The Fritz!Box 3490 is a fast and powerful router that offers great speed over both 802.11n and 802.11ac. It's the fastest Fritz!Box I've used, and is much better value for money than many of AVM's previous models.
It should be said that the software is great too and, while I think it looks a tad bland compared with the nifty design used on Asus' routers, for example, it's fast and full of features.
