My Canon TR4500 is connected via Wi-Fi but still not responding. What specific network settings should I check?

For Wi-Fi connectivity issues, first confirm the printer's network status on its LCD screen; it should show a connected status or an IP address. Try restarting your Wi-Fi router, then restart the printer. Ensure your computer's firewall isn't blocking communication with the printer; temporarily disabling it for testing can help diagnose this. You might also need to re-add the printer to your computer's printer list or reconnect the printer to your Wi-Fi network through its own setup menu, ensuring you select the correct SSID and enter the correct password.
