- Why does it find fewer devices than a scanner on my computer?
- Phones keep apps away from the network’s address table (ARP), which computers can read. NetWho finds every device that answers a ping, a port, Bonjour, UPnP, NetBIOS or Kasa, which is nearly all of them; a device that answers none of those, or one known only by its MAC address, can be missed. lsnet, on a Mac or Linux computer, sees those too.
- Why is a device unnamed, or called something generic?
- A device that says little about itself gets named by what it does say: its address, then its open ports. Tap it to see what NetWho heard. Give it a name and a type yourself, and NetWho remembers them on that network.
- Why does it ask for location?
- Only if you turn on “Use Wi-Fi names”. Phones treat the Wi-Fi network’s name as location, so reading it needs that permission. NetWho uses the name to tell your networks apart and label them, and never reads your location.
- On iPhone, it asks to find devices on my local network.
- That’s iOS’s Local Network permission, and NetWho can’t scan without it. If you said no, turn on Local Network for NetWho in Settings.
- How do I open my NAS’s admin page?
- Tap the NAS, then Open. For Synology, UGREEN and QNAP NAS, NetWho goes to the admin page (DSM, UGOS, QTS), not the placeholder web server.
- Does it cost anything, or show ads?
- No. NetWho is free, with no ads, no accounts and no in-app purchases, and it collects no data.
