Installation
Flash Layout
 Please check out the article flash.layout. It contains an example and a couple of explanations. |
OEM easy installation
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://192.168.10.1 - Login using user and password printed on stock label
- Select Tools→Firmware
- Browse to
openwrt-ar71xx-generic-tew-732br-squashfs-factory.binfile - Press Upgrade button to upload file to router
- Wait for it to reboot
- Telnet to 192.168.1.1 and set a root password, or browse to
http://192.168.1.1to use LuCI.
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://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://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot

Set up your Internet connection, configure wireless
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)
| Update with actual VLAN info |
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 |
