Two High Gain 5dBi Antennas Leads to Maximized Range
MW300UH has two high-gain external antennas to ensure stronger signal transmission and reception, which helps users to gain a stable Wi-Fi connection across their home.

Desktop Design Greatly Avoids Signal Blocking
The cable makes it easy to find a spot for MW300UH in your workplace. Moreover, compared to the slot-inserted adapters, this design allow you to put it nearer to the router, in which way it can receive stronger signals.
