After installing DD-WRT to whatever partition you install to just set up a quick, and easy password go to the services tab hit save at the bottom then reboot router. Now telnet to router, type erase nvram, and now type reboot. Now set all settings in DD-WRT only hitting the save button for each tab never hitting the apply settings button just reboot router at the end of set up. I seem to get a cleaner install this away.
Thanks to all the people that have put time and effort every day into DD-WRT which has in my opinion the better interface of any 3rd party firmware. Thanks to Brainslayer for all your hours after hours of coding to try, and make DD-WRT better each day.
