Hack Attack: Turn your $60 router into a $600 router - Lifehacker

Of all the great DIY projects at this year’s Maker Faire, the one project that really caught my eye involved converting a regular old $60 router into a powerful, highly configurable $600 router. The router has an interesting history, but all you really need to know is that the special sauce lies in embedding Linux in your router. I found this project especially attractive because: 1) It’s easy, and 2) it’s totally free.
