How do I troubleshoot a TI-Navigator Access Point that's not being detected by the computer?

To troubleshoot a TI-Navigator Access Point that's not being detected by the computer, first verify the items below:

• Verify that the TI-Navigator Access Point is connected to the AC Adapter and plugged into a valid power source.

Please Note: If plugged in correctly and working properly, the TI-Navigator should display a solid [Power] and a blinking [100 Link/Act] [Signal 802.11b/g] lights.

• Verify the USB cable that connects the Access Point to the computer is one you received when you purchased the TI-Navigator system.
• Verify the USB cable that connects the Access Point to the computer is securely connected on both ends. Also, make sure the USB cable is connected to one of the computer's on-board USB ports and not a USB hub.
• Verify the computer's on-board USB port is working properly. To check this, disconnect the Access Point and try connecting a personal USB device (such as a cell phone or thumb drive) to the port being used by the Access Point.
