How to Kick Someone Off Your WiFi
If your internet is suddenly slow, you notice an unfamiliar device on your network, or you want to remove someone who should no longer have access — a neighbor who guessed your password, an ex, or an old houseguest — here is how to find them and remove them.
Step 1 — See Who Is Connected
Log into your router admin panel to see every device currently on your network. Open a browser and go to your router's IP:
| Router / ISP | Admin Address |
|---|---|
| NETGEAR, Linksys, ASUS, Spectrum, Verizon | 192.168.1.1 |
| D-Link, TP-Link, Cox, CenturyLink | 192.168.0.1 |
| Xfinity / Comcast | 10.0.0.1 |
| AT&T | 192.168.1.254 |
| Unknown | Find your router IP |
Inside the admin panel, look for a section labelled Connected Devices, Attached Devices, Client List, or DHCP Client List. You will see a list of every device with its IP address, MAC address, and often a device name or hostname.
Identifying unknown devices is the tricky part — many show up as generic names like "android-3f8a2b" or just a MAC address. Count your known devices: phones (everyone in the household), laptops, tablets, smart TV, streaming sticks, game consoles, smart speakers, smart home devices (cameras, bulbs, thermostats, plugs). A typical household of two people easily has 15–25 devices. If the count does not add up, you have a visitor.
Step 2 — Change Your Password (Most Effective)
The fastest and most reliable method. Changing your WiFi password immediately disconnects every device on the network — authorized and unauthorized alike. Only people you give the new password to can reconnect. This method cannot be bypassed.
Full instructions: How to change your WiFi password. After changing it, reconnect your own devices first (phone, laptop) before sharing the new password with others.
This is the right approach when you want to lock out someone entirely or are not sure which device belongs to them — just change the password and only give it to people you trust.
Step 3 — Block a Specific Device (MAC Filtering)
If you want to block a specific device without disconnecting everyone, use MAC address filtering. Every network device has a unique MAC address — a hardware identifier that looks like AA:BB:CC:DD:EE:FF.
- Find the unknown device in the connected devices list in your router admin panel
- Copy its MAC address exactly
- Navigate to the MAC filtering or Access Control section of your router
- Add the MAC address to the deny / block list
- Save — the device is disconnected immediately and cannot rejoin
Where to find MAC filtering by router brand:
| Router | Path |
|---|---|
| NETGEAR | Advanced → Security → Access Control |
| ASUS | Wireless → Wireless MAC Filter |
| TP-Link | Wireless → Wireless MAC Filtering |
| Linksys | Wireless → Wireless MAC Filter |
| D-Link | Advanced → Network Filter |
ISP App — The Easiest Method
If you have an ISP-provided gateway, their app often makes blocking devices easier than using the web admin panel. Most ISP apps let you pause or block a device with a single tap:
| ISP | App | How to Block |
|---|---|---|
| Xfinity | xFi app | Devices → select device → Pause Device |
| Spectrum | My Spectrum app | Services → WiFi → Connected Devices → select → Pause |
| AT&T | Smart Home Manager | Devices → select device → Block Device |
| Verizon Fios | My Fios app | Internet → Devices → select → Pause |
| Cox | Cox app | My Network → select device → Pause |
| Optimum | Optimum app | My Network → Connected Devices → select → Pause |
Note: "Pause" on ISP apps typically blocks internet access for that device but keeps it on the local network. It cannot access the internet but can still see local devices. For complete removal, change your password.
Mesh System Apps
If you have a mesh WiFi system, device management happens entirely in the app — not a web admin panel:
| System | How to Block |
|---|---|
| Eero | eero app → tap the device → Pause. Or block permanently via Access Controls if you have eero Secure |
| Google / Nest WiFi | Google Home app → Wi-Fi → Devices → tap device → Pause Device |
| NETGEAR Orbi | orbilogin.com or Orbi app → Connected Devices → block by MAC |
Prevent Future Unauthorized Access
Use a strong WiFi password — at least 12 characters with a mix of letters, numbers, and symbols. Avoid anything obvious: your address, birthday, or the word "password." See our full WiFi password guide.
Use WPA2 or WPA3 encryption — never WEP (crackable in under a minute) or an open network. See WPA2 vs WPA3 for which to choose.
Change the router admin password — the default admin credentials for your router are published online. Anyone on your WiFi can access your router settings if you have not changed the admin password. See default router passwords and change yours immediately after logging in.
Disable WPS — WiFi Protected Setup (the push-button pairing feature) has known security vulnerabilities. Its 8-digit PIN can be brute-forced in hours. Disable it in your router's wireless settings unless you actively use it.
Set up a guest network — for visitors, smart home devices, and anything you do not fully trust, use a separate guest network. Devices on the guest network can access the internet but cannot see or reach devices on your main network, protecting your computers, NAS drives, and smart home hubs.
Check periodically — log into your router admin once a month and scan the connected devices list. Catching an unauthorized device early is easier than dealing with it after months of access.
