Hi,
There is a new firmware, now 2.02 is the latest release. ftp://ftp.dlink.com//Multimedia/dns320/Firmware/dns320_FW_202 I am not sure if this will fix your problem, but I have not noticed anyone having a similar problem to yours with it. There are a number of improvements, but a few glitches have been reported. You might want to scan the forum for some of the complaints and realize that you cannot go back to 2.00 once you upgrade. The only other thing I can think of is to wonder if you are waiting until the save process is complete and that little saving circle disappears before you reboot. I doubt that is the problem but I just mention it. Good luck
