General Troubleshooting Steps
If LabQuest Viewer is not able to connect to the LabQuest or shows a blank list* of available LabQuest devices, try these steps:

1. Make sure the LabQuest is powered on and connected to the same network as the iPad. (Depending on how your network is configured, devices on one WiFi network may not be allowed to communicate with devices on another network.)

2. Verify that LabQuest Viewer is enabled.
For LabQuest 3
a. Tap the Settings icon on the top Notification Bar and select the Connections App.
b. Tap the Viewer icon.
c. Make sure the Viewer is set to “On”.

For LabQuest 2
a. Tap the Wi-Fi icon on the LabQuest 2 toolbar.
b. Tap the Viewer gear icon.
c. Make sure the Viewer is set to “On”.

For original LabQuest
a. Tap the Home icon on the toolbar.
b. Tap Control Panel > Viewer Setup.
c. Make sure the Viewer is set to “On”.

3. Use the refresh button to refresh the list.

4. Manually enter the LabQuest IP address into the Viewer app.
a. Locate the LabQuest IP address
LabQuest 3—Select the Connections App from the Settings menu.
LabQuest 2 and Original LabQuest—Tap the Wi-Fi icon on the LabQuest toolbar.
b. On the iPad, tap the LabQuest Viewer gear icon to access the Setup My Lab screen.
c. Under the Manually add section, enter the IP address of the LabQuest, then tap the + icon.
Note: If manually entering the IP address works, your network is probably blocking Bonjour traffic. Contact your IT department.

*LabQuest Viewer uses Bonjour software for network device discovery. Changes to your iPad network settings will reset the Bonjour discovery software. The software can take several minutes to regenerate the list of available devices.
