Some networks are set up to allow devices to connect out to the internet, but prohibit communication between devices that are on the network. For example, the LabQuest would not be allowed to connect to an iPad, even though the LabQuest and the iPad are both on the same network. Some guest networks are set up this way, as are some school networks.

In order for LabQuest to share data with any other device, it needs to be both:
-On the same network as the other device
-Allowed to talk to the other device

There is a good chance your guest network does not allow talking between devices, so the first thing to try is to use a different network. If data sharing works on one network, but fails on another, it is possible that the latter network blocks device to device communication. There are some options:

1. (Preferred) Work with your school’s IT department to get the permission for the LabQuest 2 or LabQuest 3 to be on the regular (not guest) school network. This is the best option because the school-provided Wi-Fi network is tuned to work in the school and there are good reasons for having a certain level of network security.

2. Use a Wi-Fi router that is not connected to your school network or the internet. A cheap (~$50) router just needs to be connected to power in order to set up a simple network. Turn it on, join the network from both devices, and everything should work. This is what Vernier trainers do when we set up sessions in hotel conference centers or schools where we do not have permission to use the Wi-Fi.

3. LabQuest 2 and LabQuest 3 have the ability to create a pop-up network. This works in a pinch, but is not as reliable as a real Wi-Fi router. To set this up, see the instructions at:
