  • Phone → Home Wi-Fi ✅

Avoid combinations such as:

  • PC → Home Wi-Fi
  • Phone → Mobile Data ❌

or

  • PC → Guest Wi-Fi
  • Phone → Main Wi-Fi ❌

4. Allow WO Mic Through the Firewall

Windows Defender Firewall may block network communication.

Allow WO Mic Client on Private networks, then try reconnecting.

5. Disable VPN

VPN software can place your devices on different virtual networks.

Disconnect the VPN and test the connection again.

6. Update WO Mic

Install the latest version of:

  • WO Mic App
  • WO Mic Client
  • WO Mic Driver

Using matching versions helps prevent compatibility issues.

7. Try Another Connection Method
