Is it a wireless signal strength issue? Move one of the Node2's into closer proximity to the wireless access point/router and see if the behavior changes. If so, you might be able to get a wireless access point, or wireless router, with great range. Or you could look into a mesh network link the Linksys Velop.
However, before investing much time, or any money, move one or both of the nodes to see if it's just a matter of wireless signal strength.
