I would like to upgrade the firmware on my D-link 604 router to the latest revision.
But in case I have a problem with the new firmware, can I protect my self by backing up the present version before upgrade, to install back if necessary.
Or if I have to, is there a way to reset back to the present version after installing the new revision..
The present firmware in 3.38 and the newest is 3.51
Your assistance would be very much appreciated
