The Wyze Video Doorbell Pro is a popular smart home security device, but many users encounter frustrating connectivity issues that prevent it from working properly. If your Wyze Doorbell Pro isn't connecting to WiFi, keeps going offline, or displays error codes, this comprehensive guide will help you resolve these problems quickly and get your doorbell back online.
Understanding Common Wyze Doorbell Pro Connection Problems
Wyze Doorbell Pro connectivity issues manifest in several ways. Users frequently report their doorbell becoming unresponsive after working perfectly for days or weeks. The device may display error codes such as IV22-20004, Error 21022, Error -14, or the notorious Error Code 90. These problems often occur regardless of how close the doorbell is to the router, with some users experiencing disconnections even when the chime and doorbell are positioned within feet of the WiFi source
The core issue typically stems from the unique architecture of the Wyze Video Doorbell Pro system. Unlike standard WiFi devices, the doorbell connects to the Wyze Chime Pro via Bluetooth or a similar protocol, and the chime then connects to your WiFi network. This two-step connection creates multiple potential failure points. Additionally, the doorbell requires adequate power delivery between 16-24V AC with at least 10VA, and insufficient voltage can cause persistent connectivity problems even when the WiFi signal appears strong.
Why Your Wyze Doorbell Pro Keeps Disconnecting
Several root causes contribute to connection failures with the Wyze Video Doorbell Pro. **Power supply inadequacy** ranks among the most common culprits. The doorbell requires a transformer delivering 16-24V AC with a minimum of 10VA. Many older homes have transformers rated at only 10VA, which sits at the absolute minimum threshold. Wire age, resistance buildup over long cable runs, and environmental factors like cold weather can reduce effective voltage below operational levels.
WiFi compatibility issues present another significant challenge. The Wyze Doorbell Pro only works with 2.4GHz networks and cannot connect to 5GHz bands. Routers that combine both frequencies into a single SSID may cause connection instability as the system attempts to switch between bands. Additionally, specific router models, particularly some Xfinity configurations, have documented compatibility problems with Wyze devices.
Signal strength and interference also play critical roles. The doorbell must maintain a strong connection to the Chime Pro, which must then maintain a strong connection to your router. Multiple walls, especially those constructed from concrete, brick, or metal, can significantly degrade signal quality. Router channel congestion on the 2.4GHz band, particularly when using channels other than 1, 6, or 11, doubles interference and causes disconnections.
Firmware and software glitches have plagued various versions of Wyze doorbell firmware. Updates sometimes introduce bugs that cause devices to lose connectivity or fail to reconnect after brief network interruptions. The Wyze app cache can become corrupted, preventing proper communication between your phone and the doorbell.
Step-by-Step Guide to Fix Wyze Doorbell Pro Connection Issues
Step 1: Perform a Power Cycle
Begin with the simplest solution by power cycling both your doorbell and chime. For the Wyze Video Doorbell Pro, press and hold the Reset button on the back for 3-5 seconds until you hear the "power off" voice prompt and the status light turns off. Wait 10 seconds, then press and hold again for 3-5 seconds to turn it back on. If your doorbell is hardwired, you can power cycle by switching the breaker off and back on.
For the Wyze Chime Pro, simply unplug it from the power outlet, wait 5-10 seconds, and plug it back in. The chime should flash red then blue, announce "Bluetooth connected," and eventually display a solid blue light with a "Connection completed" announcement.
Step 2: Verify and Update Your App and Firmware
Ensure your Wyze app is current by navigating to the Account tab and tapping About. Compare your version to the latest release on Wyze's Release Notes page. If outdated, visit your device's app store and update immediately. Next, check your doorbell's firmware by going to Account tab > Firmware Update. Install any available updates, as these often contain critical connectivity fixes.
Step 3: Check Your WiFi Network Configuration
Confirm your doorbell is connecting to a 2.4GHz network, not 5GHz. If your router broadcasts a combined network name for both frequencies, consider separating them into distinct SSIDs through your router's admin interface. Set your 2.4GHz network to use only channels 1, 6, or 11, as other channels experience doubled interference. Additionally, ensure your router security is set to WPA2 only, as WPA/WPA2 mixed mode can confuse some Wyze devices.
Step 4: Verify Power Supply Adequacy
Test your transformer voltage at the doorbell mounting location using a multimeter. You should measure between 16-24V AC. If voltage reads below 16V, your transformer may be inadequate or old wiring may be introducing excessive resistance. A 24V transformer is recommended for optimal performance. If you measure significantly lower voltage, consider upgrading to a 24V 20VA+ transformer.
