I recently ran into this problem and decided to share my successful results. This was my problem, I wanted to extend my wireless internet. But I wanted to do more than that. I wanted to extend my wireless internet and have my second router to have Ethernet capabilities. Here’s what I had to work with and what I did.
I have an Apple Extreme (1st Generation) directly hooked up to the cable modem. I am using the Apple Extreme to 1) distribute wireless internet and 2) connect my desktop computer via Ethernet. This is a great setup. I plan on upgrading to the 2TB Time Capsule at some point but for now, I love this setup!

Apple WDS Network
Now I have an Airport Express (amazing little unit) in my living room. I use this guy to connect my desktop computer’s iTunes and use Airplay for wireless music. Again, this is an awesome setup. If you don’t have a great wireless setup in your living situation, this is one to setup!
Recently, I purchased an Apple TV (yes, I love Apple products) and I wanted to use this in my living room. In order to do that, I needed the Ethernet port on my Airport Express to be active. Now, I’m not an Apple Genius or a networking Guru by any means, hence part of the reason of this post…so I can remember how to do this again in the future. The only way to extend internet and enabling the Ethernet is to participate in a WDS Network (Wireless Distribution System).
Ok, enough of the back story details, here are the settings that I used to get my WDS to work and love Apple products even more!
Note 1: Before getting started, if you’re running OS X Lion, download Airport Utility (AU) 5.6 in order to customize your Airport settings.
Note 2: It’s easier if you know the MAC address of each unit before you begin. This number is listed when you start up Airport Utility on the Airport Summary page – Airport ID. It’s also located on the bottom of each unit.
Airport Extreme (Main Unit)
Base Station Tab:
- I have “Allow setup over WAN” unselected.
Wireless Tab:
- Wireless Mode: Select “Participate in a WDS Network”
- Check “Allow this network to be extneded”
- Radio Mode: 802.11n (8802.11 b/g compatible
- Channel: 6 (your preference, but it didn’t work when I chose channel 1)
- WireLess Network Options: I chose 11 Mbps Multicast Rate and Transmit Power 100%. WPA Group Key Timeout at 1 hour.
WDS
- Select WDS Main
- Select “Allow wireless clients”
-
- Enter the MAC ID of the Relay or Remote device(s)
- Click Update (Don’t worry about the other WDS modes)
That did it for this unit. On to the next device.
Airport Express (Remote Device)
Wireless Tab
- Wireless Mode: Select “Participate in a WDS network”
- Choose the Wireless network name that you have configured in your Main device. It’s important to choose the same Radio Mode, Channel, and Security Password information as the Main device
WDS Tab
- WDS Mode: Select “WDS Remote”
- Select “Allow wireless clients”
-
- WDS Main: Enter the MAC ID of your Main Device (for me, it was my Airport Extreme)
- Leave the other WDS Mode’s alone and click on Update
You should be Rocking and Rolling!!! This is exciting! Now you have a wireless system that extends your Ethernet capabilities to another room or area and extends your wireless internet. Hope this helped you more than the other web pages out there. I was hoping to find someone to map it out for me but this took me a few hours of trial and error before I had success. Hopefully this limits your time spent to less than what I did.
I would highly recommend exporting your config settings on each device in case you ever upgrade or have to reset your devices.
Cheers!
