Flash Layout

Please check out the article flash.layout. It contains an example and a couple of explanations.

OEM easy installation

FIXME 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.

OEM installation using the TFTP method

Specific values you need

Bootloader tftp server IPv4 address FILL-IN
Bootloader MAC address (special) FILL-IN
Firmware tftp image (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


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

Terminal Upgrade Process

  • Login as root via SSH on
  • Use the following commands to upgrade.
cd /tmp/
sysupgrade /tmp/
  • If sysupgrade does not support this router, use the following commands.
cd /tmp/
mtd write /tmp/ linux && reboot

Basic configuration

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

Specific Configuration


The default network configuration is:

Interface Name Description Default configuration
br-lan LAN & WiFi
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
