F
HIGH RISK
The Verdict

This router has documented security problems. Every device on this network — your work laptop, banking app, Ring camera, smart lock — is running at higher risk than it should be.

An F is not a warning — it’s a finding that the router has been independently flagged for security or supply-chain concerns serious enough to warrant action.

  • When the next critical Wi-Fi flaw drops, this router will stay exposed for weeks while newer models are patched

    Patches arrive late, if at all. When the next critical Wi-Fi flaw drops, this router will still be exposed weeks after newer models are protected — and every device on your network rides through it during that window.

    Show technical detail

    Security updates are infrequent. Flaws take a long time to get fixed.: TP-Link has shifted focus to newer hardware. This model receives infrequent security updates.

  • TP-Link is legally required to share your network data with the Chinese government if asked

    The manufacturer is legally required to share your network data with the Chinese government if asked. This isn't theoretical — it's a legal obligation that can't be refused.

    Show technical detail

    The company behind this router is legally required to cooperate with Chinese intelligence: Same exposure as all TP-Link products.

Everything on this network shares the exposure
💻 Work laptop & remote access 🏦 Online banking & passwords 📷 Security cameras & smart locks 👧 Kids' devices & school logins 📱 Every phone & tablet at home 🔊 Smart speakers & streaming
