• Fiber plans deliver equal upload/download and hold up best during peak hours
• Cable, DSL, and mobile broadband typically advertise download speed but lag on upload and during evening congestion
• Reality check: expect 80–95% of your plan speed on a wired test; if you're consistently lower, it's a real issue worth reporting
