Product information

Description

The Mercusys MW300UM N300 Wireless Mini USB Adapter provides wireless connectivity for PCs and laptops with a maximum data transfer rate of 300 Mbit/s. Supporting IEEE 802.11b/g/n (Wi‑Fi 4) on the 2.4 GHz band, this compact USB adapter enables stable internet access and can be used in desktop or mobile scenarios. Its soft AP function can turn a computer with a wired connection into a Wi‑Fi hotspot.

Advantages

Compact, plug‑and‑play design fits any USB port and is convenient for travel. Supports up to 300 Mbps on the 2.4 GHz band for reliable web browsing and basic streaming. Soft AP mode allows the adapter to create a wireless hotspot from an existing wired connection. Compatible with common networking standards IEEE 802.11b/g/n and available in a discreet black finish.

Suitable for

Upgrading a desktop or laptop without built‑in Wi‑Fi
Adding wireless access to a small office or home workstation
Creating a temporary Wi‑Fi hotspot via soft AP on a wired PC
Basic internet browsing, email, and SD video streaming

Maximum data transfer rate: 300 Mbit/s
Wireless standards: IEEE 802.11b/g/n (Wi‑Fi 4)

How to use

Insert the MW300UM into an available USB port on your PC or laptop. Install drivers if prompted by your operating system or use the provided driver package. After installation, select the desired wireless network from the system Wi‑Fi list and enter the network password. To enable soft AP mode, open the adapter utility or settings and activate the access point feature, configuring SSID and security as required.

Usage recommendations

Place the adapter in a USB port with minimal obstructions to the main router and avoid locations with heavy 2.4 GHz interference.
