Security
Why Keep Your Firmware Updated
Router firmware is critical for network security. Updates patch vulnerabilities that could allow remote access to your network, fix Wi-Fi stability issues, improve throughput performance, and add new features. Given that routers are internet-facing devices, keeping firmware current is one of the most important security measures you can take.
