Wyze Cam Error Code 90: Device Offline Troubleshooting

Troubleshoot Wyze Cam error code 90 (device offline) in Canada. Fix connectivity issues, check Wi-Fi, and ensure optimal security.

Frequently Asked Questions

•Why does my Wyze Cam keep going offline in cold weather?

Extreme cold can affect the power supply's voltage output. Test voltage under load at -20C.

•How do I check the Wi-Fi signal strength for my Wyze Cam?

Use a Wi-Fi analyzer app on your smartphone and walk near the camera to check the RSSI (Received Signal Strength Indicator).

•What are the best Wi-Fi settings for Wyze Cams on a Bell Giga Hub?

Ensure the 2.4GHz Wi-Fi is enabled and not combined with the 5GHz band. Consider splitting the bands for better compatibility.

Observed Symptoms:

The Wyze Cam displays error code 90 in the Wyze app. The camera's LED indicator is either flashing yellow or solid blue but unresponsive. The device is unreachable via the local network and the cloud.

Possible Causes:

Weak Wi-Fi signal (RSSI below -70dBm) at the camera's location.
2.4GHz Wi-Fi channel congestion, especially in densely populated urban areas.
Router firewall blocking the Wyze Cam's outbound connections.
Incorrect Wi-Fi password or network settings saved in the Wyze Cam configuration.
Power supply issues, insufficient voltage causing instability especially in cold weather (potential voltage drop at -20°C).
Firmware corruption or incompatibility with the current Wyze app version.

Technical Background:

The Wyze Cam relies on a 2.4GHz Wi-Fi connection to communicate with the Wyze cloud servers. Error 90 indicates a failure to establish or maintain this connection. This may be due to a weak signal, incorrect network configuration, or device malfunction. Power consumption is usually ~2W when active, spiking to ~5W during recording.

Safety Warning:

Ensure the Wyze Cam is securely mounted to prevent it from falling and causing injury. Protect your Wi-Fi network with a strong password and enable WPA3 encryption where available. Be aware of potential privacy risks associated with cloud-based security cameras.

Recommended Action:

1

Verify the Wi-Fi signal strength at the camera's location using a Wi-Fi analyzer app on a smartphone. Aim for an RSSI above -60dBm.
2

Power cycle the Wyze Cam by unplugging it for 30 seconds and then plugging it back in. Allow 5 minutes for it to reconnect.
3

Ensure the Wi-Fi password entered in the Wyze app is correct. Double-check for typos or special characters.
4

Check your router's firewall settings to ensure that it is not blocking outbound connections from the Wyze Cam. Specifically, allow connections to Wyze servers.
5

If using a Bell Giga Hub or Rogers Ignite router, ensure the 2.4GHz Wi-Fi is enabled and not combined with the 5GHz band under a single SSID. Consider splitting the bands.
6

Perform a factory reset on the Wyze Cam by pressing and holding the setup button for 10 seconds until the LED flashes yellow. Then, re-add the camera to the Wyze app.
7

Ensure the Wyze Cam's firmware is up to date through the Wyze app. Outdated firmware can cause connectivity issues.

Prevention:

Regularly check the Wi-Fi signal strength at the camera's location.
Periodically power cycle the Wyze Cam to clear its cache and refresh its connection.
Keep the Wyze Cam's firmware up to date through the Wyze app.
Consider assigning a static IP address to the Wyze Cam in your router's settings to prevent IP address conflicts.
Before winter, check the voltage output of the power adapter with a multimeter under load to ensure it's within spec.
