B
BETTER THAN MOST
The Verdict
This is one of the better routers on the market — and it still has gaps that matter. Out of the box, change the default admin password and disable WAN-side admin access. Without router-level VPN or strict network segmentation, your work laptop, banking sessions, security cameras, and any infected smart device all share the same flat network.
A B grade is a relative ranking in a market where the floor is low. The gaps are real, they just aren’t urgent.
