Hello All -

I currently have an AP which I am trying to extend the range on.  Here's what I have to work with:

Primary Route (AP)
-  Running DDWRT (Newest build)
-  WAN Port to DSL
- AP Set up broadcasting SSID
- WPA2 Personal Encryption

I have a 2nd router also running DDWRT which I'm trying to use to extend the signal.  I'd prefer to keep the extension the same as the original SSID so it would be seamless if possible.  Here's what I've tried:

- Setting it up as a Repeater Bridge - Worked as far as providing network to physical ports, but didn't seem to extend range of wifi as documentation suggests
- Setting up as Repeater
 -  I set the Phy wifi int to match same as primary AP
 - Then configured VInt. with new SSID
 -  Set AP to be on diff subnet.
Never saw it broadcast even though broadcast SSID was enabled

Again, I'm trying to find the best way to extend the range of my WiFI while keeping the same SSID if possible.

Please suggest any thoughhts or options - Thanks!

What you want is called Wirless Distribution Service (WDS), which establishes a WiFi backbone link between a WDS endpoint (your second DDWRT box) and another part of the same wireless network (e.g., your main DDWRT). This lets you expand the networks range using multiple access points without using a Cat54 or fiber optic backbone. The WDS endpoint AP can accept wireless clients while simultaneously managing its WiFi backbone line, but you do experience some loss of throughput.

There's a detailed document discussing WDS at dd-wrt.com:

http://www.dd-wrt.com/wiki/index.php/WDS_Linked_router_network

In a nutshell, you just configure your first (central) AP as "WDS AP", and the second as "WDS Station". The SSIDs and encryption settings must match on both devices.
