Ensure that you have an 802.11b or 802.11g wireless adapter for
each wireless computer, and that it is correctly installed and
configured. Verify that each Wireless computer has either Windows
95 or higher or MAC OS 8.5 or higher.

■

Verify that your wireless computers are configured to work in
Infrastructure mode and not Ad Hoc mode. The Router contains an
Access Point that is designed to operate in Infrastructure mode. Ad
Hoc mode is not supported by the Router.

■

If you have a wired and a wireless NIC in the same computer, ensure
that the wired NIC is disabled.

■

Check the status of the Router Wireless LED, it should be lit if wireless
is enabled and will flash when there is wireless activity. If not lit go to

“Wireless Settings”

and enable wireless networking.

■

Ensure that the TCP/IP settings for all devices are correct.

■

Ensure that the Wireless Clients are using the same SSID or Service
Area Name as the Router. The SSID is case-sensitive
