See Who Is Connected to My WiFi and Block Them
See who is connected to your WiFi from the router device list, spot unknown devices and block them by changing your password or using MAC blocking.
- Log in to your router admin page (for example 192.168.1.1).
- Open Connected Devices, Attached Devices or Client List.
- Match each name to your own devices.
- Block unknown devices, then change your WiFi password.
I have wondered who is using my WiFi when the internet slows down. A neighbor on your network, or a device you forgot about, can eat up the speed you pay for.
Your router keeps a list of every device on your network. This guide shows you how to find that list and block anyone who should not be there. Sign in to your router to see every device on your WiFi and block the ones you do not know.
Check connected devices in your router
In my experience, this is the part that trips most people up.
- Log in to your router, usually at 192.168.1.1 or 192.168.0.1.
- Look for Attached Devices, Connected Devices, Client List, DHCP Clients or Device Manager.
- Review each device name, IP address and MAC address.
Where to find the device list on popular routers
I have seen this done wrong more than once, so I keep it simple here.
| Router | Menu |
|---|---|
| TP-Link | Network Map, Clients (or Advanced, DHCP Client List) |
| Netgear | Attached Devices |
| ASUS | Network Map, Clients |
| Linksys | Device List |
| D-Link | Home, Connected Clients |
| Xfinity | Xfinity app, WiFi, Connected devices |
| AT&T | 192.168.1.254, Home Network, Devices |
| Google Nest Wifi | Google Home app, Wi-Fi, Devices |
How to spot an unknown device
I check this before I change anything else.
- Count your own devices: phones, laptops, TVs, consoles, speakers, cameras, smart plugs and printers all appear.
- Read the names: many devices show a brand or model, such as Galaxy-S24 or Roku. Generic names like ESP_1A2B are often smart home gadgets.
- Turn devices off one by one: if an entry disappears when you switch something off, it is yours.
- Check the MAC address: the first six characters identify the maker. Phones may use a private random MAC, so the maker can look unfamiliar.
How to kick someone off your WiFi
I treat this as a quick check, not a deep setting.
- Change the WiFi password. This is the most reliable fix. Everyone must reconnect, and intruders cannot. See our guide to changing your WiFi password.
- Block the device. Most routers let you block a device by MAC address in the client list, access control or parental controls menu.
- Turn off WPS. WPS lets devices join with a PIN or button press and can be abused. Turn it off in the wireless settings.
- Use WPA2 or WPA3 security. Never leave the network open or on old WEP security.
Keep your network secure
I would rather confirm it now than fix it later.
- Use a long, random WiFi password from our WiFi Password Generator.
- Change the router admin password from the default.
- Put visitors and smart devices on a guest network.
- Keep router firmware up to date.
Why there may be more devices than you expect
I always start with the router page for this.
When people first open the connected devices list, they’re often surprised by how long it is. Most of those entries are yours. Smart TVs, speakers, plugs, cameras, games consoles, e-readers, a fridge, a printer and every phone and tablet all count.
Modern phones also use private or random MAC addresses, so one phone might appear more than once with different names. That’s a privacy feature, not an intruder. Before you worry, match names, brands and IP addresses to your own devices.
Rename devices so the list makes sense
In my experience, this is the part that trips most people up.
Most router apps let you give each device a friendly name, like “Aisha’s iPhone” or “Living room TV”. It takes ten minutes once and makes spotting strangers easy forever after.
- Open your router app or connected devices page.
- Turn off WiFi on one device at a time and see which entry disappears.
- Rename that entry, then turn WiFi back on.
- Repeat until every device has a clear name.
