How to Set Up a Bridge on a Linksys WRT300N

By Dustin Thornton

A wireless bridge is a device that allows you to effectively extend the range of your wireless signal. A wireless bridge works by receiving the wireless signal from a router connected to the Internet, then re-broadcasting the signal to other computers that would not normally be in range of the original wireless network. Turn your WRT300N into a wireless bridge by installing the DD-WRT firmware and changing the router configuration.

Things You'll Need

  • DD-WRT flash utility
  • Second wireless router

Install DD-WRT Firmware

Step 1

Connect your computer to the number "1" port on the Linksys WRT300N using an Ethernet cable. Disconnect any other computers from the router; only the cable or DSL modem may be connected.

Step 2

Download the DD-WRT v24 flash utility.

Step 3

Press and hold the small "Reset" button on the back of the WRT300N with the tip of a pen or pencil. Hold the button for approximately 30 seconds. This performs a hard reset on the router.

Step 4

Click "Start" and click on the "Control Panel." Choose "Network and Internet," then click "Network and Sharing Center." Click "Change adapter settings" in the left pane.

Step 5

Right-click the active internet connection and select "Properties." Highlight "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties."

Step 6

Enter "" as the IP address and "" as the subnet mask. Click "OK" to save the changes.

Step 7

Open your Internet browser and type "" into the address bar and press "Enter." This accesses your router configuration panel. Input "admin" (lowercase) as the username and password.

Step 8

Click the "Administration" tab at the top of the window, then click "Firmware Upgrade" below it. Click "Browse," then navigate to the DD-WRT v24 flash utility you saved on your computer. Click "Upgrade."

Step 9

Unplug the router from the wall outlet, once the firmware installation is complete. Leave it unplugged for five minutes.

Step 10

Reconnect the router and perform another hard reset by pressing the "Reset" button on the back of the router for approximately 30 seconds.

Step 11

Enter back into the "Internet Protocol Version 4 (TCP/IPv4)" properties and select "Obtain an IP address automatically."

Configure Bridge

Step 1

Open your browser and enter "" to access the router configuration page. Input "admin" for the username and password.

Step 2

Click the "Wireless" tab and select "Basic Settings." Change the "Wireless Mode" setting to "Client Bridge."

Step 3

Input the name of your other wireless router (connecting to the Internet) into the "Wireless Network Name (SSID)" field. Click "Apply."

Step 4

Click the "Wireless Security" tab and set the security of the bridge device to the exact security settings of the wireless router connecting to the internet. For example, if your main wireless router uses WPA security, set the bridge to WPA security. Click "Apply" to save your settings.

Step 5

Click "Setup" and change the "Local IP Address" to "" (provided the main wireless router is configured to "") and the "Subnet Mask" to "".

Step 6

Change the "Gateway" and "Local DNS" to the same setting as your main wireless router. Click "Apply" and exit the router configuration page.
