USB 2.0 Wireless N Adapter 802.11n 150Mbps 2.4GHz

Compact 802.11n USB Wi-Fi Adapter for Desktop and Laptop

The USB wireless N adapter adds 802.11n connectivity to a desktop PC or laptop through a USB 2.0 port. It operates on the 2.4 GHz band at up to 150 Mbps with 1T1R single-stream technology. The mini form factor plugs directly into a port and keeps a low profile.

The adapter uses a Realtek RTL8188 series chipset and supports IEEE 802.11b/g/n standards. It handles WEP, WPA, and WPA2 encryption for legacy and modern networks. The internal antenna delivers indoor ranges up to 100 metres and outdoor ranges up to 300 metres in open space.

Driver support covers Windows, macOS, and Linux distributions. The USB 2.0 interface supplies power and data over one connection, so no external supply is needed. The device works as a client station for home, office, and point-of-sale terminals that lack built-in Wi-Fi.

Channel width options include 20 MHz and 40 MHz, which let the adapter trade throughput against co-channel interference in dense 2.4 GHz environments. Modulation spans BPSK, QPSK, 16-QAM, and 64-QAM under 802.11n. The adapter carries CE, FCC, and RoHS certification for procurement screening.

Why Choose the USB Wi-Fi Adapter

• Adds wireless capability to desktops and POS terminals without opening the chassis.

• The 2.4 GHz band penetrates walls and floors better than 5 GHz for basic office coverage.

• Bus-powered design removes the need for a separate power adapter at the counter or desk.

• Legacy WEP and WPA support keeps older access points connected during staged upgrades.

• The mini housing travels easily between machines for field technicians and temporary setups.

• Certification across CE, FCC, and RoHS simplifies procurement paperwork for regulated sites.
