Using a Router Without Firmware Updates Poses Security Risks
Key points
- Routers function without firmware updates but lose security fixes.
- Unpatched routers are vulnerable to new security flaws.
- Attackers can use vulnerable routers for malicious traffic or botnets.
- Consider replacing routers after five years or when updates cease.
The Risk of Outdated Routers
A router will continue to connect devices to the internet even after the manufacturer stops releasing firmware updates. However, without these updates, the router loses its ability to fix newly discovered security vulnerabilities. This means that while the hardware remains functional, its security posture degrades over time.
Potential for Exploitation
An outdated router is not automatically compromised, but it remains vulnerable. Attackers frequently target such routers in bulk, using them to relay malicious traffic or to incorporate them into larger networks of compromised devices without the owner's knowledge. Disabling remote administration can mitigate some exposure, but the risk increases over time.
When to Consider Replacement
A five-year mark is a general checkpoint to assess if a router model still receives security updates. Manufacturers like Netgear suggest a four- to five-year timeline for support. If support is ending, users should install the latest available update and plan for a replacement. For those concerned about immediate security, purchasing a new router is an option.
Alternative Firmware Options
For some routers, custom firmware projects like OpenWrt can provide an alternative once manufacturer updates cease. Users need to check their specific hardware revision against OpenWrt's supported device list to determine compatibility. This can extend the life of a router while maintaining security.

Routers continue to function without firmware updates, but they become vulnerable to newly discovered security flaws. While not immediately compromised, these routers can be targeted by attackers to relay malicious traffic or join botnets.
