Installing of OpenWrt for first time

openwrt-DVAG3810BN-squashfs-cfe.bin (this is a backfire 10.03rc4 image) works. Connect your computer to the WAN port and set the ip address in the 192.168.1.? network. Hold the reset button while powering on the router. Wait for the power light to stay a steady green. With a web browser (I use firefox on linux others should work i.e. internet explorer) go to and a firmware upgrade screen will appear. "Browse" to the firmware and click the "Update Software" to load the firmware. *NOTE*: If the power light stays red when it reboots you will have to repeat this procedure. It seems that the CFE loader loads the firmware at 0xbe400000 the first time it is run. The second time it loads at 0xbe010000 (the correct address).

If you have connected to the serial console you can use the CFE command line to load the firmware.

Upgrading OpenWrt

Use Luci System / Flash Firmware or use the console CFE or use the above installation procedure.

Original Firmware

You can download an older version of the original firmware from Extract the openrg.img file from the tar archive and use LuCI's system/flash firmware to install it. You can also use the Installing OpenWrt instructions to load the original firmware image file.

Switch Ports

Serial header pinout:

   |  o 1         o Ground

 h |  o 3         2 Vcc (3.3v)
 i |              3 Tx Data

Just remember that you can't hook up a PC serial port directly. You need a TTL level converter.


Needs Work.

Specific Configuration

Although LuCI sees the 5325 switch DO NOT use it to configure it. LuCI does not seem to connect to port 5 (the router). So if you update through LuCI you will lose connectivity to the router. Edit the /etc/config/network file instead.

To be able to use LuCI to configure the switch edit the /usr/lib/lua/luci/model/cbi/admin_network/vlan.lua file.
