We just got the new AR-VR Kit for our school. It comes with a Acer Chrome OS Tablet. I've installed the Google Expeditions app on the Chrome OS Tablet but I cannot get the tablet to communicate with the Pixel 3a's in the kit. We have the standard VR kit as well and what we did with that was use the router that came with the kit to create a LAN with no outside access that all the devices in the kit can use to participate in the expedition. I tried to replicate that scenario with the AR-VR kit. The Google Expeditions Android app is running on the Chrome OS Acer Tablet. I have downloaded the Expedition to the tablet using a different network before attempting to start the expedition. I select the downloaded expedition from my library and start it as a guide while connected to the EXP1 SSID created by the TP link router that comes with the kit that is LAN only. I then launch the Expeditions app on one of the Pixel 3a phones that is also connected to the EXP1 SSID that is LAN only. The issue is that the Pixel 3a phone cannot see my guide Chrome OS Acer Tablet. If I connect both the tablet and the phone to one of our managed WiFi networks, or to my personal phones hot spot, I am able to guide the Expedition with the Chrome OS tablet and the Pixel 3a is able to join the Expedition. Also if I use a Samsung Android tablet instead of the Chrome OS Acer Tablet the whole experience works without issue on the LAN only network. It seems as if the Chrome OS Acer Tablet will only work if it has outside access. Has anyone else experienced anything like this? I really don't want to have to rely on our WiFi infrastructure to run the kit.
