Wyze Error Code 90 (Solved) - Fix in Seconds!

Quick Fix

The Wyze camera error code 90 indicates a loss of internet connectivity for your Wyze camera. To resolve this, power cycle the camera by switching it off, disconnecting it from the power source, waiting for 20-30 seconds, and then turning it back on.

Wyze Cam is one of the most popular smart home cameras on the market. It can be quickly linked to a mobile phone, allowing you to keep tabs on your home even when you’re not there.

Recently, I could not stream one of my Wyze cams on my phone, and it was showing the camera as the Wyze device was offline (error code 90).

What Does Wyze Error Code 90 Mean?

Error code 90 means that your Wyze camera is unable to communicate with the Wyze streaming servers.

How to Fix Wyze Error Code 90?

How to Fix Wyze Error Code 90?

As I have mentioned earlier, the error code 90 occurs in Wyze cameras when the cameras have issues accessing the Internet or communicating with Wyze streaming servers.

There are multiple ways to fix the issue, but there are a few checks that you have to do before fixing the error.

  • Make sure that your phone and Wyze cameras are connected to the internet.
  • You must ensure your router’s Firewall is not blocking Wyze’s connection. (If you don’t know how to disable the Firewall, we have written it below.)
  • Ensure you use the correct USB cable that is 100% functional and correctly plugged inside the camera.
  • Ensure that your Internet is working fine and you have enough remaining bandwidth.

You must also understand how the LED indicator works on Wyze Cameras, as it will help you troubleshoot the error.

  • Solid Red: Your camera is powered and initializing.
  • Flashing Red: Your camera is ready to connect.
  • Flashing Red + Blue: Your camera is connected and finishing the setup.
  • Solid Blue: Your camera works properly and can be accessed from the mobile app.

With all that in mind, let’s get to fixing the error and discuss more about how to get the Wyze camera back online.

Expertise Required

1. Power Cycle Your Wyze Camera

The quickest way to eliminate this error is by power cycling your cam if you don’t feel like going through a ton of debugging.

To restart wired cameras, follow these steps:

To restart a Wired Wyze Camera just Unplug cable

Step 1: Unplug the power cable of the camera.

Step 2: Plug it back in after 30 seconds.

Step 3: Once the camera is plugged in, wait for the LED light to turn solid blue to be properly functional.

The process is identical for restarting wireless Wyze cameras; follow these steps:

To restart a Wireless Wyze Camera, just press the power button

Step 1: Turn off the camera using the power button.

Step 2: Turn it back on after 30 seconds.

Step 3: Again, wait for the LED indicator to be solid blue.

If the LED indicator is solid blue, the error code 90 should have been fixed. If not, try the other fixes listed below.

2. Temporarily Disable Network Firewall

A firewall can block the Wyze cameras from being connected to your Internet.

You need to disable the Firewall in your router temporarily. The process of doing it is similar in most routers, but the labels are different.

You can google the process for your router model.

I have been using Xfinity Router, so to disable the Firewall on xFi routers, follow these steps:

How to Disable your firewall on Xfinity Internet?

Step 1: Ensure that your PC is connected to the router.

Step 2: Open your browser, type in the address bar, and press Enter.

Step 3: Type your username and password. (Default username and password are “admin” and “password,” respectively.)

Step 4: Go to Firewall from the menu on your left side.

Step 5: Select Custom Settings.

Step 6: Select Disable Entire Firewall.

That is it. Your Firewall will be disabled until you turn it back on.

3. Switch to the 2.4 GHz WiFi Band

Use 2.4 GHz Band Wi-Fi

Most advanced routers offer dual-band connections, which are 2.4GHz band and 5GHz band.

  • 2.4 GHz Band: The 2.4 GHz band’s longer transmission waves allow it to transmit through walls and other solid things, but it doesn’t provide a fast wireless connection.
  • 5 GHz Band: The 5 GHz band provides a high-speed connection, but the signals are not strong enough to transmit through solid concrete walls.

Unfortunately, the Wyze cameras only work with the 2.4 GHz band, so you must enable it from your router, or else your cameras will never connect to your wireless connection.

