Netis Systems 150 Mbps Wireless-N USB Adapter WF-2103

What the WF-2103 is

The Netis Systems WF-2103 is a USB wireless adapter that adds 2.4 GHz Wi-Fi to desktops and laptops lacking a built-in radio. It suits home users who need a simple way to join an existing Wireless-N network for everyday tasks such as web browsing, email and standard-definition video streaming.

Practical limits of the Wireless-N interface

The adapter follows the IEEE 802.11b, 802.11g and 802.11n standards and operates only on the 2.4 GHz band, so it cannot use the 5 GHz channels that many modern routers prefer for higher throughput. Peak link speed is capped at 150 Mbps, and real-world rates will be lower when walls, interference or distance weaken the signal.

Capacity and headroom

At its rated 150 Mbps the device provides enough bandwidth for music downloads, file sharing and standard-definition video streaming on a single connection. It will run out of headroom when multiple users stream high-definition video simultaneously or when large file transfers demand sustained rates above the Wireless-N ceiling. Security is handled through 64/128-bit WEP, WPA and WPA2 modes, with WPS available for quick pairing.
