Network Doctor Support

Connect to the Wi-Fi or cellular network you want to test, turn on any VPN involved in the problem, and run Quick Check. Keep the app open while the measurements finish.

Change only one thing before repeating a check—for example, disable the VPN, move closer to the router, or switch from Wi-Fi to cellular. Comparing one controlled change makes the evidence easier to interpret.

Top speed is only one part of the experience. High loaded latency means requests can become delayed while the connection is busy, which can affect calls, games, remote work, and interactive websites.

Custom targets let you check public HTTPS sites and services you rely on. Network Doctor validates reachability and response timing; it does not sign in, bypass access controls, scan local devices, or test private credentials.

Network Doctor 1.1.0 includes every feature in the app. It has no subscription, in-app purchase, restore-purchase step, or upgrade screen.

If you use an earlier version and see a Pro purchase prompt or “Product unavailable,” update Network Doctor from the App Store. Lifetime purchases made in an earlier version remain associated with the Apple Account that made the purchase, but no restoration step is required after updating.

Open Settings and choose Delete all history. This removes locally saved diagnostic reports from the app. Custom targets and app preferences are managed separately.

Include the app version, iOS version, connection type, whether a VPN was active, the action you took, and the exact error message. Do not include passwords, private keys, or unredacted network reports. Remove public IP addresses, private hostnames, notes, and company information before attaching evidence.
