Connection problems with the eufyCam S3 Pro usually appear during setup, or after a change to your router or Wi-Fi password.
What This Problem Means
If your eufyCam S3 Pro is showing this fault, working through the checks below in order resolves it in the large majority of cases. Each step is safe to try yourself and follows eufy’s official guidance.

- Setup fails part-way
- Won’t pair in the app

Safe Checks You Can Try
1. Use 2.4GHz Wi-Fi
eufy cameras and HomeBase connect on 2.4GHz only. If your router uses one name for both bands, separate them or connect to 2.4GHz during setup.
2. Check the password
Wi-Fi passwords are case-sensitive — re-enter carefully.
3. Press SYNC to pair
During setup, press the camera’s SYNC button for at least 2 seconds until you hear a beep. If there’s no beep and the LED is off, charge the battery first.
4. Reboot your router
Unplug it for 30 seconds and let it fully restart before trying again.
5. Stay close during setup
Keep the device near the router and HomeBase while pairing, then move it to its spot once connected.
6. Enable DHCP
If pairing the HomeBase, make sure DHCP is enabled on your router and temporarily disable any strict firewall rules.
