welcome to dal the online computer help forum
as you are running xp home on your computers they should recognise the wireless connection straight away with out any problems
but that is not to say that you wont get any because not every thing works first time
i would say it would be a good idea to set up your system and see what happens if you get problems post them in this thread and i or somebody else will have a look at it for you but you might be ok
what works for one person can be a bitch to another especially pc's
if you need further info please shout me
hope this helps
