Compact USB 2.0 Wi-Fi adapter

The JinTaoRui RTL8188 is a mini wireless USB 2.0 adapter that adds 2.4 GHz connectivity to desktops or laptops lacking built-in Wi-Fi. It uses the Realtek 8188 chipset and supports IEEE 802.11 n, g and b standards for a peak throughput of 150 Mbps. The device fits any free USB 2.0 port and works with Windows, Mac OS X and Linux.

Security button and dual modes

A hardware QSS button enables quick WPS setup for 64-bit or 128-bit WEP, WPA, WPA2 and WPA-PSK/WPA2-PSK encryption without typing long passphrases. The adapter operates in Infrastructure mode for standard router connections or Ad-Hoc mode for direct device-to-device links. CCA technology automatically selects the clearest of the 13 available channels to reduce interference.

Suits basic wireless needs

This adapter suits users who need simple 2.4 GHz wireless access for web browsing, email or light streaming on older or headless systems. It does not support 5 GHz bands, higher 802.11 ac or ax speeds, or external antennas, so buyers who want dual-band performance, gigabit-class throughput or extended range should look at something else.

Questions about this item

Will the RTL8188 chipset need driver updates or replacement as operating systems evolve?

The adapter uses the Realtek 8188 chipset with drivers for Windows XP through 10, Mac OS X and Linux; future OS releases may require updated drivers from Realtek.

What limits throughput first during continuous transfers — the USB 2.0 link or the 150 Mbps wireless rate?

The 150 Mbps wireless ceiling is reached before the USB 2.0 interface becomes a bottleneck.

How warm does the mini USB 2.0 adapter get and does it draw extra power when running all day?

The compact design has no active cooling; it draws standard USB 2.0 bus power and stays warm to the touch under sustained load.
