"I’ve downloaded the app for iOS. I’ve never connected it successfully to my m100. The app always says “make sure your devices and smart phone are connected to the same network”Did you reflash the M100 network firmware after the repair? If not do that - see the user manual for instructions (easy).
"do I need to connect the m100 to WiFi? I’ve not been able to figure out how I might do that. Seems others have connected no problem. Do I need a LAN connection to my home network for that to work?"Yes you need a LAN connection - the M100 only has a RJ45-type network interface (ie wired), no built-in wifi support. So you need either a ethernet cable run from your main router to the M100, or a wifi router/extender bridged from your main router then a short ethernet cable to the M100. The former is waay preferable if your house layout allows it.
