Why Does My Wyze Cam v4 Keep Disconnecting From WiFi?
- WiFi signal too weak at camera mounting location
- Router DHCP lease renewing and assigning a new IP to the camera
- 2.4GHz channel congested with too many devices causing interference
Problem Description
Your Wyze Cam v4 repeatedly disconnects from WiFi and shows offline in the Wyze app. The camera may reconnect briefly after a power cycle but drops again within hours or days. Wyze Cam v4 only supports 2.4GHz WiFi and is sensitive to signal strength. Disconnections are caused by weak WiFi signal, router DHCP lease expiry changing the camera IP address, or the camera firmware having a known WiFi stack issue.
Symptoms
- Wyze Cam v4 shows offline repeatedly in the Wyze app
- Camera requires power cycling to reconnect after going offline
- Camera stays connected near router but disconnects in its mounted location
- Disconnections happen at the same time each day or night
- Camera connects after setup then goes offline within 24 hours
- Wyze app shows error 90 or connection failed after disconnect
Recognize these? Here's what usually causes it.
Common Causes
- WiFi signal too weak at camera mounting location
- Router DHCP lease renewing and assigning a new IP to the camera
- 2.4GHz channel congested with too many devices causing interference
- Camera firmware bug causing periodic WiFi stack crash
- Router 2.4GHz channel width set to 40MHz causing Wyze instability
- Power adapter delivering insufficient current causing WiFi drops
Most fixes happen in the first 3 steps.
Do not mount Wyze Cam v4 outdoors without the optional outdoor housing. Wyze Cam v4 is rated for indoor use only and outdoor exposure will damage the camera and void the warranty.
Tools & Requirements
Step-by-Step Solution
Check Signal Strength at Camera Location
Stand at the camera mounting spot and check your phone WiFi signal on the same 2.4GHz network. Wyze Cam v4 needs a signal of minus 65 dBm or better for stable connection. If your phone shows 1 or 2 bars the camera will disconnect regularly. Add a WiFi extender or mesh node within 5 metres of the camera. After improving the signal power cycle the camera and monitor the Wyze app for offline events over 48 hours.
Assign Static IP in Router
Log into your router admin panel and navigate to DHCP Reservations. Find the Wyze Cam v4 by its MAC address listed in the Wyze app under Device Info. Assign a fixed IP address outside the DHCP pool range. DHCP lease renewals briefly interrupt the camera network connection which can cause the Wyze app to show the camera as offline. A static IP prevents this interruption and often resolves cameras that drop offline at regular intervals.
Set 2.4GHz Channel Width to 20MHz
Log into your router admin and navigate to the 2.4GHz wireless settings. Change the channel width from Auto or 40MHz to 20MHz. The 40MHz channel width can cause Wyze cameras to have interference and connectivity issues due to overlapping with adjacent WiFi channels. 20MHz provides a narrower but more stable channel that Wyze Cam v4 handles more reliably in environments with multiple nearby networks.
Update Wyze Cam v4 Firmware
Open the Wyze app and tap the Cam v4 then tap the gear icon then Device Info and check the firmware version. If an update is available install it. Wyze regularly releases firmware updates that address WiFi stability issues. After updating the camera will reboot and reconnect. Monitor the camera for 24 hours after the firmware update before determining whether the disconnection issue has been resolved.
Use Original Wyze Power Adapter
The Wyze Cam v4 requires 5V DC at 1A. Using a low-output USB adapter or a phone charger cube below 1A causes voltage sag when the WiFi radio transmits causing the camera to drop its connection. Use only the USB power cable that came with the camera connected to a quality 5V 1A wall adapter. If the original adapter is lost use a reputable brand adapter with a 1A or higher output rating.
Quick Solutions
Still having issues? This is usually the deeper cause below.
This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.
Enable Wyze cam notifications in the app so you receive an alert immediately when the camera goes offline. This helps you identify the time and frequency of disconnections.
Most WiFi drop-offs happen right after a router reboot or ISP swap — the device reconnects to the network but silently loses its cloud registration.

- Router DHCP lease renewing and assigning a new IP
- 2.4GHz channel congested with too many devices causing interference
- Camera firmware bug causing periodic WiFi stack crash
