How to Fix a Wyze Camera That Keeps Going Offline (Error 90)
It's incredibly frustrating when you open the Wyze app to check on your home, only to be met with the message "Device is offline" or Error Code 90. A security camera that isn't connected is no security at all. This guide will walk you through the most common reasons your Wyze Cam keeps going offline and provide clear, easy steps to get it back online and stable.
The issue is almost always related to either Power or Connectivity.
### Step 1: Troubleshoot the Power Supply
An unstable power source can cause your Wyze Cam to reboot or get stuck in a loop, leading to offline errors.
- Check the Connections: Ensure the micro USB cable is plugged securely into the back of the Wyze Cam and that the power adapter is firmly seated in a working wall outlet.
- Inspect the Cable and Adapter: The original Wyze power accessories can sometimes fail. A faulty cable or adapter is a very common culprit for offline issues. Swap them out. Try using a different micro USB cable and a different USB power adapter (like a spare phone charger) that you know works.
- Bypass Extension Cords: If you are using a USB extension cable, try removing it and plugging the camera directly into the power adapter to see if the extension cord is the point of failure.
### Step 2: Address Wi-Fi and Network Connectivity
Error Code 90 is a specific connection error. Your app knows the camera exists but cannot establish a stable data stream with it. This points directly to a Wi-Fi issue.
- Power Cycle Your Camera and Router: The first and most important step.
- Unplug your Wyze Cam from its power source.
- Unplug your Wi-Fi router from power.
- Wait 60 seconds. This is important to allow the components to fully discharge.
- Plug your router back in first. Wait for it to fully restart (usually 2-3 minutes).
- Once your internet is working again, plug your Wyze Cam back in.
- Check Wi-Fi Signal Strength: Is your camera too far from your router? Walls and floors weaken the signal. In the Wyze app, go to the camera's Settings > Device Info and check the Signal Strength. If it has only one or two bars, the signal is weak, and you should consider moving the camera closer to the router or getting a Wi-Fi extender.
- Check the Status Light: The LED light on the back of the camera tells you its status:
- Solid Blue: Everything is working and connected.
- Solid Yellow: The camera is on but has not been connected to a network.
- Flashing Blue/Yellow: The camera is in the process of connecting or has encountered an error. If it's stuck on solid yellow, it has lost its connection settings.
## Step 3: Re-Sync and Re-Setup
If power and Wi-Fi checks don't solve the problem, you may need to force the camera to re-establish its connection with your network and the Wyze servers.
- Re-run the Setup Process: This often resolves stubborn connectivity issues without losing your saved settings.
- With the camera plugged in, press the Setup button on the bottom or back until you hear a beep and the voice prompt "Ready to connect".
- In the Wyze app, go to the Home tab, tap the + sign in the top left, select Add Device, and choose your camera model.
- Follow the on-screen instructions, which will involve entering your Wi-Fi password again and scanning a QR code with the camera.
- Complete Factory Reset: This is the last resort, as it will wipe the camera completely.
- Delete the camera from the Wyze app first.
- With the camera plugged in, press and hold the Setup button for 10-15 seconds until the status light turns red and it reboots.
- Once the light is flashing yellow, it has been fully reset.
- Add the camera in the app as a brand new device.
By systematically checking the power, improving the Wi-Fi connection, and re-syncing the device if necessary, you can solve the dreaded "offline" error and make your Wyze Cam a reliable part of your smart home again.
