uppercase and lowercase letters, numbers, and if allowed, special characters such as
Change the password periodically.
Change the default password provided by the manufacturer for administrator access to the
access point or wireless router. Some routers let you change the administrator name as well.
Turn off administrative access over wireless if possible. If you do this, you need to connect to
the router with a wired Ethernet connection when you want to make configuration changes.
Turn off remote administrative access over the Internet on your router, if possible. You can use
Remote Desktop to make an encrypted connection to a computer running behind your router
and make configuration changes from the local computer you are accessing over the Internet.
To avoid accidentally connecting to another party's wireless network, turn off the setting to
automatically connect to non-preferred networks. This is disabled by default in Windows XP.
