Introduction

Every device you own remembers the WiFi networks you have ever connected to. That list quietly grows over time — your home network, the coffee shop down the street, a hotel you visited two years ago, and that random open network you accidentally joined once. While this memory is convenient, it can also cause problems. Your phone or laptop may try to connect to a weak or insecure network just because it is saved, or you may find your connection dropping as the device jumps between remembered networks. If you have ever wondered, How Do You Delete Wifi Networks?, you are in the right place.

This guide walks you through removing saved WiFi networks on every major platform: Windows, macOS, iPhone, iPad, Android, Chromebook, and Linux. You will also learn why deleting old networks matters, how to do it from the command line, and what to do when a network refuses to disappear. Whether you are troubleshooting a stubborn connection or just cleaning up your device, the steps below are clear, tested, and easy to follow.

Why You Might Want to Delete WiFi Networks

Before jumping into the steps, it helps to understand why removing old networks is worth your time. There are several practical reasons.

First, security. If you once connected to an open or poorly secured public network, your device may automatically reconnect to it later without asking. An attacker running a rogue hotspot with the same name could intercept your traffic. Deleting that network removes the risk entirely.

Second, performance. When multiple saved networks are in range, your device may spend time scanning and switching between them. This can cause slow connections or dropped video calls. A clean list means faster, more stable connections.

Third, privacy. Your saved network list reveals where you have been — home, work, favorite cafes, hotels. If someone gains access to your device or your account, that list is a trail of your movements. Clearing it protects your privacy.

Finally, troubleshooting. When a network’s password changes or its settings are updated, your device may keep trying the old configuration and fail to connect. Forgetting and re-adding the network is often the fastest fix.

How Do You Delete Wifi Networks on Windows

Windows keeps a list of every WiFi network you have joined, along with its password and settings. You can remove networks through the Settings app or with a quick command. Here is how to do both.

Deleting WiFi Networks on Windows 10

  1. Click the Start menu and select Settings (the gear icon).
  2. Go to Network & Internet, then click WiFi in the left panel.
  3. Scroll down and click Manage known networks.
  4. You will see a list of every saved network. Click the one you want to remove.
  5. Click Forget. The network disappears immediately.

If you prefer a faster route, you can also click the WiFi icon in the taskbar, right-click a network name, and choose Forget. This works for networks currently in range.

Deleting WiFi Networks on Windows 11

  1. Open Settings from the Start menu.
  2. Select Network & internet, then WiFi.
  3. Click Manage known networks.
  4. Find the network and click the Forget button next to it.

Windows 11 groups networks more cleanly, but the process is nearly identical to Windows 10. You can also remove a network from the quick settings panel by right-clicking it and selecting Forget.

Deleting WiFi Networks from the Command Line

If you manage many machines or want to script the cleanup, the command line is the most efficient tool. Open Command Prompt or PowerShell as an administrator and run:

netsh wlan show profiles

This lists every saved network. To delete one, run:

netsh wlan delete profile name="NetworkName"

Replace NetworkName with the exact name of the network, including spaces and capitalization. To delete all saved profiles at once, use:

netsh wlan delete profile name=* i=*

This single command wipes the entire WiFi history, which is useful when handing a laptop to a new user or preparing a device for resale.

How Do You Delete Wifi Networks on macOS

macOS stores preferred networks in System Settings (or System Preferences on older versions). Removing them takes only a few clicks.

  1. Click the Apple menu and choose System Settings (or System Preferences on macOS Monterey and earlier).
  2. Select WiFi in the sidebar.
  3. Click Advanced (or Details on newer versions).
  4. Under Preferred Networks, select the network you want to remove.
  5. Click the minus (–) button and confirm.

On older macOS versions, you may need to click Remove instead of the minus button. If you want to remove all saved networks at once, select them all with Shift-click and then click the minus button.

