Who is on my WiFi? Find every device on your network

See every device on your Wi-Fi with IP, MAC and vendor

A network scan walks through every address on your home network and reports back what answered. The LAN Devices tool in the Carbide app runs that scan from your phone and lists each connected device with the details you need to identify it. No account, no premium tier for the basics — unlike scanner apps that gate results behind a sign-up.

The scan runs entirely on your phone, inside your own network. Your device list is not uploaded anywhere — it is your network, and the results stay on your device. For each device you will see:

• IP address — where the device sits on your network (for example 192.168.1.7).
• MAC address — the hardware identifier that stays constant even when the IP changes.
• Vendor — the manufacturer looked up from the MAC, like Apple, Samsung or TP-Link.
• Your own phone, marked so you can rule it out immediately.

How to tell which device is which

A scan result like "Espressif, 192.168.1.23" means nothing until you match it to a physical device. The vendor name is your best clue: Apple or Samsung entries are phones, tablets and laptops; names like Espressif, Tuya or Sonoff are almost always smart-home gear — plugs, bulbs, cameras; Hon Hai or AzureWave usually means a TV or console's Wi-Fi module.

For the stubborn ones, use elimination. Count the devices you own, then turn suspects off one at a time — switch off the smart TV, rescan with LAN Devices, and see which entry disappeared. Each device's MAC address is also printed in its settings screen (and often on a sticker), so you can match entries exactly. Once everything you own is accounted for, whatever remains is a guest, a forgotten old gadget — or someone who should not be there.

How to kick someone off your Wi-Fi — the honest answer

No app can genuinely block a device on your network — apps that claim to "kick" devices use tricks the intruder can bypass in seconds. The honest, permanent fix is changing your Wi-Fi password in the router settings. Here is the whole process:

• Find your router's address with Router Info — usually 192.168.1.1 or 192.168.0.1.
• Type that address into your browser and log in (the admin password is printed on the router's label if you never changed it).
• Open the wireless or Wi-Fi security section and set a new, strong password — generate one with the password generator.
• Choose WPA2 or WPA3 security, never WEP or open.
• Save. Every device disconnects instantly — reconnect yours with the new password, and the freeloader is locked out.

Find your router's IP, gateway, DHCP and DNS in one tap

That router login step trips most people up, because finding the gateway address manually means digging through your phone's Wi-Fi details or trying 192.168.1.1 and hoping. The Router Info tool in the Carbide app skips the hunt: one tap shows your gateway IP, subnet mask, DHCP server and lease, and the DNS servers your network is actually using.

Those details do more than open the admin page. The DNS entries tell you whether your traffic resolves through your ISP or a custom server; the DHCP range tells you how many addresses your network can hand out. Note this is all your private, internal address — the IP websites see is different. Check that side with the IP Info tool, and read what is my IP explained for the public-versus-private picture.

Fix slow Wi-Fi: scan channels and pick the clearest one

Sometimes nobody is stealing anything — your Wi-Fi is slow because your router shares a crowded channel with half the building. The WiFi Analyzer tool in the Carbide app scans nearby networks and shows which channel each one occupies and how strong it is, so you can move your router to a clearer one in its settings. On 2.4 GHz, stick to channels 1, 6 or 11 — the only three that do not overlap. The 5 GHz band has far more room and much less interference, but shorter range; use it for devices near the router.

Measure the result instead of guessing: run the speed test before and after changing the channel, and check latency with ping. Both measure against real servers over your connection — the speed test guide explains how to read the numbers.

Why the browser can't scan your Wi-Fi

A fair question: why is this an app and not a web page? Because browsers are deliberately walled off from network radios. A web page cannot sweep your local network for devices, read your router's DHCP lease, or see nearby Wi-Fi channels and signal strengths — that access requires a native app talking directly to the operating system. It is a privacy protection, and a good one.

That is why LAN Devices, Router Info and WiFi Analyzer live in the Carbide app for Android and iOS — coming soon, free, with the same no-account approach as the web tools. Until then, the browser side of your network is fully covered: check your connection with Network Info, your public address with IP Info, and your speed with the speed test — the network info guide walks through all of them.
