a=commit;h=fafb36f865ce7406085f970adad36ff85ea860d9

As per commit above:

Installation
-----------------------------------------------------------
Vendor-UI Method
-----------------------------------------------------------
1. Download the OpenWrt initramfs.trx image.

2. Connect the PC via LAN to one of the yellow router ports and wait
   until your PC to get a DHCP lease.

3. Browse to http://192.168.1.1 (or whatever your router IP is configured as)

4. If your router is brand new, finish the setup process and log into
   the Web-UI.

5. Navigate to Administration -> Firmware Upgrade and upload the
   downloaded OpenWrt initramfs.trx image.

6. Wait for OpenWrt to boot. Open the default OpenWrt IP in a web browser and perform a system upgrade using the sysupgrade image as instructed in the top banner.

---------------------------------------------------------------------------
Revert to stock firmware:
1: Install package facinstall -> https://forum.openwrt.org/t/facinstall-package-for-easy-installation-factory-images/177587
2. Install Asus stock trx image via OpenWRT LuCI interface.

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

generic.sysupgrade

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

  • 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

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

Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration (as best can be told) is:

Interface Name Description Default configuration
br-lan LAN & WiFi 192.168.1.1/24
eth0 2.5Gbit port marked WAN (NOTE ISSUE) Setup for DHCP (external), not working
lan1-4 Default LAN 1Gbit port DHCP (internal)
phy0-ap0 Default 2.4GHz Wifi ax/b/g/n DHCP (internal)
phy1-ap0 Default 5GHz Wifi ac/ax/n DHCP (internal)

NOTE ISSUE: On some versions of OpenWRT the wan port has NOT been supported, so the workaround is to move the wan port to the lan and one of the lan ports (in my case lan4) to the WAN.

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

  1. This table is automatically generated, once the correct filters for Brand and Model are set.
  2. If you see “Nothing.” instead of a table, please edit this section and adjust the filters with the proper Brand and Model. Just try, it's easy.
  3. If you still don't see a table here, or a table filled with '¿': Is there already a Techdata page available for ASUS RT-AX57M ? If not: Create one.
  4. If you see a table with the desired device data, everything is OK and you can delete this text and the <WRAP> that encloses it.
  5. If it still doesn't work: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.
