The Belkin series of wireless LAN network adapters - both USB and PC Card (with PCI adapter that accepts the PC Card) - do their jobs capably, providing a quick painless way to get any Windows computer up and running on an 802.11b WLAN.

USB Adapter: F5D6050
Notebook Network Card: F5D6020
PCI Adapter: F5D6000

Whether you have a desktop or a notebook, whether you don't mind opening the case or don't want any part of it, Belkin offers a suitable wireless 802.11 adapter. The Belkin family of wireless adapters offers excellent performance and features, and simple set up so you'll have a wireless network up and running fast.


  • Excellent documentation
  • Supports 128-bit WEP


  • None

Basic Features

The $109 Wireless Notebook Network Card is a standard Type II CardBus card. Our main complaint is the design of the antenna, which is basically a full-width extension of the card sheathed in black plastic with an unmarked amber LED for link and network activity. Functionally it's fine. (For those who prefer it, Belkin also offers a $49 PCI-based adapter that works in conjunction with the Wireless Card, or you can buy the two in a bundle for $164 direct from the company Web site.)

The stylish $109 USB adapter doesn't require a separate power supply since it gets its juice from the USB port. It uses dual adjustable antennas, while a single LED denotes both power and network activity. The unit comes with a 6-foot USB device cable.

The USB unit has sturdy rubber feet so it stays where you put it, but a nice touch is the inclusion of screw-mount points on the underside in case you want to attach it to a wall. Mounting hardware is not included, so you must supply your own screws.

Both the notebook card and the USB adapter support 64- and 128-bit WEP encryption for security. I was able to successfully use both devices, with 128-bit encryption enabled, to connect to an 802.11b access point from another vendor.

Driver support is provided for Windows 98, Me, NT, 2000, and XP. Belkin also furnishes all of the products with 24/7 technical support and a lifetime warranty.


I installed the Wireless Network Card and the Wireless USB Adapter into a notebook running Windows 2000. Both devices were correctly identified upon installation, and I was prompted to insert the CD for the drivers to be copied. The setup utility comes next; it runs the products' respective configuration utilities, which appear in the Windows system tray. (Using the PCI adapter requires the additional step of doing the physical driver installation for that device before performing the above process.)

The configuration utility lets you change any number of 802.11 parameters, including the mode (Ad-Hoc or Infrastructure), SSID, or the transmit rate. You can also use the utility to set up 64- or 128-bit encryption.


I tested the performance of the Belkin Wireless Notebook PC Card against another product in the family, the Belkin Wireless Access Point.

The performance was very good, and perhaps more importantly, speeds were stable and consistent as well. Generally speaking, the performance did not degrade as I put distance (and floors) between the client and the access point. Enabling full 128-bit WEP encryption only impacted performance minimally.

TCP throughput using the Belkin Access Point averaged about 4.3Mbps throughout our range of conditions with encryption turned off. UDP Throughput was slightly lower, at around 3.7Mbps. When I activated 128-bit WEP, TCP Throughput maintained its previous level without missing a beat, but the UDP Throughput scores dropped slightly to 3.1Mbps.

Testing the adapters in Ad Hoc mode (sans access point) without WEP enabled I got a TCP throughput of 3.8Mbps from client to client.


Considering how easy the Belkin Wireless Adapters are to set up, that's reason alone to consider them. However, factor in the excellent docs, support, and performance, and the Belkin family of 802.11 wireless adapters is a worthy addition to your network.
