• Make sure the computer’s wireless card is set to the correct wireless profile. A
wireless profile is a set of network settings unique to a given network. A single
wireless card might have several wireless profiles (for example, one for a home
network and one for an office network). Open the Configuration utility for the
network card installed on your computer, and ensure that the profile selected is the
profile for the device’s network.
• Make sure the device’s network settings match those of your network. Do one of
the following to find the settings for your network:
◦ Infrastructure communication: Open the wireless access point’s (WAP)
Configuration utility.
◦ Ad hoc communication: Open the Configuration utility for the network card
installed in your computer.
• Compare the network’s settings to those on the device’s wireless configuration

4. Use the Wireless Setup wizard on the Wireless Setup tab to change the device’s
settings to match the settings of the network.

from the device.
6. Uninstall the device software completely, and then reinstall the software.
Add hardware addresses to a wireless access point (WAP)
MAC filtering is a security feature in which a wireless access point (WAP) is configured
