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.
