Just go into your devise manager and it should tell you weather or not you have a card or not. If not obvisly yes you will have to buy a card if you want wireless (which I rahter have wired, but thats what a laptop is for no wires
) Anyways if you do have a network card I reccomend you go with Linksys. I have never had a problem with them EVER. I have owned a router for 8 years now (ever since I was 8) and I love that thing. Even know I modded it over the years with uncaping and unregistrated (to clean tracks (you dont need to know about what this dose or even need it)). Anyways taht is all my suggestions, I hope these help.
