Orbi Android App Shows "No Connected Devices Found" Under Network Map

This issue appears to be common right after a firmware update. The ORBI needs a lot of "settling" time to allow all the data from the satellites and router to stabilize. I recently updated to 2.5.1.8 (4 days ago). I have an iPhone 8 and the ORBI iOS app showed a similar situation, i.e., "No connected devices." until after about 24-36 hours. I'd wait patiently for another day or so. Don't do any reboots or resets until the 24-36 hours has passed. If you're still getting a bogus app display, I recommend a factory reset of the satellite.

Good luck!
