→ Install OpenWrt (generic explanation)

Please add the installation procedure here.

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

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.

• Browse to http://192.168.1.1/Upgrade.asp
• Upload .bin file to router
• Wait for it to reboot
• Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.

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

→ 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.

• 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

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

The default network configuration is:

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.

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:
