Why and how to remove devices from your WiFi
Disconnecting a device from your WiFi is straightforward: go into the device's WiFi settings, find your network name, and select "Forget" or "Remove". On most phones and tablets, this takes about 10 seconds. On computers, the process is similar but the menu location changes depending on whether you use Windows, Mac, or Linux.
You might disconnect a device because you sold it, gave it away, or no longer use it. Removing old devices makes your network list cleaner and prevents them from automatically reconnecting if they come back into range. If a device is misbehaving — dropping connection, running slowly, or using excessive data — disconnecting and reconnecting it often fixes the problem by forcing it to re-authenticate and get a fresh IP address from your router.
Disconnecting a device from your end (the device itself) is different from blocking it on your router. When you forget the network on a device, that device loses the password and cannot reconnect unless you enter it again. When you block a device on your router, the device still knows the password but the router refuses its connection attempts. Most people need the first option; the second is for situations where you want to prevent a specific device from connecting without erasing its stored password.
Key Takeaways
- On phones and tablets, open WiFi settings, find your network name, and tap "Forget" — the device will no longer connect automatically.
- On Windows computers, go to Settings > Network > WiFi > Manage Known Networks, select your network, and click "Forget".
- On Mac computers, hold Option, click the WiFi icon in the menu bar, select your network, and click "Remove".
- Disconnecting a device from your end erases the stored password; blocking it on your router prevents connection while keeping the password stored.
- If a device keeps dropping connection, disconnecting and reconnecting it usually fixes the problem by forcing a fresh authentication.
Disconnect on iPhone or iPad
Open Settings, then tap WiFi. Find your network name in the list. Tap the information icon (a small circle with an "i") next to the network name. At the top of the screen, tap Forget This Network, then confirm by tapping Forget again. The device will when ready disconnect and will not reconnect unless you manually enter the password again.
If you want to reconnect later, go back to WiFi settings, select the network name, enter the password, and tap Join. The device will remember the password this time until you forget the network again.
Disconnect on Android phones and tablets
Open Settings, then go to Network & Internet or Connections (the exact name varies by manufacturer). Tap WiFi. Find your network name and tap and hold it until a menu appears. Select Forget or Remove. The device will disconnect when ready.
Some Android devices show a different menu: tap the settings icon (gear or three dots) next to the network name instead of holding it. If you do not see your network in the list, make sure WiFi is turned on and you are looking at the available networks, not the saved networks list.
Disconnect on Windows computers
Click the Start button, then go to Settings > Network & Internet > WiFi. On the right side, click Manage Known Networks. Find your network name in the list and click it. Click Forget. Windows will disconnect when ready and will not reconnect unless you manually select the network and enter the password again.
If you cannot find the network in the Manage Known Networks list, it may already be disconnected. You can also forget a network from the WiFi list itself: click the network name, then click Forget at the bottom of the popup.
Disconnect on Mac computers
Hold the Option key and click the WiFi icon in the menu bar (top right of the screen). A dropdown menu will appear showing your connected network and nearby networks. Find your network name in the list. Click it, then click Remove. The Mac will disconnect and will not reconnect unless you manually select the network and enter the password.
If you do not see the Option-click menu, your Mac may be running an older version of macOS. Instead, go to System Preferences > Network > WiFi > Advanced, find your network in the list, select it, and click the minus button to remove it.
Disconnect on Linux computers
The steps depend on your desktop environment and network manager. In most cases, click the network icon in the system tray (usually top right or bottom right), find your network name, right-click it, and select Forget or Remove. Some systems show an edit or settings button instead — click that, find your network, and look for a delete or remove option.
If you use the command line, you can remove a network by editing the NetworkManager configuration files, but the graphical method is faster for most users. If you are unsure which desktop environment you are running, open a terminal and type echo $XDG_CURRENT_DESKTOP to find out.
Block a device on your router instead of forgetting it
If you want to prevent a device from connecting without erasing its stored password, you can block it on your router instead. Log into your router's admin panel (usually by typing your router's IP address into a web browser — check your router's label or manual for the address). Look for a section called Connected Devices, Device Management, MAC Filtering, or Parental Controls.
Find the device you want to block by its name or MAC address (a unique identifier shown in the device's network settings). Select it and choose Block, Deny, or Disconnect. The device will lose connection when ready and will not be able to reconnect even if it knows the password. To unblock it later, return to the same menu and select Allow or Unblock.
Blocking is useful if you want to temporarily prevent a device from using your network — for example, limiting a child's device access at bedtime — without making them re-enter the password when you want to allow it again. Forgetting the network is better if you are removing a device permanently or if you sold or gave away the device.
Troubleshooting: Device keeps reconnecting after you forget it
If a device reconnects even after you forget the network, it may have the password saved in multiple places. On phones and tablets, check Settings > Accounts or Cloud to see if the network password is synced across devices (iCloud on Apple devices, Google Account on Android). If it is, the device may be pulling the password from the cloud. Remove the network from all synced devices or turn off password sync temporarily.
On computers, check whether a VPN app, password manager, or network utility is storing the password. Some enterprise software automatically reconnects to corporate networks. If you own the device, you can usually disable this in the app's settings. If it is a work device, contact your IT department.
If the device still reconnects after forgetting the network and checking for synced passwords, try restarting the device. A restart clears temporary network settings and often solves persistent reconnection problems.
Frequently Asked Questions
Does disconnecting a device from WiFi affect the device's other functions?
No. Disconnecting from WiFi only removes the stored network password and breaks the wireless connection. The device itself works normally — it just will not connect to that network again unless you manually enter the password. Cellular data, Bluetooth, and other features are unaffected.
Can I disconnect a device from my WiFi if I do not have access to that device?
Not by forgetting the network on the device itself — you need physical access to the device for that. However, you can block the device on your router without touching it. Log into your router, find the device in the connected devices list, and select block or deny. The device will disconnect when ready and cannot reconnect.
Will the device owner know I disconnected or blocked them?
They will notice the connection drops and will not be able to reconnect if you blocked it on the router. If you only forgot the network on the device itself, they will not know unless they try to connect and find the password no longer works. There is no notification sent to the device.
What is the difference between forgetting a network and turning off WiFi?
Turning off WiFi disables the radio temporarily — the device still remembers the password and will reconnect when you turn WiFi back on. Forgetting the network erases the stored password, so the device cannot reconnect without you entering it again. Forgetting is permanent until you manually reconnect; turning off WiFi is temporary.
If I disconnect a device, will it slow down my WiFi for other devices?
Possibly, but usually not much. Removing a device frees up a small amount of bandwidth and router processing power, especially if that device was actively using the network. If a device was stuck trying to reconnect repeatedly, removing it can actually improve performance for other devices.
