Verify that you are using the same SSID, Channel, and Security information as the wireless router or access point. Perform the following steps to verify and, if necessary, update the settings:
Right-click the Utility icon in the system tray and select Manage Wireless Networks.
Select the wireless connection.
Right-click and select Properties.
On the Security tab, verify and, if necessary, update the appropriate connection and security information for the wireless network device.
Click OK and a connection will be established.
Windows XP and 2000
Right-click the Utility icon in the system tray and select Open Utility.
On the Wireless Networks tab, pull down the Add menu and select Use Wizard. Browse through the list of available wireless network devices and locate the correct wireless router or access point. If you do not see the correct device, click Refresh to update the list. Double-click the device. If the correct device still does not appear, click Manually connect to an advanced network and enter the appropriate information to create the entry. For more information about setting up connection profiles and security features, right click the USRobotics Ndx Configuration Utility icon and select Help Files.
When the Properties window appears, verify and, if necessary, update the appropriate connection and security information for the wireless network device. Make sure you do not have the checkbox next to This is a computer-to-computer (ad hoc) network selected. When you are finished, click OK.
On the main screen, click Apply and a connection will be established.
Windows XP and 2000: Change the channel used by the wireless router or access point and check for the network on the Wireless Networks tab.
Verify that MAC address filtering is not enabled on your wireless router or access point. If MAC address filtering is enabled, the MAC address of the Wireless Ndx PCI Adapter or PC Card must be included in the filtering table of the wireless router or access point.
Be sure that each Wireless Ndx PC Card or PCI Adapter that you want to connect to the wireless network is set to Infrastructure mode within the Configuration Utility. If your Wireless Ndx PC Cards or PCI Adapters are not set to Infrastructure mode, they will not be able to communicate with an access point or wireless router.
Determine the WLAN MAC address of the desired wireless router or access point. The WLAN MAC address is usually located on a label on the wireless routers and access points. Check the WLAN MAC address and verify that you are connecting to the correct wireless router or access point.
