Please read before upgrade:

• Upgrading firmware (in most cases) will reset all the settings to default which means you will lose all your settings (including your password).
• You do not have to upgrade Incrementally. You can upgrade the newest version.
• You cannot use the backup settings feature and apply it to the newer firmware.
• Do NOT upgrade firmware from a computer with a wireless connection. Use a computer that you can connect to the router using an ethernet cable. You may damage the router due to the increased packet loss with a wireless connection.
• If your DI-604 was purchased in Europe, this upgrade will not work.
