Solution 26650: Troubleshooting a TI-Nspire CX Navigator (TINAVAP3), TI-Nspire Navigator (TINAVAP2), and TI-Navigator (Nav-AP-US) Access Point That's Not Being Detected by a Computer. 

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

To troubleshoot an Access Point (AP) that's not being detected by the computer verify the items below:

• TI-Navigator (Nav-AP-US) Only: Verify that the AP is connected to the AC Adapter and plugged into a valid power source. 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 AP to the computer is securely connected on both ends.
• Try connecting the USB cable 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 AP and try connecting a personal USB device (such as a cell phone or thumb drive) to the port being used by the AP. If the USB port detects the newly connected device, it is working properly.

After verifying the above items, please try the troubleshooting steps below to detect your AP:

• First try removing the power from the AP for about 10 seconds and reconnect the power and wait about 1 minute for the AP to detect using the steps below: 
TI-Navigator (NAV-AP-US): Disconnect the AC Adapter.
TI-Nspire Navigator (TINAVAP2) and TI-Nspire CX Navigator (TINAVAP3): Disconnect the USB cable. 

• TI-Navigator (NAV-AP-US) Only: Press the reset button located on the bottom of the AP for 5 seconds to reset the AP to default settings.

If still not, detected try the additional troubleshooting steps below:

• Update your macOS operating system to the latest version.
• If your macOS computer only has USB-C ports, use a USB-C to Micro-USB cable to connect your AP directly to your computer. If you need to purchase one, you can find them by searching the internet for “USB-C to Micro-USB cable”. Please also verify the cable you purchase supports data-transfer as some cables support charging only.
