Wireless Networking at Better Than Wired Speeds!

The Wireless-G Notebook Adapter with SRX400 is the simple way to add or
upgrade wireless connectivity in your notebook computer. Just slide it into your
notebook's PC Card slot and enjoy high-speed wireless network access while
retaining true mobility.

The Wireless-G Notebook Adapter with SRX400 combines smart antenna
technology with standards-based Wireless-G (802.11g) networking. By overlaying
the signals of two Wireless-G compatible radios, the “Multiple In, Multiple Out”
(MIMO) technology effectively doubles the data rate. Unlike ordinary wireless
networking technologies that are confused by signal reflections, MIMO actually
uses these reflections to increase the range and reduce “dead spots” in the
wireless coverage area. The robust signal travels farther, maintaining wireless
connections up to 3 times farther than standard Wireless-G.

With SRX, the farther away you are, the more speed advantage you get, and
SRX400 works great with standard Wireless-G and -B equipment, and other flavors
of Linksys SRX. But when both ends of the wireless link are SRX400, the network can
increase the throughput even more by using twice as much radio band, yielding
speeds up to 10 times as fast as standard Wireless-G—faster than
10/100 wired network speeds! But unlike other speed-enhanced technologies,
SRX400 can dynamically enable this double-speed mode for SRX400 devices,
while still connecting to non-SRX400 wireless devices at their respective fastest
speeds. And SRX400 is a “good neighbor”, always checking for other wireless
devices in the area before gobbling up the radio band.

Once you're connected, you can keep in touch with your e-mail, access the
Internet, and share files and other resources such as printers and network storage
with other computers on the network, wherever you wander. At home, you can
surf the web or use instant messaging to chat with friends while sitting out on the
patio. You'll also be able to connect with any of the growing number of public
hotspots springing up in coffee shops, airport lounges, hotels and convention
centers. Your wireless connection is protected by industrial-strength WPA
encryption. The included Setup Wizard will walk you through configuring the
adapter to your network's settings, step by step.
