ASUS WL-320gE / WL-320gP

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version (18.06 or later) onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device will end after 2019.
19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See OpenWrt on 4/32 devices what you can do now.

The ASUS WL-320g is a simple wireless access point featuring one fast ethernet port and 54Mbps Broadcom wireless. The WL-320gP variant is PoE capable.

Supported Versions

Version/Model S/N OpenWrt Version Supported Model Specific Notes
WL-320gE - 7.06+ 1 antenna

Installation

Installing the firmware is possible using the standard TFTP upload procedure.

See generic.flashing

OEM installation using the TFTP method

  • Hold the reset button
  • Power on the device

As other ASUS models, the bootloader will use the IP configured in the nvram lan_ipaddr and lan_netmask variables when waiting for a TFTP upload.

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 TRX file 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/latest/brcm-2.4/openwrt-brcm-2.4-squashfs.trx
sysupgrade /tmp/openwrt-brcm-2.4-squashfs.trx
  • If sysupgrade does not support this router, use the following commands.
cd /tmp/
wget http://downloads.openwrt.org/latest/brcm-2.4/openwrt-brcm-2.4-squashfs.trx
mtd write /tmp/openwrt-brcm-2.4-squashfs.trx linux && reboot

Asus WL320gE PCB

Serial

J5 is a LVTTL Serail for the SoC's COM0 and COM1 (RX/TX only, no flowcontrol). J3 is an external RJ-12 connector for the COM0 (unsoldered).

1 - RX1 RX0 - 2
3 - TX1 TX0 - 4
5 - GND VCC - 6
7 - RESET   - 8

Pin 1 (with the square solder pad) is RX1. Serial pinouts is similar to the Asus wl500gp.

See port.serial for more info.

GPIO

reset_gpio=7

Other GPIO pins are available on the J6.

See port.gpio article for more info. NOTE! WGT-54G layout is different.

USB

BCM5332 SoC's USB 1.1 ports are connected to the J1. The connector and USB chip-resistors are not soldered.

JTAG

No / Not known. Be very careful at upgrading/reflashing!

Specific Configuration

The WL-320gE and WL-320gP have one LAN port only, however it seems to be connected internally as switch port 3. So your switch configuration should look something like this:

config 'switch' 'eth0' option 'reset' '1' config 'switch_vlan' 'eth0_3' option 'device' 'eth0' option 'vlan' '0' option 'ports' '3 5*'

See network configuration for details.

Interfaces

The default network configuration is:

Interface Name Description Default configuration
br-lan LAN & WiFi 192.168.1.1/24
vlan0 (eth0.0) LAN port (3) None
wl0 WiFi Disabled

Switch Ports (for VLANs)

Only one switch port is exposed.

Port Switch port
LAN 3

Failsafe mode

  • Unplug the power cord.
  • Connect the router's LAN port directly to your PC.
  • Configure your PC with a static IP address between 192.168.1.2 and 192.168.1.254. E. g. 192.168.1.2 (gateway and DNS is not required).
  • Plug the power on and wait for the DMZ LED to light up.
  • While the DMZ LED is on immediately press any button (Reset and Secure Easy Setup will work) a few times .
  • If done right the DMZ LED will quickly flash 3 times every second.
  • You should be able to telnet to the router at 192.168.1.1 now (no username and password)
