The $149 Linksys
Wireless-G Access Point
is the market leader’s offering in the burgeoning
market for products based on the still-draft 802.11g specification.

Like the Buffalo AirStation and Apple AirPort Extreme Base Station routers
I recently looked at, the Linksys Wireless-G Access Point uses the Broadcom
wireless chipset.

Unlike those two products, however, the Linksys eschews an internal antenna
in favor of a more conventional dual external antenna arrangement. The presence
of external antennae obviates the need for the connector that the Buffalo and
Apple product offer, though the Linksys antennae can be both rotated and removed.
The use of external antennas also seemed to help performance somewhat compared
to the other products, which we’ll see in a moment.

As the wall is often the best place to mount WLAN access point, Linksys includes
a wall bracket that also can be used to facilitate stacking of other Linksys
products (which of course use the same chassis).

Linksys offers a Windows-based utility to perform initial configuration of
the access point which works quite well, but its use is not mandatory, since
you can go directly to the Web-based interface if you so prefer.

The Web-based configuration screens use Linksys’ familiar and well-designed
tabbed interface and offer a typical compliment of features. After the initial
setup, you can choose to do things like disable the SSID broadcast, enable MAC
filtering, backup the access point’s configuration settings, or restore the
unit to factory default settings (much more convenient than dealing with the
recessed rear button or looking up the vendor’s specific reset procedure.)

One characteristic of the WAP54G that I particularly like is the fact that
some of configuration changes do not require a reboot of the access point to
take effect. This includes things like changing the unit’s IP address or enabling
MAC filtering. It’s a refreshing change from some units that require restarts
after even minor configuration tweaks.

One configuration tweak that I’d like to see in the WAP54G but that is absent–at
least for the moment–is the ability to turn off or reduce the power of the
unit’s transmitter.

Another (albeit minor) convenience item–the Web-based configuration provides
a link to the PDF product manual located on the Linksys Website. This is of
course handy when you don’t have (that is, you can’t find) the CD, though I
admit you may never actually need to consult the manual.

The WAP54G does have logging capability. You can view the logs online or send
them to a specific PC (by IP address), but the data is not in Syslog format
so you’ll need to download a proprietary Linksys utility to do so. The WAP54G
also supports SNMP for network monitoring.

Like other Broadcom chipset-based products, the WAP54G supports two performance
modes–‘G only’ and ‘mixed’, the latter of which is designed to accommodate
802.11b clients. The preponderance of the WAP54G performance testing took place
in the ‘G only mode’ (with the related WPC54G Wireless-G Notebook Adapter, reviewed
separately).

In this mode, the throughput of the WAP54G was indeed impressive, particularly
at close range. At 10 feet, for example, the throughput yield was 21.51 Mbps.
This is significantly higher than any of the three previous 802.11g devices
I looked at, which were all in the 14 Mbps neighborhood at this distance.

As distance increased the WAP54G’s advantage began to diminish, and by the
time I was 75 feet from the unit I was observing throughput numbers equivalent
to or less than comparable products. Indeed, at 100 feet and greater, the Linksys
posted numbers well below the D-Link DI-624, though still significantly better
than the Apple AirPort Extreme Base Station with its internal antenna.

When I inquired with Linksys about their apparent performance advantage and
requested an explanation, they demurred citing the proprietary nature of the
product. That didn’t sit too well with me, but given that the WAP54G is only
an access point and the other 802.11g products I’ve tested were routers as well,
this is not an entirely apples-to-apples comparison.

Of course, a big concern with any 802.11g product at this point is compatibility
and interoperability due to the still-evolving nature of the specification and
the sometimes divergent implementations of this specification by the vendors.

Despite the performance differences, compatibility did not seem to suffer.
I was able to successfully associate and communicate with the WAP54G using both
802.11b- and 802.11g-based NICs from D-Link and Buffalo.

Linksys remains one of the more ubiquitous WLAN vendors for the home and SOHO
markets, and with products like the WAP54G, it’s not difficult to understand
why. It delivers convenient setup and administration and very good performance
(especially at close range). Though finalization of the 802.11g specification
remains a ways off, the Linksys WAP54G represents an excellent choice for those
who need performance now.
