Hard reset instructions for D-Link DSL-504T

If your DSL-504T router is not working as it should, dropping connections or not being responsive, you should first do a reset of the router to see if the problems persist.

Your can reset your D-Link DSL-504T in the following way(s):

Locate the reset button on the back off the router
While the unit is powered on, press the reset button with a sharp object (e.g. paperclip)

The 30-30-30 reset

If the above instructions don't work you can always try the 30-30-30 reset as follows:

When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp)
While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds
