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.Three MiFi  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.

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.
