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. |

Flash Layout
Please check out the article Flash.Layout. It contains an example and a couple of explanations.
OEM easy installation
| https://wiki.openwrt.org/lib/images/smileys/fixme.gif 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.
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 | Latest OpenWrt release (NOTE: Name must contain "tftp") |
| TFTP Transfer Window | FILL-IN seconds |
| TFTP Window Start | approximately FILL-IN seconds after power on |

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
cd /tmp/
wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc
cd /tmp/
wget http://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 | Enabled |
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 |
