See a comparison diagram of the different wireless technologies.

Wireless networks are rapidly becoming more popular and coming down in price. Since they don't require cables, you can use the devices anywhere in an office or home, even out on the patio. There's no need to roll out an Ethernet network cable to each room of a house; you can network anywhere -- without wires. Outside of the home, wireless networking is available in hotspots at coffee shops, businesses, airports -- great when you're on the road and need to get some work done. For convenience, wireless networking is the answer.

What Wireless Standard is Right for Me?
Now that you've decided to create a wireless network, the next step is to figure out which wireless standard to use.

Basically, a standard is a set of specifications for a device. All devices that follow a specific standard share operating characteristics, such as the radio frequency used and maximum data transfer speed.

For wireless networking, there are three standards to choose from at this time:

  • 802.11b
  • 802.11a
  • 802.11g
  • 802.11a/g

This problem was not mentioned anywhere in Linksys' online support, but from my research, it was a known problem.

I have a SOHO that uses a wired 10/100 switched network. Already part of this network is a Linksys single port Cable / DSL Router. When it came time to make the jump to wireless, the WAP54G seemed the logical choice, as I would not have to reconfigure anything on my existing network. For my initial conversions, I was converting a desktop PC and an older laptop. For this review, I'll be discussing at the WUSB54G. Look for reviews on all these items posted separately.

I decided on the WUSB54G because I did not have any available internal slots. This computer may be replaced in a year or two, and unplugging the network card from a USB port seemed a lot more attractive than opening the case. Actually, the installation is almost a simple as plugging the adapter into an available USB port.

My initial installation was using Version 2.0 of the installation software. The significance of that will be explained later. Regardless of your version of Windows, I suggest installing the software first. This will eliminate any potential problems in the installation process. Make sure you know your network name and WEP Key. You will need to supply that information during installation or you will not be able to connect right away. If you don't have the key handy, it can be input later, but it is not as convenient.

The Wizard does a good job of walking you through each step. Once done, you will need to reboot. Don't disconnect from the wired network just yet. Wait until the next phase is completed. On boot, you computer should detect the new hardware and install the correct drivers for it. The next step could take a while, so be patient. Your new wireless network card will search for a signal, an access point, and you should be prompted when a network is found.

First, the hardware. The Linksys WUSB54G wi-fi adapter comes in the form of a small box with a flip-up antenna. You hook the included USB cable (A-B type) to the adapter and to a USB port on your PC -- high-speed USB 2 port preferred -- and you can surf the web wirelessly. The adapter seems average in performance, in terms of speed and distance. (I use it with a Linksys Wireless-G router.) The signal strength seems to fluctuate quite wildly, even when you don't change any of the factors that might affect it. But overall, it works.

Now comes a BIG warning: do NOT install the utility that came with the adapter. It has a confirmed serious memory leak problem. By this I mean that after running the utility (which sits in the system tray) for about an hour, it'll have gobbled up anywhere between 300MB and 600MB (or more) of your system memory! My desktop has 1GB and at one point the utility took over more than 580MB before I shut it down via the Task Manager. Unfortunately (as another example of really bad software engineering), you can't quit the program for real. As long as you have the adapter active, the utility will come back to life and start eating up your memory again.

If you have Windows XP, use the OS's built-in "Windows Zero Configuration Wireless Client." First, uninstall the Linksys utility if you already installed it. Second, you need to install the adapter's driver: simply plug the adapter into a USB port, and, when Windows' driver search dialog comes up, browse to the "Driver" folder on the Linksys CD-ROM (e.g., "D:\driver"), and use the "v4" (version 4) driver, which is the latest -- after that, Windows' built-in wi-fi client will automatically kick in.

As a long time fan of LinkSys, with some exceptions on early versions, I upgraded my WUSB12 (802.11b) to their equivalent WUSB54G (802.11g/b).The upgrade was trivial, in part, because I was familiar with the language, technology and simily products.

When buying wireless equipment from any vendor keep in mind that the version number for the hardware and software is as important as the model number. In this case, the software CD came with an obsolete version 1.0, while a downloaded version 2.0 was available online. The earlier version would not work with hidden SSID's

As with many LinkSys products, which are build using real computer chips and open-source operating systems, they produce some heat. To minimize the negative consequences of heat use the chimney effect. I always mount units vertically, and if possible with with air under the unit. Keep the unit coooool, and like all equipment, it will last forever.

Another issue is that the range of wireless depends very strongly on the enviroment, not just the vendor. In one room, local hot-spots, no more than a few inches in diameter, producd a 10 dB change in sensitivity (3:1 in signal strength). The best location for my WUSB54g turned out to be on the side of the monitor, where internal metal at the correct distance acted as a corner reflector, significantly amplifying the signal.

Using the LinkSys WRT54G as the base station, I got about 35 dB signal-to-noise ratio providing 54Mbps bandwidth going through at least 4 very solid walls with wood not metal lath. Antennas on both the base and remote station need not only to be positioned wisely but also oriented along the same axis.
