Единственное, трасерт/мтр показывает только первые 4 хопа, последний не совпадает со значением конечного пункта:( **Developer response:** Спасибо! Тот самый обрыв трассировки на промежуточных хопах исправлен в 1.4.2, а в 1.4.3 трейс и MTR стали ещё стабильнее. Обновитесь и попробуйте снова — должно показывать полный путь до конечной точки. ### 4/5 — Лучше, но еще не хорошо *2026-06-05* После обновления пинг заработал, но трейс показывает два пустых хопа и вылетает. Тестирование скорости также не работает. Остальные инструменты вроде работают **Developer response:** Спасибо за подробный отчёт — он помог найти причину (сбой при записи в сетевой сокет на некоторых сетях). Исправление уже отправлено в обновлении 1.4.1. Будем благодарны, если попробуете снова и обновите оценку. ### 3/5 — Сырой продукт *2026-05-25* Работает наполовину. Запускаешь пинг- два пинга проходит, на третий приложение закрывается. Запускаешь трейс- приложение закрывается. Тест скорости так результатов и не выдал. Просто тыкаешь по меню- через несколько открытий/закрытий разделов программа зависает. И.т.д. **Developer response:** Спасибо за подробный отчёт — он помог найти причину (сбой при записи в сетевой сокет на некоторых сетях). Исправление уже отправлено в обновлении 1.4.1. Будем благодарны, если попробуете снова и обновите оценку. ## Frequently asked questions about NetDiag+ Network Toolkit ### What is NetDiag+?

A 30-second probe pings the gateway and the internet at the same time, grades your line A+ to F, and gives you a plain verdict you can screenshot straight into a support ticket. Path MTU now flags values under 1280 as filtered test packets (carrier NAT or a tunnel), not a real link limit. ### 1.4.4 — 2026-08-20 • New-network detection: NetDiag+ notices when your device is on a different network and suggests re-checking the MTU — with a banner in the app, or an optional notification (enable it in Settings). • Share results as an image: Path MTU and Speed Test now export a clean, branded card. • Router guides: where to find the MTU field on Huawei, ZTE, TP-Link, Zyxel and Nokia routers — right under your result. • Host Monitor notifications are now localized, plus small improvements. ### 1.4.3 — 2026-08-17 • NetDiag+ now speaks Arabic — 13 languages with full right-to-left support. • Path MTU redesigned: one clear recommended value and a "What to do next" guide — router won't let you change MTU? Using a VPN? You'll find answers right under the result. • You can now set your own target host for Path MTU discovery. • Localization fixes throughout the app and stability improvements. ### 1.4.2 — 2026-08-04 Fixed traceroute/MTR: the route no longer stops at an intermediate hop behind a firewall — the full path to the destination is shown again. Faster, more stable speed test. Fixed a false "SNI block" in Site Reach on slow connections. ### 1.4.1 — 2026-06-03 Stability fixes: resolved a crash some users could hit during ping, traceroute and other network tools.
