When a Wireless Client (Card) needs to be installed on a Network device that is Not a computer, there is No way to install software drivers.
As a first step (years ago) industry added to Access Points a Client Mode (The Linksys WAP11 had such a mode).
When GameBoxes came out and Wireless connection was desired by consumers, the industry decided to cash on the need for Driverless Wireless cards, and to make it simple started to sell GameBox Wireless Cards and called them Consumer Bridge/GameBox Wireless adapters.
Well the expectation was that since this is Not a real full-grown Access Point it would be inexpensive.
Marketing genius decided differently and they are actually as or more expensive than Access Points.
Access Points, as oppose the the puny plastic GameBox cards, are capable to be configured to Wireless Modes, many time have a stronger Radio, and a replaceable External Antenna.
Overall it a much better designed and capable Wireless Device than the gamebox thingies.

Linksys, Buffalo, as well as few others, for a similar price to game box cards (usually $50 to $80) combined a Client Access Point with a Switch so you can Bridge Wirelessly and plug few wired computers at the remote location connected Wireless to the main Wireless Router.

In addition, when it was discovered that Linksys, Buffalo, Microsoft (when they use to sell them), and few other vendors are using an open source based firmware for their Wireless Router, and that it is possible to replace the firmware with a 3rd party one, an industry of 3rd party open source firmware started to emerge.
The 3rd party providers re-programmed the firmware and added many more features including a capacity to configure the Wireless Routers to work as Clients (GameBox Wireless card) and have the 4 ports switch as well.
Now the fun started. I.e. you could find an inexpensive Wireless Router (or a good used one on eBay), flash it with 3party free firmware, and have a "Wireless Party"
As an example, I have few Buffalo Routers that cost me at the time $29.99 all flashed with DD-WRT firmware and work 10 times better than the double priced regular GameBox Wireless cards.
In wireless terms, it translates to better distance, and faster more stable wireless network connection.
Alas at the moment these cheappos are not on market.

As is the Buffalo motioned before works as Wireless client with a switch.
Otherwise find a deal on any of the hardware that you like and it is mentioned in the following page, download the firmware, Flash and enjoy.
