Hello. I purchased this item the day before yesterday and had it set up via the WPS button method. It worked fine, and I followed the instructions to a T. Recently, however, I noticed that the device started to have all four of its LEDs blink eratically. I also noticed that it was making this subtle noise, not loud or anything, but it's very noticeable if you sit next to the outlet that it is plugged into. I also realized that the extended network name no longer showed up in the connection list. I've tried plugging it into other outlets, but the blinking and buzzing didn't stop. I've tried to reset it, but that hasn't seemed to work either.
