text: I think Engineer there probably has done a good job of confusing you.  ALL laptops and I don't mean SOME, I mean ALL come with 802.11b/g cards.  Even if it had "n" in it it would be backwards compatible with b/g so you're fine.  Just get an 802.11b/g router like this D-Link, http://www.newegg.com/Product/Product.asp?Item=N82E16833127143 and it's only $16.  (Note: DSL or Cable only, these routers do not work with dial-up connections but hardly any of them do).\n\nIf you're looking for a guide on how to set up a network check out this how-to guide from Cnet, http://reviews.cnet.com/Cut_the_cords_with_a_Wi_Fi_network_Install_the_wireless_adapters/4660-10163_7-6248774.html
