Bosch EasyControl frequently loses Wi‑Fi connection, causing the app to show the thermostat as offline.

Safety first: No electrical risk; network-only changes.

• 1. Improve signal: Move the Wi‑Fi router closer to the EasyControl or add a Wi‑Fi extender/mesh node nearby.
• 2. Change channel: In router settings, select a less congested 2.4 GHz channel (1, 6, or 11) based on a Wi‑Fi analyzer app.
• 3. Disable aggressive power saving: Turn off features like "Wi‑Fi eco" or client isolation that may disconnect idle devices.
• 4. Assign static DHCP lease: Reserve a fixed IP address for the EasyControl to reduce reconnection issues.

Professional help: If other devices are stable on Wi‑Fi but EasyControl alone drops frequently, its Wi‑Fi hardware may be failing and the unit may need replacement.
