In 1999 Apple introduced AirPort -
an affordable and easy-to-use solution for accessing the
Internet without restrictive cables. In 2003, AirPort Extreme
incorporated 802.11g wireless standards. In 2004, Apple released
AirPort Express, using the 802.11g wireless standard to
provide up to 54 Mbps data rates. It supports both Macs equipped
with an AirPort Extreme Card and Wi-Fi-compliant 802.11g Windows
PCs, as well as Macs with the older AirPort Card and 802.11b
Windows PCs. AirPort Express also provides simultaneous wireless
Internet access via your DSL or cable modem for up to 10

(AirPort Base Station
reliability problem -2001)
A reader recently told us about a reliability problem with AirPort
Base Stations that started to surface in Jan 2001. In some units,
the capacitors in the power supply overheat and fail, causing the
AirPort to continually reboot. The bad news is that this problem
tends to crop up after the AirPort Base's warranty expires.
Apple is not admitting to a design problem, and will only repair in-warranty
units (with normal repair charges).
You can read this
thread in Apple's Discussion Groups... although it's mostly
"me too"s... (you'll need to register first...no purchase
required) for more info.
Thanks to those of you who wrote to tell me your experiences with setting
up an Airport in a Windows-only network. It looks like Apple has
not done anything to prevent using the Airport Bridge in Windows-only
networks. It appears that Windows-only setup problems may be due to the Karlbridge
software's inability to access the NAT and DHCP controls of the
Airport Base station. If you connect the Airport base station
into a network that already has a NAT router or DHCP server, you may
have problems, especially if you set your wireless clients to use DHCP
to obtain their IP address information.

The Apple Airport Access Point CAN
be used with Windows-based PCs. The Apple product is basically the
same thing as the Lucent WaveLAN Access Point (Lucent is now calling
the WaveLan products Orinoco). But
the Lucent Access Point management tool will not allow configuration
of the Apple Airport.
So you would think you would have
to have a Macintosh to configure the Airport base station, right?
Luckily, the Airport contains a 486 processor running the Karlnet
Karlbridge software. So you can go to the Karlnet
WWW site and download
http://www.karlnet.com/download/configsetup.exe, which allows you to configure all
aspects of the Airport Base Station - from a Windows computer! Since the Airport
Base Station is $500 cheaper than the equivalent WaveLan product,
this is significant!
Connecting it up
If you are using only wireless cards to connect your computers, you
can plug the cable modem LAN port into the Airport Base station directly
(you may need to use a "crossover
cable" instead of a normal UTP cable. Otherwise, just
plug the Airport Base Station into your hub. If your sharing
method includes a DHCP server, set the Airport Base Station to obtain
its address info via DHCP. Otherwise, you'll need to assign
The Airport Base Station has built-in
NAT and DHCP servers. So just set your wireless station cards
to obtain their IP address information automatically and you should
be in business.
I use Compaq-branded
11 Mbps station cards ($199.00/ea) in each of my laptops.
Since both the Compaq and Airport are 802.11b compliant 11 Mbps wireless
products, I am able to surf the net with ease, no wires attached.
The Airport takes care of assigning IP addresses, DNS addresses, etc.
for the laptops. The Airport also handles all of the NAT translation.
that you can use wireless adapters other than the Compaq cards.
Just make sure you get 802.11b compliant products. See
this page for product
listings and links.
Also note that the Airport Base Station is a Bridge and
NAT router. So the wireless and Ethernet-connected parts of your
network should be able to talk to each other without problems.
Sevy has a Java-based configurator that handles both the
ORiNOCO/Agere RG1000 and Apple Airport. Check out the other Airport
utilities, too! [Thnx Joe Prickett!]

is a VisualBasic based utility written by Rop Gonggrijp for setting
up the Apple Airport Base Station. The program allows access to
configuration of the modem, the Wireless NIC, bridge/router configurations,
DHCP (both client and server), WEP settings, Access rights by MAC

configuration sets on disk for later use.
[Thnx to Ren Roderick for the tip!]

various 802.11b Windows network adapters with the Airport base station,
