How To Setup Client Bridge

I have an old Linksys WRT54GL router flashed with an open-source firmware DD-WRT. One of the nice things you can do with DD-WRT is configure it as a client bridge. You can then use the client bridge to connect a computer with no wireless network interface to the network. This article was written to help me remember in the future how to setup a client bridge on a Linksys WRT54GL flashed with DD-WRT. The configuration details pertains more to me and may not necessarily work out for your setup. If you want a more complete instruction, check out the client bridge documentation available from DD-WRT’s website.

  1. Reset the router. Login. Set username and password.
  2. Go to Wireless > Wireless Security. Set security mode and key to match your AP.
  3. Go to Wireless > Basic. Set wireless mode to Client Bridge.
  4. The wireless mode and SSID should be the same as your AP.
  5. Go to Setup > Basic setup and manually set IP address.
  6. Set IP address to 10.10.10.12. Leave local DNS blank. Main router is 10.10.10.11.
  7. Go to Security > Firewall and disable SPI firewall and only multicast checked.
  8. Go to Setup > Advanced Routing. Change mode from gateway to router.
