After seeing the unusually high price tag of a Microsoft Xbox 360 Wireless Adapter, I almost had a heart attack. $99.99 retail. Let me say it again, FREAKING $99.99; is Microsoft out of their mind? I mean, routers and wireless adapters cost much less than that! Luckily, there is a way to create an adapter with a La Fonera wireless router.

Basically, the La Fonera is loaded with a third party firmware called DD-WRT. The firmware allows you to put the Fonera into client bridge mode. This basically lets the Fonera connect to your home wireless network and pass that data through the ethernet port to your Xbox. Its kind of like one of these Linksys gaming adapters, but cheaper and with more capabilities.

Here’s the full guide:

NOTE: You must have a La Fonera with DD-WRT firmware loaded onto it before this will work. If you need help installing DD-WRT to the Fonera, see the guides here
