Keep the articles modular

Please include only model specific information, omit bla,bla and put everything generic into separate articles
generic.overview if you have no time to write certain stuff link to this
basic.config should lead the way, do not explain this again
DO NOT provide a complete howto here! Instead groom the general HowTos.

Installation

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

If you want to upgrade using TFTP you follow these steps (as an alternative to the above install process.

Upgrading OpenWrt

generic.sysupgrade

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 192.168.1.1
  • Use the following commands to upgrade.

cd /tmp/
wget 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://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Basic configuration

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

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)

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

The Linksys WRT54GL has two buttons. They are Reset and Secure Easy Setup. Here, we merely name the buttons, so we can use them in the above Howto:

Bootloader Mods

  1. you could read about bootloader in general

Hardware mods

  1. as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!
