BuffaloTech 54 Mbps Wireless USB 2.0 Keychain Adapter
| Summary | Flash-stick-style USB 2.0 802.11g client adapter that carries and installs its own driver and client manager application. Supports Buffalo’s AOSS auto-install system |
| Update | None |
| Pros | 鈥?Leave the install disk at home 鈥?Virtually no throughput hit with WEP or WPA |
| Cons | 鈥?Client Utility doesn’t cooperate with Zero Config 鈥?Installs on some Windows versions can be confusing |
Buffalo Technology’s WLI-U2-KG54-AI 54Mbps Wireless USB 2.0 Keychain Adapter distinguishes itself from the rest of the "keychain" or "USB flash-key" styled wireless adapters by being the first to automatically install its drivers and Client Utility when first connected to a Windows computer.
The AI is also the first Buffalo product to be based on a chipset from Taiwan-based RaLink, the RT2500 USB to be exact. It’s also the second Buffalo 11g product to not use a chipset from Broadcom. (The first was the WLI-USB-G54 which converted from Broadcom to Conexant PRISM back in March.)

The AI’s white plastic package is about the size of a disposable butane lighter, but somewhat slimmer. It has a wireless activity (ACT) indicator that lights only during transmission, a tiny recessed switch to disable the auto-installation feature and a feature that should allow you to attach a lanyard or tiny keychain ring, neither of which is included. Buffalo does throw in a USB extender cable for use with hard-to-reach or too-closely-spaced USB ports.
