NetScanTW

Who is on my Wi-Fi? NetScanTW finds every device and helps when the internet acts up.

NetScanTW shows you what is going on in your network – no account, no server, no tracking.

FIND DEVICES • Scans your Wi-Fi or Ethernet and lists every device with address, name, and response time • Recognizes routers, printers, TVs, NAS, smart home devices, consoles, and more • Network map: your network as a picture, with the router in the middle

TOOLS • Ping with chart, loss, and jitter • Traceroute to any destination • DNS lookup with every record type and a choice of servers • Port check, in the network and on the internet • Bonjour services: AirPlay, printers, file sharing • LAN throughput: measures what your Wi-Fi really manages between two devices running NetScanTW

ON THE MAC, ALSO • MAC addresses and vendors, custom names, comments, and a notice for new devices • Speed test with latency under load (bufferbloat) • Connection monitor: logs every outage and tells whether the Wi-Fi or the provider was to blame • Security check: open Telnet and database ports, UPnP forwardings, ARP spoofing, stray DHCP servers, Wi-Fi encryption • Wi-Fi channels with a recommendation, web check with TLS certificate, whois, subnet calculator, the router's port forwardings, Bluetooth devices nearby • Widget, Shortcuts, and a command line for scripts

Your custom device names from the Mac show up on the iPhone through iCloud. One purchase covers Mac and iPhone.
