# Wireless Signal Troubleshooting

If a sensor disconnects frequently, it’s likely due to poor signal strength between the sensor and the hub device. To confirm signal strength go to the sensor in your alarm site and hover over the blue signal bars.

**Minimum Recommended Strength:** Wireless signal strength is measured in RSSI. The sensor RSSI must be -85dBm or higher for a reliable connection. This ensures that there is room for error as the environment can change. Changes include doors opening and closing, windows, boxes blocking paths, people, walls, etc.\

If the signal strength falls below -85dBm. Consider adding additional hubs and/or repeaters. Additionally, ensure that the sensors are in line of sight of any hubs and not in closed-off areas with poor coverage. Lastly, ensure you install the sensors not on metal, which can degrade signal performance.

When testing wireless signal strength, ensure the sensor and hub are mounted in their final position and close any other doors or fixtures around the environment.

This will ensure a more accurate representation of signal strength. If the signal strength still does not exceed -85dBm, install a WH32 as a repeater to boost the signal from the hub or an additional hub.