There is also a command-line option for power users. Open Terminal and run:

networksetup -removepreferredwirelessnetwork en0 "NetworkName"

Replace en0 with your WiFi interface if it differs, and replace NetworkName with the exact SSID. To list all saved networks first, run:

networksetup -listpreferredwirelessnetworks en0

How Do You Delete Wifi Networks on iPhone and iPad

Apple makes it simple to forget a network, but only for networks you are currently connected to or that are in range. Here is the standard method.

  1. Open Settings and tap WiFi.
  2. Find the network in the list. If you are connected to it, it appears at the top with a checkmark.
  3. Tap the i (info) icon next to the network name.
  4. Tap Forget This Network, then confirm.

If the network is not currently in range, it will not appear in the list, so you cannot remove it from the iPhone directly. However, if you use iCloud Keychain, the network may sync across your Apple devices. To remove it everywhere, forget it on a Mac using the steps above, or turn off WiFi syncing in iCloud settings.

One useful tip: if you want your iPhone to stop auto-joining a network without deleting it entirely, tap the i icon and toggle off Auto-Join. This keeps the password saved but stops automatic connections.

How Do You Delete Wifi Networks on Android

Android varies by manufacturer, but the general process is consistent across most phones and tablets.

  1. Open Settings and tap Network & internet (or Connections on Samsung devices).
  2. Tap WiFi (or Wi-Fi).
  3. Tap the gear or settings icon next to the saved network, or long-press the network name.
  4. Select Forget or Forget network.

On Samsung Galaxy devices, the path is Settings > Connections > WiFi > tap the gear icon > Forget. On Google Pixel phones, it is Settings > Network & internet > Internet > tap the gear > Forget.

To see all saved networks, including those not in range, go to Settings > Network & internet > WiFi > Saved networks (on Pixel) or Settings > Connections > WiFi > Advanced > Manage networks (on Samsung). From there you can forget any network in the list.

If you use a Google account with WiFi sync enabled, forgetting a network on one Android device may remove it from others signed into the same account. You can manage this in Settings > Google > Backup > WiFi passwords.

How Do You Delete Wifi Networks on Chromebook

Chromebooks store networks in Chrome OS settings. The process is straightforward.

  1. Click the time in the bottom-right corner to open the system tray.
  2. Click the WiFi icon, then click the gear icon to open Settings.
  3. Under Network, click WiFi.
  4. Find the network in the list and click the three-dot menu next to it.
  5. Select Forget.

If the network does not appear, click Known networks at the bottom of the WiFi list to see all saved networks, including those out of range. From there you can forget any of them.

For Chromebooks managed by a school or employer, some networks may be pushed by policy and cannot be removed manually. In that case, contact your IT administrator.

How Do You Delete Wifi Networks on Linux

Most Linux distributions use NetworkManager to manage WiFi. You can remove networks through the graphical interface or the terminal.

Using the Graphical Interface

  1. Open Settings and go to WiFi or Network.
  2. Click the gear icon next to a saved network.
  3. Select Forget or Remove.

The exact labels vary by desktop environment — GNOME, KDE, and XFCE each look slightly different — but the option is always available in the network settings.

Using the Terminal

NetworkManager provides a powerful command-line tool called nmcli. To list all saved connections, run:

nmcli connection show

To delete a network, run:

nmcli connection delete "NetworkName"

You can also delete by UUID, which is useful when two networks share a name:

nmcli connection delete uuid 12345678-90ab-cdef-1234-567890abcdef

For older systems using wpa_supplicant directly, edit the configuration file at /etc/wpa_supplicant/wpa_supplicant.conf and remove the relevant network={...} block, then restart the service.

Comparison of Methods Across Platforms

The table below summarizes how to delete WiFi networks on each platform, so you can quickly find the right approach.

Platform Primary Method Can Delete Out-of-Range Networks? Command-Line Option
Windows 10/11 Settings > Network & Internet > WiFi > Manage known networks Yes netsh wlan delete profile
macOS System Settings > WiFi > Advanced > Preferred Networks Yes networksetup -removepreferredwirelessnetwork
iPhone / iPad Settings > WiFi > tap i > Forget This Network No (only in range) None
Android Settings > Network & internet > WiFi > Saved networks Yes (via Saved networks) None (root required)
Chromebook Settings > Network > WiFi > Known networks Yes None
Linux Settings > WiFi > gear icon > Forget Yes nmcli connection delete

Tips and Best Practices

Keeping your WiFi list clean is an ongoing habit, not a one-time task. These tips will help you stay on top of it.

