It doesn't affect gameplay for me, and it really shouldn't. From a wireless standpoint you are only pushing packets across your LAN, and that will be insanely faster than any ISP can offer you on broadband. There will be some security concerns if you don't want your neighbors surfing on your broadband connection. Normally, if you turn on WEP, and use a good key, you won't have any problems. Linksys and Netgear are both good and affordable, however I'm partial to linksys. I'd be happy to answer any other questions you may have.. .just let me know. There are some pretty bright eggs on this forum, someone will be able to give you a hand if you have trouble reaching the skuzzster.
