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 allows you to put it nearer to the router, in which way it can receive stronger signals.
Easy Setup
A friendly user interface on a CD for simple installation.
Operating System
Compatible with Windows 10/8.1/8/7/XP
*Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput and wireless coverage are not guaranteed and will vary as a result of 1) environmental factors, including building materials, physical objects, and obstacles, 2) network conditions, including local interference, volume and density of traffic, product location, network complexity, and network overhead, and 3) AP limitations, including rated performance, location, connection quality, and AP condition. *To ensure compatibility, you may need to update the adapter’s drivers after an OS update.
