It's 2.4GHz only, no 5GHz. Max WiFi speed is 300Mbps using 802.11n. It has 2 detachable 5dBi antennas on the back, so you can swap them for bigger ones if you want more range. With normal antennas, it adds about 1-2 rooms of coverage. Good for pushing signal to back bedroom, balcony, toilet, or shop corner where your main router can't reach.
