Creating a Wi-Fi Internet hotspot service from scratch can seem like a daunting task. I had many sleepless nights trying to get to grips with FreeRadius, DD-WRT, Chillispot etc. I hope that this How To helps you to avoid some of the problems I encountered along the way.

********Warning ********

Following these instructions may invalidate your Linksys warranty. You do so at your own risk. These instructions assume that you have an understanding of Linux, PHP MySQL and Apache. If you brick your AP you might get it back by holding down the reset pin for 20 seconds, unplug the power while still holding down the reset button for another 20 seconds and then plugging the power back in while still keeping the reset button held in for a further 20 seconds. This should bring it back to the defaults of whatever firmware you have installed. You should be able to login to 192.168.1.1
