Glad to see this thread. Been having the same issues with my Stadium. MacBook Pro - Tahoe 26.1. Strong internet connection. Both Stadium and MacBook are connected to wifi without issue, just no communication between the 2. Initially it connected, but would drop connection after a few minutes. Now it won't even connect to stadium, despite it showing as available on the app. Would love to forgo the wifi and connect directly with a USB line directly into the unit, however that feature does not appear to be available other than to update firmware.
