How do I setup a multihomed wireless only network (Windows 10 Pro 64-bit v1809), where the secondary network has no internet?
Router (Internet) < Internal WiFi adapter < Laptop > USB WiFi adapter > Access Point > Digital Sign (No internet)
WiFi1 is primary (metric 1) and connected to router.
LAN is (metric 2) and NOT connected.
WiFi2 is (metric 5) and will not stay connected to AP. It will get to identifying and then just disconnect without warning. If WiFi2 is the only or primary connection then it works properly.
WiFi2 connection is to an Access point connected to a digital. The Access point and USB WiFi adapter have static IP. I would expect to get the Home/Work/Public identification selection, which does not happen. No errors appear on screen. I have not checked Windows Logs. Norton Security is the AV and firewall. I do not have file sharing on this laptop on any network connection. This connection worked on previous desktop system using exact same USB WiFi adapter and LAN connection. The client wants mobility and only has one PC, but must maintain connection to the digital sign. I am awaiting the digital sign company call back. USB WiFi adapter is Netgear and I have installed its latest drivers and application. I cannot use the application to control the wireless networks, as it will disconnect the internal adapter in order to connect the Netgear device.
