Using DD-WRT on an Asus RT-N16 router to share a 3 MIFI Internet connection on LAN
Yes a snappy title! I’ve spent so long getting this configuration to work that I have to save the info here for my own future reference.
I originally tried to use the latest firmwares and spent a couple of frustrating day’s trying to get it working. I eventually gave up and tried the specifically mentioned firmware below and it worked as expected.
DD-WRT is an open source firmware that can be installed on many different routers. It opens a whole world of possibilities and configuration options, turning a mediocre router in to something that could cost a lot more.
ASUS RT-N16 is a wireless router that is considered particularly good to use with DD-WRT, mainly because it has masses of internal memory which allows you to install the biggest versions of DD-WRT which gives you all the bells and whistles such as OpenVPN, USB support, Hotspot etc.
MIFI is a small portable Internet connected Access Point that connects via 3G/4G. Mine is provided by the 3 network and I can get better speeds using the MIFI than i can from my home ADSL connection. I use the MIFI as a backup internet connection or for when I’m away from home. I wanted a way to share that MIFI connection with my home wired LAN, and DD-WRT is the way to do it.
