I recently bought this router to replace a lost Linksys wireless router and so far it's working fine with some improved range. I, like about everyone else was TOTALLY annoyed with the blinking blue disco lights.FYI, after a brief search on the internet, I discovered this:"Note: The button on the back of the router is NOT a power switch. It is used only to turn the blue LED lights on the router on and off."I just assumed the switch in the back of the router was a power switch, but it's not.Thankfully, I can now enjoy the device without have to wear sunglasses at night.
