I am moving very soon and will need to set up a wireless router at my apartment. I will have cable high-speed internet service but, because of where my cable connection is, I will be setting up a wireless router. Anything that I should know?? I'm pretty clueless with that. I have a desktop PC. Based on mky limited research, I was thinking that I will get a Linksys Wireless-G router and the applicable wireless network card. Is that it?? What about PCI vs. USB for hooking up the wireless adaptor??
