Building a Wireless Mesh Network
I. INSTALL DD-WRT FIRMWARE INTO THE LINKSYS WRT54GL
ROUTER
The DD-WRT firmware provide us a lot more features than the original Linksys WRT54GL
router firmware.
To install DD-WRT firmware, we will need to download two firmware versions: mini and
standard. The mini version is due to some limitations imposed by the Linksys firmware where
you can only upload the firmware with a certain maximum size. This mini version doesn't have
OLSR, after flashing it to mini version we will need to flash it again with the standard version.
We will use v24-sp1 version.
IMPORTANT: Flashing the Linksys WRT54GL Router with DD-WRT will void the warranty.
Making a mistake flashing the device can render it unusable.
We will use the following hardware and software.
HARDWARE:
1. 02x Linksys WRT54GL wireless router
2. 02x Laptop
3. 02x Ethernet Cable
SOFTWARE:
1. Internet Explorer or Mozilla Firefox
2. dd-wrt.v24_mini_generic.bin
3. dd-wrt.v24_std_generic.bin
In addition, we will have to take the following precautions before install DD-RWT:
Disable all firewalls, anti-virus software, and wireless connections on the PC.
Do NOT use a wireless connection to upload firmware instead of it use a wired
connection.
Do NOT flash/backup your firmware over an https connection, use http.
Plug the blue Ethernet (Cat5/RJ45) cable that came with your router into the Network
Interface Card (NIC) on the back of your computer and into one of the ports labeled 1, 2,
3, or 4.
The “Internet” port on your router should be connected to your broadband source i.e.
cable or DSL modem.

1. Download the firmware images.
In order to upgrade the Linksys firmware, we have to go the next web site: http://www.dd-
wrt.com/site/support/router-database and download the two image files (Fig. 2).
Fig. 1: Linksys Router Model
Fig. 2: Image files to download
2. Restore to the Factory Defaults the router WRT54GL.
First, connect the PC to the WRT54GL via Ethernet cable (ports labeled 1-4, not the WAN or
Internet port). Then, open Internet Explorer and navigate to 192.168.1.1. This will open the
Linksys web interface and ask you for a user and a password. If you cannot remember them,
press the Reset button for 30 seconds, with this action the username and the password will be
reset to its original (username: admin & password: admin).

2.3 DEMO
This will be the DEMO that you will have to implement the day of the evaluation. The next sections explain the procedure used to test the DEMO and verify that it’s working.
2.4 OLSR
Now, download and install olsrd-0.5.6, which is an implementation of the OLSR protocol. It
allows mesh routing for any network equipment and it is available for many operating systems.
