Wireless Networking

This section applies to the Wireless Cable/DSL Gateway only.

Ensure that you have a Wi-fi certified 802.11b 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 Gateway contains an Access Point that is designed to operate in Infrastructure mode. Ad Hoc mode is not supported by the Gateway.

Check the status of the Gateway 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” on page 46 and enable wireless networking.
