Hi @password23,
Another thing to try to verify that the problem is the network connection over your router, is to connect over the Mobile Hotspot network.
Just follow the steps below:
– On your Windows 10 primary machine, open the Windows Settings -> Network & Internet -> Mobile Hotspot, then switch it ON, select Share my internet connection from “WiFi”
Take note of the Network name and password which you will connect from your Chromebook.
– On your Chromebook, connect your WiFi to the Hotspot network name created by your Windows 10 primary machine.
– Once the chromebook is connected to the hotspot network, check the spacedesk viewer if you can discover now the primary machine and try to connect.