  • Review your list monthly. A quick check every few weeks prevents the list from growing out of control.
  • Use Auto-Join sparingly. On iPhone and macOS, you can keep a network saved but disable Auto-Join. This is ideal for networks you use occasionally but do not want your device connecting to automatically.
  • Forget before you travel. Hotel and airport networks are often open and insecure. Remove them as soon as you leave so your device does not reconnect later.
  • Update passwords, then forget and re-add. When a network’s password changes, forgetting the old entry and reconnecting fresh avoids authentication errors.
  • Back up before wiping. If you are deleting all profiles on a work machine, make sure you have the credentials for networks you still need.
  • Check cloud sync. Networks saved on one device may sync to others through iCloud, Google, or Microsoft accounts. Delete from the source or disable sync to avoid surprises.

Troubleshooting When a Network Will Not Delete

Sometimes a network refuses to disappear. Here are the most common causes and fixes.

  • The network is managed by policy. On work or school devices, administrators may push WiFi profiles that cannot be removed by the user. Contact IT support.
  • Cloud sync keeps restoring it. If you delete a network but it reappears, check iCloud Keychain, Google WiFi sync, or your Microsoft account. Disable sync or delete from the cloud source.
  • The interface name is wrong (Linux/macOS). Double-check your WiFi interface name with ifconfig or ip link before running terminal commands.
  • Case sensitivity matters. Network names are case-sensitive on most platforms. Copy the exact name rather than typing it.
  • Restart after changes. A reboot clears cached connection data and ensures the deletion sticks.
  • Reset network settings as a last resort. On iPhone, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This wipes all WiFi, cellular, and VPN settings, so use it only when nothing else works.

Frequently Asked Questions

Does forgetting a WiFi network delete the password?

Yes. When you forget a network, your device removes the saved password and all associated settings. You will need to re-enter the password the next time you connect.

Will deleting a WiFi network disconnect me right now?

If you are currently connected to that network, forgetting it will disconnect you immediately. If you are connected to a different network, deleting an unused one has no effect on your current connection.

Can I recover a forgotten WiFi network?

There is no undo button. However, you can simply reconnect to the network and re-enter the password. If you do not remember the password, check your router, your password manager, or ask the network administrator.

Why does a deleted network keep coming back?

This usually happens because of cloud sync. Your account may be restoring the network from another device. Disable WiFi sync in your account settings, or delete the network from all your devices at once.

Is it safe to delete all WiFi networks at once?

Yes, it is safe. Your device will simply have no saved networks and will prompt you to connect to one the next time you need internet. Just make sure you know the password for the network you want to use.

Does deleting a network improve battery life?

Marginally, yes. A shorter list means less scanning and fewer background connection attempts, which can slightly reduce battery drain, especially on mobile devices.

How do I delete a WiFi network I am not currently connected to?

On Windows, macOS, Android, Chromebook, and Linux, you can view and delete all saved networks regardless of whether they are in range. On iPhone and iPad, you can only forget networks that are currently visible in the WiFi list.

What is the difference between “Forget” and “Disconnect”?

Disconnect temporarily drops your current connection but keeps the network saved for later. Forget permanently removes the network and its password from your device.

Conclusion

Now you know exactly How Do You Delete Wifi Networks? on every major platform. Whether you are cleaning up a Windows laptop with a quick netsh command, removing old cafes from your iPhone, or tidying up a Linux workstation with nmcli, the process is simple once you know where to look. Regular cleanup improves security, boosts performance, protects your privacy, and makes troubleshooting far easier. Make it a habit to review your saved networks every month, disable Auto-Join for networks you rarely use, and always remove hotel and public networks as soon as you leave. With a clean WiFi list, your devices will connect faster, more reliably, and more securely every time.
