How To Reset Linksys Router To Factory Default Settings 

Dope. Short, sweet and no bull

Does it need to be turned on or off before resetting?

By doing this will I lose anything I can’t get back, or will it simply lose the WiFi name and password?

I think that little piece right next to the reset button is what you use to reset it.

I just got one of these from some one who had it laying around , does it support wds ? I wanna put it in my room and wirelessly connect it to my main router so I can have stronger signal and my own password

I try but still power light blinking and no WiFi signal found on any device.

Prrrooobably shouldnt be showing off your routers MAC address on camera there bud.
