I bought it from Amazon in 3210rs. Its a dual band ADSL2+Modem router. There are two fixed antennas for good coverage. It supports 802.11ac. It has a usb port. Build quality is very good and it is lightwieght. Installation is very easy and does its job very well. I was able to get 3 bars in next room with obstical. If I use a repeater, I get signals even outside of my apartment. Good value for money product.
