Mercusys MA20N AC650 Nano Wireless Dual Band USB Adapter

The Mercusys MA20N transforms any Windows computer into a wireless-capable device with AC650 dual band technology. This compact USB adapter delivers combined speeds up to 433 Mbps on 5 GHz and 200 Mbps on 2.4 GHz, providing reliable connectivity for browsing, streaming, and online work.

Dual Band Wireless Performance

Operating on both 5 GHz and 2.4 GHz frequencies, this adapter supports IEEE 802.11ac/a/n/g/b wireless standards. The 5 GHz band offers faster speeds with less interference, ideal for bandwidth-intensive tasks, while the 2.4 GHz band provides better range and compatibility with older networks.

Ultra-Compact Nano Design

Measuring just 14.94x7.19x19.15mm, the MA20N is smaller than a standard USB flash drive. Once plugged into your USB 2.0 port, it sits nearly flush with your device, making it perfect for laptops where you want a permanent wireless solution without the bulk of traditional adapters.

Plug and Play Installation

Windows 10 and 11 users benefit from built-in driver support, eliminating the need for manual software installation. Simply insert the adapter into an available USB 2.0 port and connect to your wireless network immediately.

WPA3 Security Protection

The MA20N supports the latest WPA3-SAE encryption standard alongside WPA/PSK and WPA2-PSK, providing enhanced protection for your wireless connection and personal data against unauthorized access.