Step 5: Optimize Device Placement
The Wyze Chime Pro should be positioned within 30 feet of your router. The doorbell should be within 30 feet of the Chime Pro. Check signal strength in the Wyze app by navigating to your doorbell's settings > Device Info > Signal Strength. If signal strength shows 2 bars or less, move the Chime Pro to an outlet closer to the doorbell. Consider installing a WiFi range extender or mesh router system if your home's layout prevents optimal placement.
Step 6: Factory Reset Both Devices
If previous steps haven't resolved the issue, perform a complete factory reset. For the Wyze Video Doorbell Pro, press and hold the Reset button on the back for 3-5 seconds until you hear the power-off prompt. For the Wyze Chime Pro, press and hold the reset button on the side for 3-5 seconds until it announces "Reset successfully".
After resetting, delete the doorbell from your Wyze app, then set up both devices as new. During setup, ensure Bluetooth and GPS permissions are enabled on your phone, and that your phone is connected to the same 2.4GHz network you'll use for the doorbell.
Step 7: Clear App Cache and Force Close
On your mobile device, navigate to app settings, find the Wyze app, and clear its cache. This removes potentially corrupted temporary data. After clearing cache, force close the app completely. Reopen the Wyze app and attempt to reconnect to your doorbell.
Step 8: Router Configuration Adjustments
Access your router's web interface and power cycle it by unplugging for at least 10 seconds. Check that your router isn't running out of DHCP addresses—if your router has been online for an extended period without rebooting, it may have exhausted available IP addresses for new device connections. Temporarily disable your router's firewall to test if it's blocking the connection. If disabling the firewall resolves the issue, add Wyze services to your firewall's whitelist before re-enabling it.
Step 9: Advanced Troubleshooting
If standard fixes fail, consider these advanced solutions. Set up an automation in the Wyze app to restart your doorbell daily, particularly if your ISP's router performs automatic resets. This prevents disconnection after router reboots. For persistent issues with battery-powered installations, consider switching to hardwired power if possible, as consistent power delivery eliminates battery-related connection problems.
Verify that your mechanical chime (if installed) is compatible with smart doorbells. Some older chimes can cause power delivery issues. If using a plug-in transformer instead of hardwired installation, ensure it delivers adequate voltage and amperage—the Elk TRG2440 is a commonly recommended model.
Step 10: Submit Logs and Contact Support
If none of these solutions work, submit an app log before contacting Wyze support. In the Wyze app, navigate to your doorbell's Settings > Wyze Support > Submit a Log. Select Doorbell > Connectivity Issues and note your log number. Contact Wyze support with this information, as persistent issues may indicate a hardware defect requiring warranty replacement.
Preventing Future Connection Problems
Maintaining stable connectivity requires ongoing attention to several factors. Regular maintenance includes rebooting your router monthly to clear DHCP tables and prevent IP conflicts. Check for Wyze app and firmware updates at least monthly, as these often contain stability improvements.
Environmental monitoring is equally important. If your doorbell is battery-powered, monitor charge levels and recharge before they drop below 20%. For hardwired installations, periodically test voltage at the doorbell location, especially during extreme weather, as cold temperatures can reduce transformer output.
Network optimization helps prevent future issues. Keep the number of devices on your 2.4GHz network below 25 to prevent channel saturation. Use a WiFi analyzer app to identify the least congested channel (1, 6, or 11) and configure your router accordingly. Consider upgrading to a mesh WiFi system if your home has challenging layouts with multiple floors or thick walls.
Alternative Solutions
For users experiencing chronic connectivity issues, several workarounds can improve reliability. WiFi extender placement specifically for the doorbell can strengthen signal where router repositioning isn't possible. Position the extender roughly halfway between your router and front door, ensuring it has strong connectivity to both.
Automation-based solutions offer hands-off management. Create a Wyze automation that restarts your doorbell at 3:00 AM daily. This preemptive restart prevents accumulated glitches from causing disconnections. The restart completes in under a minute and ensures fresh connections each day.
Alternative chime options may help. The newer Wyze Universal WiFi Chime connects directly to your WiFi network rather than acting as an intermediary between doorbell and router. This eliminates the two-hop connection architecture that causes many Wyze Doorbell Pro issues. However, verify compatibility with your specific doorbell model before purchasing.
Third-party power solutions can resolve transformer-related problems. If replacing your built-in transformer is impractical, a 24V 0.5A plug-in adapter connected directly to doorbell wiring bypasses the old transformer entirely. This solution works particularly well for apartment dwellers or situations where the transformer is inaccessibly located.
