    • Remembering Wi-Fi Connection Credentials – The 1-hour and 1-day settings for how long credentials are remembered (WPA Wi-Fi networks) is not working as expected. When LabQuest is connected to the network beyond the specified time-out period, the connection will persist. Disconnecting after the timeout period will require the user to reenter valid credentials as expected. To disconnect from the network and ensure the credentials are removed, do the following: Tap Home, then tap Connections, and then tap Network. Tap the Wi-Fi Radio Enabled check box to disable your Wi-Fi connection.
    • Manual Column Data Loss – Manual column data with decimal precision higher then the column display precision will lose the higher decimal precision when the file is saved or exported. For example, if you enter the number 0.01534 and have the Column Options Display Precision set to the default two decimal places, the table will show 0.02. When the file is saved, the value will be truncated (not rounded) to 0.01, matching the display precision of the column. The data is not recoverable and must be reentered. To retain all desired decimal values, set the column display precision to match the desired precision you want to retain.
    • Connecting to Networks with a Hidden SSID – After a system reboot, networks with a hidden SSID are not automatically reconnected. It will be necessary to manually reconnect to the network.
