Meross Smart Plug Not Connecting to WiFi or Responding

Problem Description

Your Meross Smart Wi-Fi Plug Mini is not connecting to your WiFi network during setup, showing offline in the Meross app, or not responding to commands from Alexa, Google Home, or HomeKit.

Common Causes

  • Smart plug requires 2.4GHz WiFi (5GHz not supported)
  • Router security settings blocking connection
  • Meross cloud service issues
  • WiFi password entered incorrectly
  • Too many devices on the network
  • Firmware needs updating

Solutions

1. Verify 2.4GHz WiFi Network

  • Meross plugs only work with 2.4GHz networks
  • If your router broadcasts both bands with the same name, temporarily disable 5GHz
  • Or create a separate 2.4GHz network with a different name
  • Network password should not contain special characters like quotes or backslashes

2. Reset and Reconnect the Plug

  1. Press and hold the button on the plug for 5 seconds
  2. The LED will flash rapidly (setup mode)
  3. Open the Meross app and tap + to add device
  4. Select your plug model and follow the setup wizard
  5. Keep your phone close to the plug during setup

3. Check Router Settings

  • Disable AP Isolation/Client Isolation if enabled
  • Ensure MAC filtering is off or the plug MAC is whitelisted
  • Check that DHCP has available IP addresses
  • Try temporarily disabling firewall to test

4. Power Cycle Your Network

  1. Unplug your router and modem
  2. Wait 60 seconds
  3. Plug the modem back in first
  4. Wait for modem lights to stabilize, then plug in router
  5. Try connecting the plug again

5. Update the Meross App

  • Update to the latest version from App Store or Google Play
  • Sign out and sign back into your Meross account
  • Check for plug firmware updates in device settings

6. Re-link Voice Assistants

If the plug works in Meross app but not with Alexa/Google:

  1. Open Alexa or Google Home app
  2. Go to linked services and unlink Meross
  3. Re-link Meross and sign in again
  4. Discover devices to refresh the connection

7. Factory Reset

  1. Press and hold the button for 10+ seconds
  2. LED will flash quickly then turn off briefly
  3. Release when LED starts flashing again
  4. Remove from Meross app and set up fresh

When to Contact Support

Contact Meross Support if the LED will not flash during reset, the plug gets excessively hot, or setup fails repeatedly with different networks.
