Why don't I see all the devices I know are connected?

Some devices — particularly those in aggressive sleep modes or with strict firewall rules — don't respond to the probe packets used in the sweep. They are on the network but don't reply, so they won't appear in the list.

What is a MAC address and what does the vendor name tell me?

A MAC (Media Access Control) address is a hardware identifier unique to each network interface. The first three bytes identify the manufacturer, so the vendor name tells you who made the network chip — e.g. 'Apple', 'Samsung', 'Espressif' (common in cheap IoT devices).

How long does the scan take?

A typical /24 subnet (254 addresses) completes in 5 to 15 seconds because all addresses are probed concurrently. Larger subnets take proportionally longer.

Does the scan affect my network or slow it down?

The probe packets are tiny and the sweep is brief, so the impact on normal traffic is negligible. You won't notice any slowdown on a home network.

SCAN TO INSTALL

What it does

LAN Devices scans your local network and discovers every active device on it — giving you each device's IP address, MAC address, and vendor name (derived from the MAC prefix) so you can see exactly what's connected to your router at any moment. It's perfect for spotting an unknown device that shouldn't be there, building an inventory of your smart-home gadgets, checking whether a specific device is online, or troubleshooting IP conflicts. The scan runs a concurrent sweep of your subnet directly from your device, with no data ever leaving your network. It's free, private by design, and needs no account or sign-up.

How to use the LAN Devices

Connect to the Wi-Fi network you want to scan, then open the LAN Devices tool.
Tap Scan. The tool sweeps all addresses in your subnet concurrently and populates the list as devices respond.
Review the results: each row shows the device's IP, its MAC address, and the vendor name identified from the MAC prefix.
Tap any device to see its details expanded. Compare against your known devices to spot anything unexpected.
Tap Rescan at any time to refresh the list — useful if a device just came online.
