If you have somewhere to hide from this squeak, then buy safely. I asked around electronics stores, the same voltage adapter costs about half the price of a router. Therefore, I decided that I would take another in the same price category. With its pros. Inexpensive. Easy to set up. Great signal. All strips of reception. The speed did not cut on wi-fi. For my taste, beautiful. Cons below: The only downside that made me want to return it was the squeaky, whistling power adapter. In silence with him in the same room is not possible, respectively, and sleep.
