Introduction
Thank you for purchasing the NetComm Wireless NP920 Dual Band WiFi USB Adapter. This manual illustrates how to set up
and configure your Dual Band WiFi USB Adapter.
Overview
The NP920 is an industrial wireless 802.11a/b/g/n dual band USB adapter which enables data transmission speeds up to
150Mbps for 20MHz and 300Mbps for 40MHz. As new bandwidth intensive applications become more common, higher
wireless LAN throughput is needed. The NP920 Dual Band WiFi USB Adapter adopts MIMO technology and 2.4 GHz IEEE
draft 802.11n wireless technology to dramatically increase the overall throughput of the wireless LAN by supporting link rates
as high as 300 Mbps - an improvement of nearly six times the throughput of standard 802.11g. The NP920 is also
interoperable with standard 802.11a, 802.11b and 802.11g devices, and fully supports industry standard compliant security
and Quality of Service (QoS).
Features
802.11n dual band WiFi (2.4GHz and 5GHz)
Plug and play with no setup. Simply search for 2.4GHz and 5GHz networks and enter the relevant security
password
