I don?t know the level of your Network knowledge.
So, let start from the beginning.

The Wireless Solution.
Wireless LAN consists on two main components.
1. Access Point (A/P).
Access Point is the Main Transmitter/Receiver that mediate between your LAN, and main computer, to the rest of the Network. It is connected to the LAN?s Hub/Switch. It usually supports an excess of 100 clients.
2 . Wireless Client Card.
Wireless Client Card is the LAN card that you should install on your network computers.
Most Client cards are PCMCIA, which work very well with Laptops. For Desktop, it is usually better to use USB Wireless Card.
PCMCIA Wireless Cards with fixed antenna (stuck behind the PC) yields inferior results versus Flexible Antenna on a USB card.
If you don?t have an established Network with a Router, and a Switch. You need to buy Wireless Cable/DSL Router instead of the A/P. This contains a solution for Internet sharing as well as A/P.
Conventional Wisdom* claims that the combination Orinoco Gold (About $90) SMC Wireless Router (About $150) yield the best results.

There are no real big differences between the entry level Routers.

When it comes to Wireless your mileage may varied, there are too many environmental variables that are unique to each individual setting.
