What This Problem Means

Safe Checks You Can Try

1. Check Wi-Fi signal strength

2. Restart the device and router

Press and hold the setup/reset button on the camera for about 5 seconds until you hear a prompt tone, then release. Wait 60 seconds for it to restart fully. Restart your router by unplugging it for 30 seconds too. Restart your router by unplugging it for 30 seconds. Many disconnection issues resolve with a clean restart of both.

3. Separate the Wi-Fi bands

Some routers merge 2.4GHz and 5GHz under one network name. If the camera switches between bands it can disconnect temporarily. Separate the bands in your router settings and connect the camera specifically to 2.4GHz.

4. Check for Wi-Fi interference

Interference from neighbouring networks, cordless phones or microwave ovens can cause disconnections. In your router settings, try switching to a less congested Wi-Fi channel.

5. Update firmware

Check for a firmware update in Device Settings. Out-of-date firmware can cause connectivity instability.

6. Check battery level

A low battery (charge via USB-C) can cause intermittent disconnections. Check and recharge before monitoring for improvement.
