How to Fix Wyze Error Code 90 (Device Offline Fix)

By SmartHomeBit Staff •  Updated: 07/18/22 •  8 min read

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.

Here’s how to do it.
 

How to Fix Wyze Error Code 90

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:

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:

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:

 

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:

 

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!
