I’ve heard about possible security problems with the new wireless networks. Is this rumor true? What do you think of these networks?

A. When you configure them properly, wireless networks work through a NIC's media access control (MAC) address. This setup makes any network secure because the wireless hub recognizes only registered NICs. However, I've seen wireless networks configured to work on other cards—a practice that puts network security at risk.

Configuring your network to use a MAC address is quick and easy. Take the time to set up your wireless network properly. When you do, the only disadvantage of such networks is transfer speed: The maximum speed of 11Mbps is slow by modern standards. Hence, wireless networks are best suited for home networks—which, by the way, usually suffer from lax setup standards.
