"Luma is having trouble connecting to other Luma(s)"
This typically happens when other Luma(s) are too far from the hub or are too far from the primary Luma (aka the Hub) connected to your modem. We suggest moving this Luma closer to your other Luma(s). Each Luma should be within 40 feet of each other. If this Luma is already within 40 feet, try moving it halfway from where it is now to another Luma. Some homes have significant interference from other electronics.
