I also wanted to add that I did use the ASUS lash that changed the NVRAM size
"ASUS RT-N66U B1 Firmware Version 3.0.0.4.220 IMPORTANT, DUE TO THE NVRAM SIZE UPGRADE, CHANGE TO THIS VERSION FIRMWARE WILL WIPE ALL YOUR SETTING! AFTER UPGRADED FIRMWARE, PLEASE PRESS THE RESET BUTTON AND HOLD OVER 5 SECONDS TO RESET THE ROUTER TO DEFAULT."
Just so those who come along and see how I got it to work dont miss a step. I forgot to put that in my instructions above. I am also putting in a nice
instruction for bridging mode
Instructions
A very simple step-by-step description to connect a Router running selected DD-WRTV24 firmware in Repeater Bridge Mode. (This will work for almost everything, but do check notes on individual routers below clock).
If you are using a G router, use 12548 builds to create a wireless bridge. DO NOT USE SP1 OR THE MAY 24 08 BUILD.
This mode is NOT for WIRED connections between two routers! It is a wireless connection only.
To enable bridge mode between two routers, the primary router must be in AP mode (default) with DHCP Server enabled. The secondary router running DD-WRT v24 will be configured as the Repeater Bridge.
Restore Factory Defaults on Secondary (DD-WRT) Router
Do a proper HARD 30-30-30 Reset on the router.
Set your computer to a static IP of 192.168.1.9 if you know how to set static addresses. Otherwise leave your computer's network adaptor(s) programmed with the factory default setting of DHCP and the router will assign a valid address to your computer.
Connect your computer to the secondary router via wired LAN port or as a wireless client. The dd-wrt default wireless SSID is "dd-wrt"
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
Virtual Interfaces Section
Add
Wireless Network Name(SSID) : Different from Primary Router
[NOTE] - You CAN try using the same SSID but it usually will not work properly. Many have had random disconnects and/or no connection if the SSID's are the same.
Wireless SSID Broadcast : Enable
AP Isolation : Disable
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
Virtual Interfaces Section (note if you don't see this section your firmware should be atleast v24-sp2)
Security Mode : Must Match Physical Interface
WPA Algorithms : Must Match Physical Interface
WPA Shared Key : Must Match Physical Interface
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
Log back into the router at it's new IP address of
http://192.168.1.2
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.
Once you have it working, go to the wireless security tab, and set the same type of security AND key for both the primary and the repeater ssids and hit apply. Avoid WPA2 Personal MIXED, as it will likely kill communication between the routers (see Security section below for more on this). WPA2 Personal is fine.
SET YOUR COMPUTER BACK TO AUTO IP AND AUTO DNS.
