I inherited an Apple Airport Extreme from a friend of a friend, but already had a Linksys WRT320N that was working fine (well, after much hair pulling). I was initially going to use the Airport for shared network storage, but that proved too buggy to be of any real use. Since the WRT320N isn’t simultaneous dual-band, I decided to use the Apple to add a second, 5GHz + N only wireless network to my setup. Here’s how my setup looks:
- WRT320N (running DD-WRT): Handling DHCP; running 5GHz wireless N-only network
- Airport Extreme: Access Point; running 2.4 GHz N/G mixed network
Here’s how I did it. First I changed the WRT320N to broadcast 5GHz + N-only, and I appended “-5ghz” to the SSID (so it reads like network-name-5ghz). Only a few of my devices can take advantage of that, but I mostly wanted it for faster wireless gaming on my XBOX 360.
Then I got the airport up and running as an access point. Here are the key settings to do that. You first need to download and install Apple’s Airport Utility (the latest version is 5.5.2, as of this writing). Once you’ve added the device to your network and the Airport Utility recognizes it, go to Manual Setup, which is a button at the bottom. Note: If you need help with the initial setup, here is Apple’s user guide.
AirPort section
- Wireless tab: Create a wireless network here. In my case, I set the Radio Mode to “802.11n (b/g compatible)”. This allows all of my non-N and/or non-5 GHz devices to access a wireless network. I gave it the same name as my 5 GHz network, except I dropped -5ghz off the end.
Internet section
- Internet connection tab: Connect Using should be set to “Ethernet” and Connection Sharing should be set to “Off (Bridge Mode)”.
- TCP/IP tab: I did configure IPv4 “Using DHCP” but you can manually assign an IP address, too (My WRT320N hands out IPs, some of which I make static for port forwarding purposes).
That’s it! This should allow you to have your Airport Extreme act as an Access Point, and broadcast a second, uniquely-named wireless network. I’ve noticed a significant reduce in lag and latency using 5GHz for XBOX Live, and since the networks are on different frequencies (5GHz vs. 2.4GHz), the signals don’t interfere with each other.
Note: My iPad and Gateway laptop are the only other devices that can “see” my N 5GHz-only network. A lot of wireless N adapters can only do 2.4 GHz, sadly, so they get relegated to the AirPort’s mixed network.

Did you connect the Airport Extreme to the Linksys Wireless N network via WDS? Or did you connect the two via Ethernet?
Hi Vik,
The setup goes something like this:
1. Cable modem is plugged into the WAN port on the Linksys
2. One of the LAN ports on the Linksys is plugged into the WAN port on the Airport
3. The Airport is setup to be an access point, and simply receives its settings from the Linksys.
4. The Linksys and Airport each broadcast a unique wireless network (SSID)
Does that help clarify?
