According to my Wyze camera manual, error code -90 indicates that the camera has lost its ability to communicate with the Wyze cloud service. When the code triggers, you’ll see the following message on your camera’s live feed:
“Device is offline (error code 90). Please check your internet connection or power cycle the camera.”
Code 90 most often appears after you’ve added a new Wyze camera.
It can also pop up when you log into the app for the first time, or after rebooting your router or camera.
In most cases, you can resolve the issue by checking your internet connection and power cycling your camera.
The correct way to fix error code 90 will depend on what’s causing it.
Here are eight ways to fix the problem, starting with the simplest methods.

1. Check Your Internet Connection
If your home’s WiFi isn’t working, your Wyze cameras won’t be able to connect.
This is easy to diagnose when you’re at home.
See if you can pull up a website on your computer or smartphone.
Is your internet working normally? If not, you’ll have to see whether there’s an outage or an issue with your router.
You’ll have to get more creative with your diagnosis if you’re not home.
You can try and access another smart home device.
If multiple devices are down, you probably have an internet outage.
Some internet service providers also have online outage maps.
You can log in and see if there’s a known outage in your neighborhood.
2. Power Cycle Your Wyze Camera
Power cycling is a tried and true method of fixing many electronics.
When you disconnect a device from all power supplies, you reboot its internal components.
This fixes any problems caused by a frozen process.
Here’s how to power cycle a Wyze camera:
- Unplug your camera. You can either unplug the power supply from the wall or the back of your camera.
- Wait for 10 seconds to allow any residual power to drain.
- Plug the camera back in and wait for it to start up.
3. Reset Your Router
If your Wyze camera still doesn’t work, try resetting your router.
To do this, unplug the power supply from the back of your router.
If your modem and router are separate, unplug your modem as well.
Now, wait around 10 seconds.
Plug the modem back in, and wait for all the lights to come on.
Then, plug in the router, and do the same thing.
When all the lights are on, verify that your internet is connected.
Then try viewing your camera again.
With luck, everything will work.
4. Check Your Router Settings
Once, resetting the router didn’t even work, and I had to dig into Wyze’s advanced troubleshooting guide.
As it turns out, some of my router settings were wrong.
Wyze cameras are compatible with 802.11b/g/n, with WPA or WPA2 encryption.
If your router settings have changed or you’ve upgraded your router, you’ll need to fix them.
Every router is different.
I’m giving you a general guide here, but you may need to check your router manual for more information.
If your ISP owns your router, you can call their support line for more help.
That said, here’s a broad overview:
- First, log into the Wyze app, and delete any cameras that aren’t working. Tap the pencil icon on the home page to bring up a list of your devices. Then, tap “Edit Devices” and highlight every camera you want to delete. When you’re finished, tap “Done.”
- Open a browser on your computer, and navigate to your router. You can usually do this by typing “192.168.0.1” in your address bar. For login information, check the label on your router and look inside the router. You may have to call customer support for help with this.
- Follow your manufacturer’s instructions for changing the router settings. Make sure the WiFi mode is set to 802.11 b/g/n and the security option is set to WPA2 or WPA/WPA2.
- Ensure that your router’s 2.4GHz band is broadcasting. If you have a dual-band router, make sure that “band steering” is turned off. This can automatically push the camera to the 5GHz band, even though Wyze cameras only support 2.4GHz WiFi.
- Save your settings and log out of your router.
- Reset your router as you did before.
- Log back into your Wyze app and re-add any cameras you deleted.
5. Examine Your Camera’s Hardware
In some cases, your camera might not connect properly because you’re using incompatible hardware.
Try the following fixes, and see if they help:
- Take out your Micro SD card, then reboot your camera and see if it works. If your card was incompatible, your camera should now stream properly. Keep in mind that this isn’t a long-term solution, since you won’t be able to save your recordings. You’ll need to find an SD card that’s compatible with Wyze cameras. If you replace your card, be sure to download all your Wyze camera recordings locally from your old SD card.
- Make sure you’re using the original power cable and adapter. Third-party components can supply an incorrect amount of current, causing your camera to malfunction.
- If you’re already using the original cable and adapter, try a third-party set. The original equipment may have gotten damaged.
6. Give Your Wyze Camera a Static IP Address
If you’re using more than one Wyze camera, you may have an IP addressing problem.
This happens because the Wyze app tracks your cameras by IP address.
However, any time your router restarts, it assigns a new address to each device.
All of a sudden, the app can’t find your camera, and you get error code 90.
The solution to this problem is to assign each camera a static IP address.
To do this, you’ll need to use a browser and log into your router.
Do this the same way you did when you checked your settings in Method 4.
Once again, it’s impossible to give a precise guide, because all routers are different.
Look in your menu for “DHCP Clients List” or something similar.
This should bring up a table of your connected devices, along with their IP addresses and MAC IDs.
Write down the IP and MAC.
You can also find the MAC ID on the box or the bottom of your camera.
Next, navigate to “DHCP Reservation,” “Address Reservation,” or a similar screen.
You should see an option to add new devices.
Do this, then type in the MAC and IP address for your camera, and select the option to enable static address.
Repeat the process for each camera, then restart your router.
If any cameras still aren’t working, you may have to remove them from the app, then re-link them.
7. Downgrade Your Camera Firmware
Normally, you want to have the latest version of your camera firmware.
However, a brand new firmware update will occasionally come with bugs.
In that case, you’ll have to manually roll back your firmware on each camera.
To do this, you’ll need to download the correct firmware, which will come in a “.bin” file.
Then, you can save that file to a Micro SD card and transfer it to your camera.
Reset your camera, and the firmware will install in just a few minutes.
You can find complete instructions for each camera here, along with firmware links.
8. Factory Reset Your Camera
If all else fails, you can factory reset your camera.
You should only do this as a last resort since you’ll lose all of your settings.
You’ll also have to update your firmware afterward, since you’ll have been rolled back to the original.
To do this:
- On the Wyze Cam and Wyze Cam Pro, press and hold the setup button for 10 seconds.
- On the Wyze Video Doorbell and Wyze Video Doorbell Pro, press the reset button on the back.
- On the Wyze Cam Outdoor, there is no factory reset function.
In Summary
Wyze error code 90 appears when your camera can’t stream video to the Wyze cloud.
The solution depends on the cause of the problem.
It can be as simple as resetting your router, or as complicated as giving your camera a static IP address.
That’s why I recommend working through the solutions in the order I listed them.
Nine times out of ten, the solution is a simple one!
