I own an ibook G3 600 Mhz. I wanted to connect it, since a long time, to the wireless router already installed at my home.
But I didn't want to purchase an airport card. I knew there were some solutions through one of the USB port.
So I tried (and purchased !! 
) many options (even the powerline option) ...
At last, I have find a solution and it works smoothly and moreover, it have been set up in my Ibook in less than 5 mn.
So, I offer you a wireless and economical solution to connect any Apple Macintosh (with at least Mac Os X 10.3.9) to a Wifi router with speed from 1 to 54 Mb. And... way, way..cheaper than an airport card.
The hardware I will sell you is not refurbished. It is totally brand new and comes directly from my wholesaler.
It is new.
But to save on shipping charges, I will discard all the "fluff" (packing, wrapping, etc..) and just send you the needed items:
As soon as you pay, I will ship to you, by secured mail postal service :
1. an USB adapter 802.11b / 802.11g - 11 to 54 Mbs (important: with an USB 1.0 port, speed will be limited to 11 Mbs max)
2. You will download from our web site the driver and a tutorial and tips to install and run smoothly your wifi adapter
3. 1 year of warranty of your hardware
You will get a 2 years warranty from the manufacturer (you see the big interest to register ? :-D ).
How does it run ?
Easy.
1. Before connecting the USB adapter, you must install the driver
(you will receive the direction of our web page where you can download the driver) .
2. Restart you Macintosh.
3. Plug the USB WIFI adapter
4. The driver seeks for the network and in some seconds, you will be connected.
With what Macintosh does this Wifi USb adapter work ?
It works with all Macintosh under Mac OS X (at less 10.3.9 and sup) with an open and free USB port.
This adapter won't work under Mac OS 9. We haven't tested it with OS X 10.2
What do you need to make it work ?
• a wifi router already set up (obviously).
This item is an adapter (as the original Airport M7600 card from Apple ) to connect to an Airport base or any wifi router. We don't sell the wifi router.
• Download from our web site and install the driver specific to the Mac OSX and this USB adapter.
You will double clic on the Driver and... it is installed.
>>>>> Step 2 <<<<<<<
When the wifi program have detected the wifi network, you have to set up your Network
in order that your Macintosh can detect a new peripheral, a new adapter...
>>>>> Step 3 <<<<<<<
Configure your TCP/IP network.
See explanations in our tutorial guide we have attached
with the driver you will download...
Done !
Just a little testimonial :
What are the benefits for you to purchase this wireless solution :
With the USB wire, you will have a better position of the antenna
You will definitively gain in signal strenghth comparing this adapter to the Airport card. At my home, there is 20 meters between the Wifi router and my ibook and even in this case, i don't have to put upper the adapter. It works perfectly near of my computer, on the table.
30 days of installation warranty or you get back your money.
If for any reason, you are not satisfied or it doesn't work as you wanted, please send us back the item as we shipped to you
and I refund your money, without questions !

Personal notes :
I can really assure you that I have searched during many times to find my actual solution.
For example, I have tried the BELKIN FD6050 (another USB adapter)... It works but after 15-20 mn, the driver "hang up". You have to reconnect.....
I purchased also a DLINK 122 but it also disconnects many times. And it is more expensive...
These are many USB manufacturers compatibles Mac OS X :
Asante - Belkin - D-Link - MacSense - NetGear - Proxim - Sagem - Syntax Buffalo
I have tested or read many on them.
I just want to give you an efficient solution. Sincerely !
You are also free to make your own investigations...
