Smart home devices that connect over Thread should have a much more stable network thanks to Thread 1.4 support in tvOS 26.
Thread is an IP-based wireless protocol that connects primarily smart home devices around the home. The devices create a self-healing mesh network that can be more reliable in the outskirts of your home than Wi-Fi.
The protocol is much improved with Thread 1.4, which was adopted by Apple in tvOS 26. The change was spotted by Matter Alpha by analyzing the Apple TV network details.
