• I use my wireless notebook on multiple networks. How can I connect to them without having to keep changing my network settings each time I switch networks?

Windows XP's built-in Wireless "Zero Configuration" utility and most client programs that come with wireless adapters allow you to establish multiple "profiles" for each network that you connect to. The profiles typically contain SSID, Security (WEP, WPA, etc.), authentication and even network type (Ad Hoc or Infrastructure) information.

What the profiles don't contain, however, is other network-related information such as TCP/IP setting information, Windows domain, SMTP (outgoing mail) server, etc. Mac users can use the built-in Network Switcher capability to handle this chore, but Windows doesn't have an equivalent. However, for $20 Netswitcher will perform these duties for all versions of Windows.
