How To: Use a pair of older Airport Extremes to build a Dual-Band network (802.11 N and G)
A handy guide to setting up a dual band wireless network without buying a brand spanking new Airport Extreme. Why would one want to do such a thing? Well, if you have a bunch of devices that can take advantage of 802.11N (MacBook Pro, Mac Mini) and a bunch that can only do 802.11G (iPhone 3G, MacBook, etc), then this will allow the -N devices to work to their full potential. Speed. I. Am. Speed.
It works so long as you happen to have a couple of the older Airport Extremes just hanging about the place, which in my case, I do – one-with-802.11N-and-Gigabit-LAN-that’s-one-model-older-than-the-current-Dual-Band-Airport-Extreme (heretofore referred to as The Newer One), and an-older-one-with-802.11N-but-only-10/100-LAN-Airport-Extreme (The Older One).
This How To ain’t mine. In fact, I owe it to Gruber at Daring Fireball for pointing me in the direction of this very useful guide by some unnamed chap at Luo.ma.
Hats off, Unnamed Chap!
As things have a habit of falling off the internet, I have archived a copy of Unnamed Chap’s post on this subject as a PDF. ‘Tis here.
