Set the DD-WRT based D-Link DIR-300 ver. B as a Repeater Bridge

Original link here: http://jgiam.com/2012/07/06/setting-up-a-repeater-bridge-with-dd-wrt-and-d-link-dir-600/wp-admin/install.php

Here are the steps I did (adapted from the DD-WRT Wiki). My primary router is configured with WPA2 AES. The secondary router is running DD-WRT build 14311. The latest build in the DD-WRT router database, build 14896, is buggy.

Restore Factory Defaults on Secondary (DD-WRT) Router
Connect your computer to the secondary router via wired LAN port.
Open the address http://192.168.1.1 in your web browser. Newer versions of DD-WRT will require you to set a password before you can continue.
Open the Wireless -> Basic Settings tab
- Physical Interface Section
  - Wireless Mode : Repeater Bridge
  - Wireless Network Mode : Must Match Primary Router
  - Wireless Network Name(SSID) : Must Match Primary Router exactly including exact case- Make sure you spell this correctly
  - Wireless Channel : Must Match Primary Router (This will disappear once you put it in RB mode, and isn’t needed)
  - Wireless SSID Broadcast : Enable
  - Network Configuration : Bridged
- Save
Open the Wireless -> Wireless Security tab
- Physical Interface Section
  - Security Mode : Must Match Primary Router and DD-wrt only works reliably with WEP or WPA2-AES
  - WPA Algorithms : Must Match Primary Router
  - WPA Shared Key : Must Match Primary Router
  - Key Renewal Interval (in seconds) : Leave default
- Save
Open the Setup -> Basic Setup tab
- Connection Type will be: Disabled
- Set STP for Disabled (Enabled sometimes can cause connection problems) redhawk
- IP Address : 192.168.1.2 (Assuming Primary Router IP is 192.168.1.1)
- Mask : 255.255.255.0
- Gateway: 192.168.1.1 (again assuming Primary Router IP is 192.168.1.1)
- DHCP Server: Disable
- Local DNS: 192.168.1.1 (if IP of Primary Router is 192.168.1.1)
- Assign WAN Port to Switch : Optionally enable this to use the WAN port as another LAN port.
- Save
Open Setup -> Advanced Routing tab
- Set Operating mode to “Router”
- Save
Open Services
- Disable Dnsmasq
- Save
Open the Security -> Firewall tab
- Uncheck all boxes…except Filter Multicast
- Disable SPI firewall
- APPLY Settings
Reboot the router.
