Configuring an Apple Airport Mesh Network

I have recently been installing a Wi-Fi network at a lakeside community about 40 miles from Manahattan where cable broadband recently became available. I decided to use an Apple Airport Extreme base station with amplifier and antenna, and use Airport Express APs as relay and remote APs. Here are some comments and questions that might be useful: Apple Refers to an Airport Network with Multiple APs as a Wireless Distribution System (WDS). Is this a Mesh Network? Can less expensive APs also be used in an Apple WDS? Well sort of. According to NYCwireless President Dana Spiegel: ”WDS is a form of mesh networking, but requires manual setup and doesn’t easily do auto-discovery (two things that are generally important). The Linksys AP (if it supports 802.11g) should also be able to use WDS just fine, though its configuration will be a little different. Generally, WDS requires 3 bits of info: 1) wireless channel (all of the linked APs must be using the same channel) 2) network name/ssid (all of the linked APs must use the same ssid) 3) MAC address of linked APs (each AP must have the MAC addresses of the APs that will connect to it via WDS).” Are there any tricks to configuring an Apple Airport Network? Indeed. First, resist the temptation to avoid reading the manual and think that you can just figure out how to set up a network with multiple APs simply by using Apple’s excellent Mac/Windows AirPort Configuration Utility. I especially reccomend AirPort Networks for Windows available on Apple’s Website. Second, for those who will insist on setting up the network anyway without RTFM, remember that within the Airport Configuration Utility Apple calls the MAC address the “Airport ID,” presumably to avoid confusing MAC with “Mac” as a shorthand for their Macintosh computers. Before I read the instructions, I assumed the Airport ID was the SSID, and couldn’t understand why the bloody things didn’t work. Ugh! Finally, remember that as you add APs in an Aiport WDS there’s a big differences between a Remote AP and a Relay AP. Suppose it’s the getting toward the end of the day, you want to stop fussing with all this network stuff and go for a dip in the lake. You decide to configure one last AP as a Relay station, anticipating adding additional stations on another day. Big mistake. A Relay AP, of course is always looking for its friendly AP down the line to pass its signal to, and if it doesn’t find it it gets so flummoxed that it will take the entire network down. Those who RTFM are spared this surprise. I’ve read all about WifiDog on nycwireless, and I want it with my WDS. How can I integrate my Airport WDS with the Dog? Good question! I’m looking for answers and help with this. 

One thought on “Configuring an Apple Airport Mesh Network”

  1. Hi. I’m trying to set up a WDS using all Apple Airports in a mixed mac/PC environment. This is a new project, but I have set up a WDS network once before years ago. I get the WDS main, relay and remote distinction, but now I’m finding that in Airport Utility, when I look at my Airport Extreme running 7.6.1 there is no longer a WDS option, just “create a wireless network” and “extend a wireless network”. What’s up with that? My older airport expresses don’t do 11n, so they can’t “extend” they just have WDS.
