Hard reset instructions for Netgear WNR3500Lv1

If your WNR3500Lv1 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. Other scenarios where you might want to reset your router is if you've forgotten the password or misconfigured it and can't get access anymore.
Your can reset your Netgear WNR3500Lv1 in the following way(s):

With a sharp pen or paper clip, press down the Restore Factory Settings button and hold it for about 7 seconds
When the power light starts to blink you can release the reset button and wait for the router to start up
The power light will be solid (not blinking) once the router is started.

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

This process usually works for resetting any router to it's factory setting.
