how to network 3 computers in wireless network

 i have 3 pc's. one w/xp - one w/vista- one w/windows 2000.
I use dsl ( at&t-sbc yahoo). I have an external modem. I have bought a wireless nic for each computer.
I have a linksys wireless access point ( dsl port on it).
Do i need to buy a router/switch still? to network the computers together?

you can jsut connect the wireless acess point to the DSL.

and then all the pc's will connect to that.

oh actualy i'm wrong.

a acess point is not a router so it will not work!!!

sorry me not reading the question correctly
Aaron StreetInfrastructure ManagerCommented:
a router will allow three computers with internal IP addresses to share the single external ip addres your IPS will give you.

Ove course if your ISP gives you more than one ipaddress you could in theroy use an access point with out a router. but unless you do have at least 5 ipaddresses (you need at least 2 more addresses than you have devices) then you would need a router to connect all three to the network.

The only other way to do it is to have one PC connected to the internet. and then enable internet sharing for the other two to use. (i dont recomend this way, and not jsut becasue that pc would need to be on all the time for the others to access the internet)

thank you
do I still need to use access point when I get router?
and if not- can I anyways - just to get experience of using one?
thanks again

yes of course. IF yo have a wired router you would need to. but if not you could jsut use the wireless on the router as this will be an access point. However you could jsut hard wire the access point in to the router to do the same thing...

but yes a wire less adsl router is a router/modem and access point all in one
