Netutilus Internet Check: the router answers but packets are lost past it, so the verdict is “Most likely your provider”, with every tool listed in the sidebar — Internet Check, free: tests the Mac, the router, the internet, DNS and the web, then says whether the problem is your network or your provider.

FAQ

What replaced Network Utility on the Mac?: Apple deprecated Network Utility in macOS Big Sur and removed it in Monterey, leaving ping, traceroute, whois and port scans to the Terminal. Netutilus puts them back in a native window, alongside the LAN, Wi-Fi and monitoring tools Network Utility never had.
Is Netutilus free?: Yes, and most of it stays free: Internet Check, Speed Test, ping, traceroute, DNS, Whois, SSL, port scanning and the menu bar status. Netutilus Pro is a one-time in-app purchase, never a subscription, that unlocks the LAN Scanner, Wi-Fi tools, Uptime Monitor, MTR, Visual Traceroute and iperf3.
Does it need an account or send data anywhere?: No accounts, no analytics, no tracking. Tools contact only the hosts you test and, for a few lookups such as GeoIP or Speed Test, the service that answers them. The full list is on the Permissions & Privacy page.
Does it use the Terminal underneath?: No. It is sandboxed and never shells out. Results come from Network.framework, CoreWLAN and native ICMP sockets, so every result is the app’s own, not scraped command output.
Which Macs does Netutilus support?: Netutilus requires macOS 14.6 or later and is available on the Mac App Store.
