Compex WL54G wireless PC Card adapter
The Compex iWavePort WL54G mixes a quick-and-easy setup with second-rate security. Still, at $40, this wireless adapter card undercuts the better-performing and the by about $20. The WL54G's most distinguishing trait is a tiny connector on the adapter's tip that allows you to attach an external antenna for increased range.
Getting the WL54G online is a snap. A one-minute CD-based driver installation holds your hand through the setup and configuration of the card. The card comes with a printed quick-install guide and a CD containing drivers, as well as a thorough 30-page electronic manual. Based on an Intersil Prism Nitro radio, the WL54G PC Card sticks out 1.3 inches and has LEDs for link, which shows whether you have a connection, and activity, which shows whether packets are being transmitted to or from the card.
Unfortunately, the WL54G lags in terms of security, with only 64- and 128-bit wired equivalent privacy (WEP) encryption rather than the more advanced and secure Wi-Fi protected access (WPA) security. Compex is working on adding this vital security feature and says it will post an update on its Web site in the coming weeks.
In tests at CNET Labs, the card was able to move 24.2Mbps in a pure 802.11g environment, a rate that falls to a disappointing 11.3Mbps in a mixed environment. Over the course of a week of informal testing, it worked with three different wireless routers from Compex, Hawking, and Linksys, but as of mid-October, the card still lacked Wi-Fi certification, so compatibility could be sketchy with some devices.
As its benchmark, CNET Labs uses NetIQ's Chariot 4.3 software on a console system with clients running NetIQ's Performance End Points 4.4. Our throughput tests measure the transfer speed of a file that a user might send across the network. This is known as the payload throughput and does not include packet errors and other data that might be transferred over a network. Payload throughput can vary widely from the bandwidth speeds vendors advertise and is a much better gauge of what you're likely to experience with a standard file transfer.
