Dlink DSL-502T fails to save DMZ

Damn Dlink.

Trying to update the firmware because the DMZ setting was not saving or at least was being reset to disabled despite my best efforts to save it into the modem. A restart seemed to be ok, but a while later the DMZ was disabled again.

So I downloaded the most recent firware and used the upload option to install it. I then did the reset via the pinhole button on the rear and boom!

Power LED comes on but no-one is home any more. The damn thing has trashed itself internally. In this location I had a spare and replaced it straight away which gets the site back on the internet, etc. But what pain that is when a simple firmware update blows up the modem.

So why was it not saving the DMZ. Guess I’ll never know.
