Solution 26652: Troubleshooting TI-Nspire™ Navigator™ Wireless Cradles and Wireless Network Adapters Not Being Detected by TI-Network Manager.
How do I troubleshoot TI-Nspire Navigator Wireless Network Adapters and Wireless Cradles that are not being detected by TI-Network Manager?
Before attempting to troubleshoot TI-Nspire Navigator Wireless Network Adapters and Wireless Cradles first verify the items below:
• Verify the all handhelds are powered on.
• Verify that the TI-Nspire CX Handhelds or Wireless Cradles have been charged overnight and have at least 25% or above battery charge.
• Verify that the latest version of TI-Nspire family handheld OS (Operating System) and TI-Nspire Navigator Teacher software is installed.
Please Note: To check the version of TI-Nspire Family OS installed and battery charge, with the handheld turned [ON], press [Home] [5] [4]. To check the version of TI-Nspire Family Software, with the software open, click [Help] [About].
Additional Note: If there are multiple TI-Nspire Navigator Systems at your location verify all systems are updated to the latest version. If they are not all updated to the latest version all systems at the location may not work correctly.
• Verify that the Wireless Cradles and Wireless Network Adapters are attached to the TI-Nspire Family handhelds.
• Verify the Wireless Cradles are switched to the [ON] position using the lever located on the back.
• Verify the TI-Nspire Navigator Access Point is setup correctly and has latest version of firmware.
• 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 TI-Nspire Navigator Access Point is in an open elevated position and is not resting on top of another electronic device.
• Verify that all the TI-Nspire Family handhelds are within 60 feet of the Access Point. Any distance beyond 60 feet is outside the Access Point’s range.
• Verify that there are no known devices that cause interference in the environment such as Microwaves, 2.4ghz cordless devices (phones, microphones, etc) and large electronic equipment (such as an HVAC system). If possible, turn them off or place the Access Point in a location situated away from them.
• Verify if other 802.11 wireless Access Points are located at your site. If there is other 802.11 wireless Access Points find the channel they operate on and switch the TI-Nspire Navigator Access Point to a different channel. For assistance verifying this item please contact your Network Administrator for your site.
Please Note: Only use network channels 1, 6 and 11 when setting the Access Point to another channel to avoid channel interference. These channels are the only main channels. All other channels not listed will actually interfere with the main channels, for example channel 3 will overlap network space from both 1 and 6 since it lies in betwen these channels
• Verify there are no Rogue network detecting and/or blocking systems in the environment. To try and remedy this, it would be necessary to add the MAC address, located at the bottom of the Access Point, to the rogue network detecting and/or blocking system. This usually prevents the rogue network detecting and/or blocking systems from interfering with the operation of the Access Point. For assistance verifying this item please contact your Network Administrator for your site.
Once you have verified the items above, please try the troubleshoot steps below to detect the not detected handhelds:
Please Note: If none of the Wireless Cradles and Wireless Network Adapters are detected, you should attempt the troubleshooting steps listed for the TI-Nspire Navigator Access Point in Solution 26650.
First determine which of the Wireless Cradles and Wireless Network Adapters are not being detected by using one of the following methods below:
Method 1:
You can use the wireless icon listed on the TI-Nspire Handheld's display to verify what wireless state the Wireless Cradles or Wireless Network Adapters is in. For assistance using this method please visit Solution 30390.
