Linksys WPC54GS notebook adapter with SpeedBooster
The Linksys WPC54GS notebook adapter with SpeedBooster adds extra speed to the already fast data rates of 802.11g and is Linksys's answer to the speed-enhanced and the . In order to take full advantage of the WPC54GS's speed-enhancement feature, however, you'll need to pair it with . The WPC54G also works with standard 802.11g and 802.11b gear, but it scales down its data rate to match these devices' slower data rates. With good security features and a low price of around $50, the WPC54GS is a bargain, and it's an excellent means of adding Wi-Fi to a laptop, especially if you plan to use your laptop with other SpeedBooster devices. However, if you already have speed-enhanced equipment from another vendor, we suggest that you stick with that brand so that you can take advantage of the increased data rates throughout your network.
Setting up the Linksys WPC54GS notebook adapter with SpeedBooster is fool-proof. The adapter comes with a printed quick-installation guide that walks you through the process, which consists of installing the software on the accompanying CD and inserting the PC Card into your laptop. This takes about two minutes. The guide also gives you instructions on how to disable the Wireless Zero Configuration tool built into Windows XP so that you can use Linksys's Wireless Network Monitor to configure the WPC54GS. You can use either utility to manage the WPC54GS, but we recommend that you use Linksys's configuration tool because it provides more granular information about available network connections. For example, the Linksys Wireless Network Monitor lets you see the operating channels of neighboring networks, which can help you avoid interference by identifying a less crowded channel for your own network.
The WPC54GS includes support for WEP and WPA encryption. This makes the adapter both backward compatible with networks using older and weaker WEP encryption and forward compatible with networks that have already moved, or plan to move, to the newer and stronger WPA encryption scheme.
The WPC54GS uses Broadcom's Afterburner technology for its speed enhancements. Afterburner has both advantages and disadvantages compared with the Atheros-based speed enhancements in the D-Link DWL-G650 and the Netgear WG511T. In terms of raw performance, Atheros delivers better results with regard to both throughput and range. But the Atheros solution relies on channel bonding, which uses a wide swath of spectrum and is more apt to create interference for neighboring networks than Linksys's SpeedBooster products are. The SpeedBooster, a.k.a. Afterburner, solution enhances speed while limiting itself to a single nonoverlapping channel, which makes it a good alternative if you live in a dorm or an apartment building with neighboring wireless networks.
