Specification :

Up to 300Mbps downlink and 150Mbps uplink faster speed, WS-WNP671N is a Wireless-N PCI Adapter with IEEE 802.11n (draft) compatible that is fully backward compatible with IEEE802.11g/b standards. Therefore, it is an ideal device for home and SOHO networking to share high speed internet connection, files, printers, and multimedia communications with the flexibility, speed and security you need.

The Wireless-N PCI Adapter installs in most desktop or server and lets you put your computer almost anywhere in the building. In order to solve weakness of wireless signal problem, enhanced MIMO technology enables you to very easily extend the range of your wireless network up to 3 times farther wireless range than regular IEEE802.11b/g standard.

This Wireless-N PCI Adapter comes with software drivers for the most popular Microsoft Windows operating systems and can be integrated into a larger network, running Windows XP, 2000, Vista in either Ad Hoc mode (without an Access Point) or Infrastructure mode (with an Access Point).

WEP encryption and Wi-Fi Protected Access (WPA), and further enhanced with 802.1x authentication security. With drivers and utility available for most commonly used Windows OS. The 2.4GHz 802.11n/g/b Wireless-N PCI Adapter is a truly solid-design networking device that provides you with the ultimate freedom of wireless networking anywhere.

A setup wizard is provided as the part of the web configuration utility. You can simply follow the step-by-step process to get your wireless-N PCI adapter configuration ready to run in few easy steps.

Infrastructure Mode Application Diagram
The AP Router establishes an infrastructure mode for networking between all wireless clients and Ethernet resources.
Wireless Ad-Hoc Application Diagram
The wireless Ad-hoc mode is established by several wireless clients, which have the same SSID and radio channel. The wireless USB/PCI/PC Card adapters can be used for such peer-to-peer communication mode.
