T100: Radio Troubleshooting

Clients have reported seeing issues with the Radio for the T100 tablet connecting to a RTS unit after shutting down the tablet or putting the tablet in airplane mode. Typically the RTS icon will disappear in FieldLink which is the sign that you having radio issues. If you are having any issues with the external radio on the T100 tablet try the following steps to resolve the issue.

Windows Updates

  1. Run all Windows updates prior to connecting the radio module and installing FieldLink.
  2. Do Not Update the tablet to Windows 11

Airplane Mode

Make sure the tablet is not in airplane mode. If it’s in airplane mode turn it off and restart the tablet twice.

Sleep Mode

As a best practice we recommend completely shutting down the tablet every day after you have finished using it for the day. You need to completely exit from FieldLink and then shut the tablet down using the Windows shut down process. We have found in testing that if the tablet just goes to sleep or your put it to sleep that the radio will no longer appear connected in FieldLink. If this happens restart your tablet to see the radio again.
