If You Connected The Hardware First; If You Do Not Want To Use The Setup Wizard - Microsoft MN-500 User Manual

To connect a wireless device to the base station, refer to the
documentation for your device. You will need to configure the
device to use your existing network's wireless network name,
channel, and WEP security key if set.

If You Connected the Hardware First

If you connected the base station before installing the software,
the Setup Wizard may not be able to access the Internet to copy
configuration settings. It is recommended that you disconnect the
base station, reconnect your modem and computer in their original
configuration, ensure that your Internet connection is working, and
then rerun the Setup Wizard.

If You Do Not Want to Use the Setup Wizard

If you do not want to use the Setup Wizard to set up your base
station, you can enter your Internet settings and configure the base
station in the Base Station Management Tool. For more
information, see Chapter 6.
