A staggering 89% of home internet users have never updated their router's firmware, according to Linuxsecurity. This widespread neglect leaves entire networks exposed to hundreds of known, critical vulnerabilities, making them easy targets for cybercriminals. During 2020 and 2021, more than 500 router vulnerabilities were identified, with 18% categorized as critical and 53.5% as high-priority, according to securelist.

Hundreds of critical router vulnerabilities are discovered annually, but nearly 90% of users never update their firmware. This disparity creates a critical gap in home network security, where user inaction meets a constant stream of new threats.

Without a significant shift in user behavior or vendor responsibility, home networks will remain a primary, easily exploitable target for cyberattacks, making how to update router firmware for security and performance in 2026 a crucial, often overlooked, task.

The Critical State of Home Router Security

While users often bear the blame for network vulnerabilities, vendor inaction compounds the problem. Securelist data from 2021 reveals 29.9% of critical router vulnerabilities published in that year went unpatched and unreported by manufacturers. Adding to this, Fkie Fraunhofer De found 46 routers received no security updates within the last year. This dual failure means millions of home users face known threats, effectively abandoned by both their own neglect and manufacturer irresponsibility.

Beyond patching vulnerabilities, regular firmware updates also strengthen firewall and VPN features, helping defend against unauthorized access, according to suncomm. These upgrades can introduce new router features such as advanced VPN support, band lock and Celllock options, improved Quality of Service, and additional configuration tools.

Beyond firmware, basic security habits remain neglected. Linuxsecurity reports 52% of users never adjust factory settings, and 72% never change their Wi-Fi password. This apathy is widespread; a Broadband Genie survey, cited by securelist, found 48% of users left all router settings, including control panel and Wi-Fi passwords, at default. A Broadband Genie survey, cited by securelist, found 48% of users left all router settings, including control panel and Wi-Fi passwords, at default, indicating that even automated firmware updates would leave many home networks fundamentally vulnerable due to unaddressed default configurations.