4. Re-setup the Camera after Deleting from the App

You can also try deleting the camera from the mobile application and setting it up again, as this solution has worked for many users in fixing Wyze camera code 90.

Follow these steps to delete your camera from the Wyze app:

Delete device from wyze cam app

Step 1: Open up the Wyze application.

Step 2: Select the camera you want to delete.

Step 3: Tap on the Settings gear icon in the top-right corner of the app.

Step 4: Scroll down to the Device Settings and select Delete device.

Step 5: Once you do that, the LED indicator on the camera will start flashing yellow, which shows that the device is no longer connected to the Internet.

Now, you have to add the camera back again in the app. To do that, follow these steps:

Press the reset button located underneath the Wyze cam.

Step 1: Press the reset button located underneath the Wyze cam for at least 10-15 seconds or until you hear “Ready to connect.”

Step 2: Once the camera is ready to connect, go to the Wyze mobile application.

Step 3: Tap on the + icon on the top left corner of the screen.

Step 4: Go to New Device and select Wyze cam.

Step 5: Enter the WiFi name and password manually or scan the QR code that pops up in the application from your Wyze cam.

Step 6: Set the name for the cam, and you will be done!

Hopefully, this will resolve the Wyze cam v3 code 90.

5. Reinstall the Wyze App

Reinstall the Wyze mobile Application

If you’re still having problems after deleting and re-adding the camera to the mobile app, try reinstalling the mobile app.

Step 1: Uninstall the mobile app.

Step 2: Go to PlayStore or App Store.

Step 3: Search for the Wyze app and install it again.

Step 4: Log in to your Wyze account.

That’s it! All of your cams will already be there after logging in.

6. Update Wyze Cam Firmware

Update your Wyze Cam Firmware

We saved the most difficult one for the last.

Up to this point, we’ve tried everything we could to fix Wyze error code 90 without updating the camera’s firmware using an SD card. This is a more technical process, so we’ll save it for last.


Factory reset will erase all settings, restoring the camera to default. Back up your data beforehand to prevent loss.

Wyze regularly releases new firmware updates for its cameras, which improve performance and fix bugs.

While new firmware updates may sometimes introduce new bugs and issues, Wyze typically fixes them quickly.

Doing these checks before flashing your SD card with the latest firmware would be best.

Step 1: Ensure your SD card is no more than 16 GB.

Step 2: Format your SD card via the Wyze mobile application while it is still inside the camera, and ensure that you use FAT / FAT32 format only. (This is very important.)

Step 3: After formatting, turn off the camera or unplug the power source and eject the SD card.

Once you do that, you are ready to download the firmware.

Step 1: Download the latest firmware for your Wyze cam model. You can find all of the released firmware here.

Step 2: Get an SD card adapter, put the SD card inside, and connect it to your computer.

Step 3: Ensure the downloaded file is named demo.bin; if not, rename it to “demo.bin” (very important.)

Step 4: Put the demo.bin file into your SD Card root.

Step 5: Eject the SD card from the PC, and while the camera is powered off or unplugged, put the SD card inside it.

Step 6: Power your Wyze cam or plug the power source back in.

Step 7: Press and hold the reset button until you hear “Ready to connect.” (This can take from 10 seconds to 60 seconds.)

Step 8: Wait for the LED indicator to start flashing a yellow light.

Step 9: Once it starts flashing yellow, set up the camera via the Wyze mobile application again.

If you have successfully done that, congratulations! You are a Genius!

If you still get Wyze Error 90 after the update, then Factory reset is the last option.

7. Reset Your Wyze Cameras to Factory Defaults

Hard resetting your Wyze cam is similar to what we did in deleting and re-adding the cam to the Wyze mobile app.

Step 1: Remove the camera from the mobile application (as discussed above under point no. 4).

Step 2: Eject the SD card from the cam and hold the reset button for 10-15 seconds or until the LED indicator starts flashing a yellow light.

Step 3: Once the yellow light starts flashing, unplug the power source and wait for 15 seconds.

Step 4: After 15 seconds, plug it back in.

Step 5: Put the SD card back inside the camera.

Step 6: Add the camera again in the Wyze application.

Congratulations, your Wyze cam is now factory reset.
