At the moment I have a D-Link 5 port switch connecting 5 PCs, I want to add my 2Mb connection to the 5 computers and yes I know I could do it via a wired Router. I am not because in the near future I will be buying a laptop and don't want to be constricted to a wire. So I want this wireless network to share my internet connection to all these computers and the future laptop.
Hopefully you are aware that nearly all Wi-Fi routers are equipped with wired ports as well (no insult to your intelligence intended if you already know this). Would make use of as many wired connections as the topology and layout would permit, and avoid PCI/USB Wi-Fi for the stationary machines if at all possible (understandable if connectivity is needed in an alternate location not readily accessible with ethernet cable).
Edit: in retrospect, failed to mention that if several "group" (2+ machines within a small area) locations are needed, a pair (or more, as requited) of WRT54G/GS routers with an alternate firmware in client or WDS mode function quite nicely, as they allow multiple wired ethernet connections at a given point with only a single wireless client connection - this often proves more inexpensive than adding wireless access to each client separately, and often yields better connection results as the WRT54x line is powered externally.
Wired connections will typically allow more throughput and stability than most wireless connection.
Also, you might consider just purchasing a decent Wi-Fi router now (personally, would suggest the WRT54G/GS, as they are near commercial level products), and couple it with the current switch for as many wired ports as may be required.
Chances are whatever mobile machine is purchased in the future will have 802.11g (or greater) integrated.

I only need the internet part shared as I won't be using the LAN part, as explained above.
I may be misunderstanding the intention of the above comment, but local connectivity (that is, connection to other local machines) will not play a significant role in Wi-Fi equipment selection.
