MODERATE RISK
The Verdict

This router gets the basics right, but the gaps are significant. Does not support Wi-Fi 6 or WPA3. If any device on your Wi-Fi gets infected — a kid’s tablet, a smart bulb, a guest’s phone — it can reach your work laptop and banking app on the same flat network.

A C grade is not a sign-off. It means there are real, exploitable issues affecting this network every day.

  • Your Wi-Fi password can be captured by anyone within range of your home

    Wi-Fi 5 uses WPA2 encryption, which has a known weakness (KRACK) that can let attackers near your home capture your Wi-Fi password. WPA3 fixes this and is supported on newer routers.

    Show technical detail

    Wi-Fi 5 - aging hardware: Does not support Wi-Fi 6 or WPA3. WPA2 is functional but less secure than current standards.

  • Login credentials passing through this router can be captured

    Login credentials — including router admin, Wi-Fi, and anything passed through an unencrypted connection — are at risk.

    Show technical detail

    Default credentials widely known: Default Wi-Fi and admin passwords are printed on the device and available online. Many customers never change them.

  • Spectrum can change settings on your router without telling you

    Your ISP can access this router remotely to push updates and diagnose issues. This is normal for ISP-owned equipment, but it means there’s another party with admin access to your home network.
