■ Troubleshooting

If you cannot connect from another device:

• Firewall Note: Your firewall may display a message requesting permission to access the network. You will need to allow access when connecting from another PC or smartphone.

• Wired vs. Wireless: If a user can't connect from their phone even with the setting on, it's usually because the devices aren't on the same subnet (e.g., one is on 5G/LTE and the other is on Wi-Fi).
