SKU CH-6KVY-2XR3A

A compact USB 2.0 wireless adapter delivering 150 Mbps on 2.4 GHz with WPA2 encryption and WPS support

  • 150 Mbps wireless speed for fast data transfers
  • USB 2.0 interface for broad desktop compatibility
  • Supports 802.11n and 802.11a/g protocols for flexible connectivity
  • 64/128-bit WEP and WPA/WPA2 encryption for secure networks
  • Mini design enables easy portability and simple setup

Mini USB Wi-Fi adapter for desktop users

The XFN0399 plugs into a USB 2.0 port and adds 2.4 GHz wireless networking to a desktop without built-in Wi-Fi. It supports 802.11n, 802.11g and 802.11b standards at up to 150 Mbps. The compact external design makes it simple to carry and install.

Limited to 2.4 GHz band and USB 2.0 throughput

The adapter operates only on the 2.4 GHz frequency and connects through USB 2.0, so real-world speed is capped by that interface. It cannot use 5 GHz channels or newer Wi-Fi protocols such as 802.11ac or 802.11ax. Maximum link rate stays at 150 Mbps with 20 MHz or 40 MHz channel width.

Handles basic browsing and streaming.

The 150 Mbps rate is enough for web browsing, email and standard-definition video. It supports WEP, WPA-PSK, WPA2-PSK and WPS encryption for secure connections. Heavy file transfers, 4K streaming or low-latency gaming will exceed the available bandwidth and the single-band radio.

Questions about this item

Should I pick the 150Mbps version or a faster one?

The adapter is rated at 150Mbps wireless transmission rate. It matches the 802.11n standard listed and suits basic browsing or streaming on the 2.4GHz band.

What does the 150Mbps figure mean in daily use?

That is the maximum wireless link speed. Real throughput will be lower due to overhead, distance and interference, but it is sufficient for typical web, email and SD video tasks.

Does the USB 2.0 interface limit the 150Mbps speed?

The adapter uses a USB 2.0 connector. The port's 2.0 signalling handles the adapter's 150Mbps wireless rate without bottlenecking it.
