Why is my Wi-Fi slow? NetDoctor finds out. One tap runs a full check-up of your home network and tells you, in plain language, whether the problem is your Wi-Fi, your router, your internet provider or DNS — and what to do next. DIAGNOSIS, NOT JUST NUMBERS • A health score with the evidence behind it • Clear answers like "Your Wi-Fi is fine. Your DNS is slow." • Confidence level and step-by-step fixes WHAT NETDOCTOR CHECKS • Phone → router latency, jitter and packet loss • Internet latency and stability • DNS speed compared with Cloudflare, Google and Quad9 • Download and upload speed • Sign-in pages, VPN, IPv6 and Low Data Mode WI-FI OR PROVIDER? WE CAN TELL Run the same test on Wi-Fi and on cellular to see where the problem really is. FIND WEAK SPOTS AT HOME Wi-Fi Health Map: test each room and see which ones need help — based on real performance, not just signal bars. SEE EVERY DEVICE ON YOUR NETWORK Router, Apple TV, printers, speakers, smart home and more. New devices are highlighted — without scary "you've been hacked" alarms. LAG UNDER LOAD The bufferbloat test explains "500 Mbps, but my game still lags." HISTORY See when your network got worse: "Health dropped from 94 to 61." PRIVATE BY DESIGN No account. No cloud. No ads. No tracking. Your diagnostics stay on your iPhone. CATCH DROPOUTS THAT COME AND GO — NEW Calls freeze and games lag, but a speed test looks fine?
