End of Support for Wi-Fi 5 and Early Wi-Fi 6: Security Risks You Can’t Ignore

Are you still using an old Wi-Fi router simply because “it still works”? You might want to reconsider.

As new Wi-Fi standards emerge, manufacturers are gradually ending support for older generations—and this trend is now reaching even Wi-Fi 6 routers.

Wi-Fi 5 and Early Wi-Fi 6 Models Losing Support

The landscape of Wi-Fi router support has changed dramatically in recent years. While manufacturers once maintained products for extended periods, the industry has settled on a standard of “approximately 5 years after discontinuation of sales.” This means most Wi-Fi 5 (IEEE 802.11ac) products purchased before 2018 have likely already reached end-of-support status.

However, this timeline is now shrinking even further. Some manufacturers are accelerating their support cycles:

NEC Platforms announced that starting December 1, 2025, their Aterm series support period will be shortened from approximately 5 years to just 3 years after sales discontinuation
Elecom’s WRC-X3000GS ended support in August 2025
Buffalo’s high-end WXR-5950AX12 is scheduled to lose support in January 2026

This means the assumption that “Wi-Fi 6 routers are still safe” no longer holds true. It’s become increasingly important to check your router’s model number on the manufacturer’s website to verify how long support will continue.

Understanding Wi-Fi Generations: What’s the Difference?

Wi-Fi 7 represents a dramatic leap forward compared to Wi-Fi 5 and 6. The headline feature is MLO (Multi-Link Operation), a groundbreaking technology that allows simultaneous communication across multiple frequency bands (2.4GHz, 5GHz, and 6GHz).

This innovation delivers:

Communication speeds approximately 4.8 times faster than Wi-Fi 6
Dramatically improved connection stability
Significantly reduced latency for real-time applications like online gaming, VR, and AR

As Wi-Fi 7 gains traction, the industry is accelerating the phase-out of both Wi-Fi 5 and early Wi-Fi 6 models.

The Hidden Dangers of Unsupported Routers

As of 2025, we’re in a transition period toward Wi-Fi 7, and a 3-year replacement cycle is becoming the new standard for Wi-Fi routers. Continuing to use routers beyond their support period exposes you to serious risks:

Security Vulnerabilities Left Unpatched

The most critical danger is that security flaws discovered after support ends will never be fixed. When manufacturers stop providing firmware updates, your router becomes an attractive target for attackers.

Compromised routers can be turned into “bots”—remotely controlled devices that, without your knowledge, can be used in cybercrimes such as DDoS (Distributed Denial of Service) attacks against businesses and critical infrastructure.

Performance and Compatibility Issues

When firmware updates stop, your router won’t receive improvements for compatibility with newer devices or performance optimizations. This can result in slower speeds or unstable connections when you introduce new smartphones, computers, or other devices to your network.

A New Standard for Router Replacement

Wi-Fi routers are no longer just internet connection devices—they’re the critical gatekeepers of your home network security. Using an unsupported router is comparable to leaving your front door unlocked when you leave the house.

The new best practice: Check your router’s support status every 3 years from purchase date, and plan to upgrade to the latest Wi-Fi 6 or Wi-Fi 7 models when necessary. This proactive approach is becoming essential for maintaining both a fast and secure internet environment in your home.
