You will first need to download this file for the flashing.

  1. Go into the linksys stock firmware and choose to reset to defaults.
  2. Once that is finished, set a static ip on your machine to with subnet and gateway

  6. When you are in dd-wrt's webgui, go to Administration > Factory Defaults
