Meross Devices Keep Disconnecting from WiFi Network
- Router's DHCP lease time is too short
- Router firmware is buggy or needs an update
- Too many devices on the WiFi network
Problem Description
Multiple Meross smart devices in your home keep randomly disconnecting from your WiFi network. They go offline in the app, become unresponsive to voice commands, and require manual intervention (like a power cycle) to come back online. This happens frequently, sometimes multiple times per day.
Symptoms
- Devices show as Offline in the Meross app
- Alexa or Google reports devices are not responding
- Disconnections happen randomly to different devices
- Power cycling a device brings it back temporarily
- The problem started after getting a new router or ISP
- Other non-Meross smart devices work fine
Recognize these? Here's what usually causes it.
Common Causes
- Router's DHCP lease time is too short
- Router firmware is buggy or needs an update
- Too many devices on the WiFi network
- WiFi signal is weak or has interference
- Access Point Isolation is enabled on the router
- The Meross devices need a firmware update
Most fixes happen in the first 3 steps.
Assigning static IPs outside of the DHCP range can cause conflicts. Ensure your reserved IPs are within the DHCP scope or configure a separate static IP pool on your router.
Tools & Requirements
Step-by-Step Solution
Increase DHCP Lease Time
Login to your router's admin panel. Find the DHCP settings. The DHCP Lease Time determines how often a device must renew its IP address. A short lease time (e.g., 1 hour) can cause devices to drop offline during renewal. Increase the lease time to 24 hours or longer (e.g., 86400 seconds or a week). Save and reboot the router.
Disable Access Point Isolation
Access Point Isolation (also called Client Isolation or AP Isolation) is a router setting that prevents wireless devices from communicating with each other. This can break smart home device discovery and control. In your router's wireless settings, find and disable this option. It may be under advanced wireless settings.
Assign Static/Reserved IP Addresses
Instead of relying on dynamic DHCP, assign a reserved or static IP address to each Meross device. In your router's DHCP settings, find the list of connected devices. For each Meross device, note its MAC address and assign a fixed IP (e.g., 192.168.1.150). This prevents IP conflicts during lease renewals.
Update Router and Meross Firmware
Check your router manufacturer's website for firmware updates. Outdated router firmware is a common cause of WiFi instability. Additionally, open the Meross app and check each device for firmware updates. Apply all available updates. Firmware updates often contain stability improvements for WiFi connectivity.
Improve WiFi Signal and Reduce Congestion
If devices far from the router drop more often, signal strength is an issue. Consider adding a WiFi mesh system or range extender. Also, if you have many smart home devices (30+), your router may be struggling. Some consumer routers have a limit on the number of connected devices. Check your router's specifications and consider an upgrade if needed.
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.
If you recently changed your ISP or router, your new equipment may have different default settings. Always check DHCP lease time, AP isolation, and band steering settings on new routers.
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 firmware is buggy or needs an update
- Too many devices on the WiFi network
- WiFi signal is weak or has interference
- Access Point Isolation is enabled on the router
