Who Is on My Wi-Fi? How to See Who’s Connected to Your Network

LAS VEGAS —Who is on my WiFi? It is a question many people ask when their internet suddenly slows down or an unfamiliar device appears on their router. Before assuming a neighbor or hacker has gained access, there are several simple ways to see exactly what is connected to your network.

The first thought is an increasingly common one: Who is on my Wi-Fi?

There are legitimate reasons to check. The FBI specifically recommends reviewing device access on your router and disabling unknown or old devices. The Federal Trade Commission similarly advises consumers to inspect the router’s connected-device, wireless-client or DHCP-client list so they know what is attached to the home network.

But there is an important distinction: seeing an unfamiliar name does not prove a neighbor is stealing your Wi-Fi, and a slow connection does not prove you have been hacked.

How to see who is connected to your Wi-Fi

Do not panic if a device is labeled only as “Unknown,” “Generic,” a manufacturer name, or a string of letters and numbers. Router naming is imperfect. A smart television might appear under the name of its Wi-Fi chip manufacturer rather than the television brand printed on the screen.

Why an “unknown device” may actually be your own phone

Modern phones and computers deliberately make device identification less predictable for privacy reasons.

Apple’s Private Wi-Fi Address feature allows iPhones, iPads, Macs, Apple Watches and other Apple devices to identify themselves to Wi-Fi networks using a private MAC address rather than exposing the hardware address everywhere. Apple says newer operating systems can use fixed or rotating private addresses depending on the network and settings.

Android does something similar. Google’s Android documentation notes that devices running Android 10 and later can use a randomized MAC address for a Wi-Fi network.

That means a device you own can appear under an address you do not immediately recognize. It also means comparing MAC addresses is useful, but not always as simple as reading the sticker on a phone.

Does slow internet mean someone is using your Wi-Fi?

No. It is one possibility, but it is far from the only one.

A connection can slow down because several people in the home are streaming at once, a computer is downloading updates, cloud backups are running, a game console is installing a large file, the Wi-Fi signal is weak, nearby networks are creating interference, the router is struggling, or the internet provider itself is experiencing congestion or an outage.

So a speed drop is a reason to investigate — not evidence by itself.

What should I do if someone really is using my Wi-Fi?

If you have eliminated your own devices and a connection clearly does not belong, do not spend the night repeatedly unplugging the router. That only interrupts the connection temporarily.

Instead, change the credential that actually controls access.

Changing the Wi-Fi password will normally require reconnecting your own wireless devices. That is inconvenient, but it is the cleanest response when you believe someone who should not have access already knows the old password.

Will changing my router’s LAN IP address kick someone off?

Not in the way most people mean.

Your router’s LAN address — often something resembling 192.168.1.1, 192.168.0.1 or another private address — identifies the router inside your local network. Changing that address may reorganize the network, but it is not the same as changing the credential used to join the Wi-Fi.

If an unauthorized person already knows your wireless password, changing the router’s local IP address is not a dependable way to keep that person out. Change the Wi-Fi password and secure the router administrator account.

Does unplugging the router stop someone from using it?

Yes — for as long as the router is turned off, because everybody loses the connection.

But if an unauthorized user already knows the Wi-Fi password, that device may reconnect when the router comes back online. Power-cycling can be useful for troubleshooting, but it is not a substitute for changing compromised credentials.

The bigger problem may not be a neighbor at all

There is another reason to take home-router security seriously: criminals do not always need to sit nearby and join your Wi-Fi like an ordinary user.

In 2026, the FBI warned that compromised routers and other home internet-connected devices can be turned into residential proxies, allowing criminals to route malicious traffic through an innocent person’s internet connection and make the activity appear to come from that home or small business.

In a separate March 2026 cyber alert, the FBI said AVrecon malware had been used to compromise routers and other internet-connected devices across roughly 163 countries. The FBI said the related SocksEscort service was believed to have compromised and sold access to about 369,000 devices since 2020.

The lesson is important: someone visibly connected to your Wi-Fi and someone who has compromised the router itself are different security problems. A clean-looking device list does not make router updates, strong admin credentials and secure configuration unnecessary.

When should you replace an old router?

If the router can no longer receive security updates or cannot support WPA2 or WPA3, replacement deserves serious consideration.

The FBI warned in 2025 that end-of-life routers can remain exposed to known vulnerabilities because manufacturers stop releasing security patches. The agency noted that some older devices had been compromised and used as proxy infrastructure.

You do not need to replace a functioning router simply because it is a few years old. The important questions are whether the manufacturer still supports it, whether it receives security updates, and whether it supports modern encryption.

Can someone on my Wi-Fi see what I am doing online?

Simply being connected to the same Wi-Fi network does not automatically give another user a readable copy of everything you do. Modern websites commonly use HTTPS encryption, and devices have their own security controls.

But unauthorized network access is still a problem. A malicious user may probe poorly secured devices, look for shared services or exploit weaknesses elsewhere on the network. A compromised router creates an even more serious concern because the device controls how your traffic reaches the internet.

That is why the safest response is not to argue over whether the mystery device is “just using bandwidth.” If it does not belong on the network, remove it and secure the network.

Knowing what is connected is part of basic home security

For most households, checking the router’s device list takes only a few minutes. The hard part is resisting two opposite mistakes: ignoring devices that truly do not belong, or assuming every unfamiliar label means a hacker is inside the house.

Start with evidence. Identify your devices. Understand that private MAC addresses can make familiar phones look unfamiliar. Then, if something still does not belong, secure the network properly rather than relying on repeated reboots or changing unrelated settings.

The router is the front door between many of your devices and the internet. Knowing who is connected is one of the simplest ways to make sure you still control the key.
