Also i don't know what release is better to install. The latest? or a previous one? As i need the router to handle multiple VLan's and NAT (no wireless, no vpn etc..), is mini enough?
This router has a web cfe, so you can hold reset button down, keep holding and power up the router until pings start replying to 192.168.1.1. use the web interface to reset nvram and upload the firmware. I used a .bin and it worked. I used an old mini that someone linked in the wiki, then went to a new k3x mega build with the dd-wrt web interface and used the popup to also reset nvram.
