Buffalo AirStation Wireless USB Keychain Adapter

Getting online just got a whole lot easier with Buffalo's AirStation Wireless USB Keychain Adapter (WLI-U2-KG54-AI). Despite its cumbersome name, this keychain Wi-Fi adapter is small and light, and getting online with it is painless. The adapter is about the size of a pack of gum and weighs 0.6 ounce, making it lighter and thinner than Netgear's similar WG111 device. It even has a snap-on cover with a loop for attaching it to a neck strap or a keychain, although we doubt it will catch on as a fashion statement. For a hassle-free setup, the Buffalo keychain is a no-brainer, but those who demand high performance should get the Netgear WG111.

Inside the AirStation USB adapter is a Wi-Fi-certified 802.11b/g radio. The adapter comes with a 2-foot USB extension cord, a setup guide, a CD with software, and a 42-page electronic manual. The USB 2.0 device is powered through the USB port and is small enough that it doesn't block our notebook's empty USB slot above or below. It does stick out 3.75 inches, however, and nearly knocked over a coffee cup as we moved the notebook around. Security is adequate, with the choice of 64- or 128-bit WEP encryption or the stronger WPA security, with AES or TKIP encryption. You can upgrade the security to WPA2, but it lacks support for Cisco's LEAP security scheme, so it may be the wrong choice for connecting to some corporate networks. It's not available yet, but it should be by the end of summer. It may be available as a firmware upgrade.

With one of the quickest setup routines, the Buffalo AirStation Wireless USB Keychain Adapter offers three ways to connect to the Internet with a Windows XP computer; unfortunately, Buffalo supports only Windows 98 SE and newer operating systems, while ignoring Macintosh, NT 4.0, and Linux systems. The quickest route to the Internet is via Microsoft's Windows Zero Configuration interface, which doesn't require loading software from the CD--simply plug in the adapter to your USB port. For those who have a specially equipped Buffalo AirStation router , loading the software allows you to use the AirStation One Touch system (AOSS) to establish the connection. This step is redundant, as adapters are typically set to join the network right out of the box, but those new to networking may find it reassuring. Buffalo's Client Manager 2 software is simple to use and provides good connection data with any access point but lacks a histogram of network activity. Linksys and Hawking both offer this feature, and though it's not necessary, it's a nice extra for those who like to monitor their network's activity. The main screen has a signal-strength meter and information about your connection, as well as windows that allow you to survey available wireless LANs. The program also allows you to create network profiles, which you can use to easily switch between multiple network connections.
