It is extremely important to follow the guidelines for your specific router. Please see Installation for more information. Remember to follow the peacock thread first for background [1], use this page to identify your router model correctly, and use the dd-wrt download search page (DD-WRT Downloads page or secure version) to ensure that you are getting the correct file (or files, as often is required) for the job.
