This information pertains to the original LabQuest.

If you have LabQuest 2, see this article.

Once a Vernier Wi-Fi USB Adapter (WIFI-USB, discontinued) is added, the original LabQuest supports two functions via Wi-Fi:
1. Wi-Fi based printing.
2. Connection to LabQuest Viewer® (LQ-VIEW).

Original LabQuest does not support data sharing, Graphical Analysis for iPad, Vernier Data Share, or other functions that were introduced as part of the Connected Science System. When connected to a computer, the original LabQuest is compatible with the Data Sharing feature of Logger Pro 3. For more, see:
