300Mbps High Gain Wireless USB Adapter
MW300UH
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.
Regular Adapter
High gain adapter
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.
Plug and Play
With the built-in inbox driver by Windows operation systems, you just need to plug this adapter into the computer and then enjoy the fast wireless network in seconds.
Operating System
Compatible with Windows 11/10/8.1/8/7/XP(32/64 bit)
1 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.
2 To ensure compatibility, you may need to update the adapter’s drivers after an OS update. You can find our latest drivers in the download center at http://www.mercusys.com/en/support.
3 Use of WPA3 requires APs to also support the corresponding feature. This feature may only be used on Windows 11/10 (32/64 bit). To use WPA3, you may need to upgrade the drivers which can be downloaded on the official website.
Actual network speed may be limited by the rate of the product's Ethernet WAN or LAN port, the rate supported by the network cable, Internet service provider factors and other environmental conditions.
