VLANs allow you to segment your network into different virtual networks, each with its own security and management policies. This is particularly useful for networks with multiple WiFi SSIDs that require segregation. For instance:

  • Guest Networks: Keep your guests on a separate VLAN to prevent them from accessing your private network.
  • IoT Devices: Isolate your IoT devices on their own VLAN to enhance security and prevent them from interacting with more critical network resources.
  • Work and Home: Create distinct networks for work and personal use, ensuring that sensitive work data remains secure.

The Starlink router offers basic functionality, like splitting the 2.4 GHz and 5 GHz bands, but lacks the advanced capabilities to create and manage VLANs. Third-party routers typically provide these advanced features, offering greater control and security over your network.

Regular Firmware Updates

Premium router brands often provide regular firmware updates to address security vulnerabilities and improve performance. This proactive approach to security can help safeguard your network against the latest threats and ensure that your router remains up-to-date with the latest features.

The StarLink Router: Is It Right For You?

While the Starlink router provides a convenient and straightforward way to get online, it may not meet the needs of all users. Whether you’re looking for enhanced performance, greater customization, improved reliability, or advanced security features, a third-party router can offer significant advantages. By investing in a high-quality router, you can optimize your Starlink setup and enjoy a more powerful, secure, and reliable internet experience.
