Linksys home-networking equipment is known for its easy setup and low price, and the Linksys WPC11 Instant wireless network adapter is no exception. With an average selling price of $70, this card is a good value, especially considering its first-rate performance and 24/7 tech support. True, the documentation for this PC Card fails to give Windows XP users the hand-holding they deserve, and Linksys' stubborn refusal to offer warranties longer than one year is disappointing. But with the card's solid performance, low price, and great support, you have a winner.

Quick-installation guide.
When you insert the Linksys WPC11 Instant wireless network adapter into your laptop, Microsoft Windows detects the card automatically, pops up a dialog box, and asks for a driver disc. A handy quick-installation guide walks you through the setup, giving you the choice between infrastructure (router-based) and ad-hoc (peer-to-peer) modes. The 70-page user guide does a superb job ushering you screen by screen through every Windows 9x, NT, Me, and 2000 option for wireless network setup and configuration, going into considerable detail over obscure features such as preamble modes and RTC threshold values. You also get a meaty troubleshooting guide and glossary.

Windows XP users, however, are simply told to install their XP driver from the disc and to refer to their Windows XP documentation. There's some sense to this method; XP's own Wireless Network Connection utility provides all the features you need to configure the card. But given the wealth of the manual's clear, useful information in Linksys's own Instant Wireless Configuration Utility, it seems odd that the company omits any explanation of the often-confusing Windows XP utility. At the very least, the manual should instruct you to right-click the wireless network connection and select Properties/Wireless Networks/Configure to start the Windows utility.

The Linksys Instant Wireless Configuration Utility provides a more sensible aggregation of features than Windows XP's native version. Once you install the Linksys utility, the Windows taskbar sports a new wireless connection icon that glows green when there's a good connection. We found the Linksys utility's estimates of the current throughput rate overly optimistic, however, much like Windows' own Connection Status utility.

Well-organized tabs appear across the top of the configuration utility screen for Link Info, Configuration, Site Survey, Encryption, and Advanced features. The Configuration tab is particularly handy, as it lets you choose ad-hoc or infrastructure mode, the Service Set Identifier (SSID), and power-saving options all in one place. The Link Quality and Signal Strength readouts on the Link Info panel are also quite useful, and the Advanced features are so well explained within the manual that Windows XP users would do well to have a look, even though the options are arranged differently. Like most of its competitors, the Linksys WPC11 offers both 64- and 128-bit WEP encryption options.

The Linksys WPC11 Instant wireless network adapter delivered average performance, clocking in at 4.9Mbps on our throughput test. In informal range tests, the Linksys tied the Netgear WAB501 dual-band PC Card but came up just short of the mark set by the Proxim Orinoco World PC Card. Still, it should offer plenty of range for most home environments.

For practical throughput tests, CNET Labs uses NetIQ's Chariot 4.3 software as its benchmark. For wireless testing, the clients and the routers are set up to transmit at short ranges and at maximum signal strength. CNET Labs' response-time tests are also run with Chariot software using the TCP protocol. Response time measures how long it takes to send a request and receive a response over a network connection. Throughput and response time are probably the two most important indicators of user experience over a network.

Linksys's tech support runs the gamut. On the downside, you get a very short, one-year warranty on the card, which the company tries to make up for with its toll free, 24/7 phone support. In addition, the Linksys Web site provides e-mail support along with an enormous knowledge base and a large quantity of general information about networking.
