Any way to reset via admin interface?

I have been having connection issues with this router. It´s pretty much new (a few weeks old), it was working fine but then a few days ago it started with random disconnections. The internet doesn´t drop permanently, but when doing a ping test through a CMD window I get random ¨request timed out¨ errors, which reflects in the browing too. I wanted to do a full reset on the router and a firmware update but it doesn´t work. pressing the reset button on the device itself does nothing, once it boots back up all the settings are still there, wifi network, password settings, etc.... nothing resets. I´ve tried holding for longer, holding while power off and back on, etc.... but all it does it shut down and boot back up. I am wondering if there is any way to reset it without the button but via the admin interface on routerlogin. I just want it back to factory settings to see if that corrects the disconnection issues. 

Thanks!
