I have had the DIR655 for several months. When I first got it, I changed the passwords as good little boys are supposed to do. My network has moments where it appears to be saturated, where the work on one computer keeps the other from completing a connection, but since there are no good diagnostic tools for these types of problems, I have learned to live with it. The problem I noticed today is that my password on the router was reset to the default, which I would never do. I found this out accidentally when I couldn't log into the router with my password. By chance, I left the password blank, and ouila, I was into the router. I ran a few tests. I reset the passwords via the tools screen, and logged in with the entered password. I then went to the tools screen again, before I could do anything, the screen was replaced with one that had a message "Wait 20 seconds for settings to be made." When I pressed the continue button, it happened again. When I pressed the continue button a second time, I got a login screen. My password was rejected. Using an empty password was successful. I retried the process and could enter my new password. On that login screen, my new password worked. Then I opened the tools screen and the process began again. How do I permanently change my password and how do I keep this box from resetting itself to the default password? This situation is SERIOUSLY upsetting.
