Introduction

Wireless networks are everywhere. Your laptop, phone, tablet, and even your smart refrigerator probably remember dozens of WiFi networks you have joined over the years. While that convenience is useful most of the time, there are moments when you need to make a device stop remembering a network entirely. Maybe the password changed, maybe you are troubleshooting a stubborn connection, or maybe you are selling a device and want to wipe its wireless history. Whatever the reason, knowing How to Completely Forget Wifi Network? is an essential skill for anyone who uses modern technology.

This guide walks you through the process on every major operating system. It also explains what happens behind the scenes when you forget a network, why the option sometimes disappears, and what to do if a network keeps coming back. You will find step-by-step instructions for Windows, macOS, Android, iPhone and iPad, Linux, and ChromeOS. There is also a comparison table, troubleshooting advice, command-line options, and security best practices.

By the end of this article, you will know exactly how to remove a saved wireless profile from any device and how to keep it from returning.

What Does It Mean to Forget a WiFi Network?

When your device connects to a wireless network, it does more than just join for the moment. It saves a wireless profile that includes the network name, also called the SSID, the security type, and the password or security credentials. The next time your device sees that network, it can connect automatically without asking you for the password again.

Forgetting a network deletes that saved profile. After you forget a network, your device will no longer remember the password. It will not attempt to join automatically. If you want to connect again later, you will have to select the network from the list and enter the credentials from scratch.

It is important to understand that forgetting a network does not affect the router or the network itself. Other devices will continue to work normally. You are only removing the memory of that network from the specific device you are using.

Why You Might Want to Forget a WiFi Network?

There are many practical reasons to remove a saved wireless profile. You might be dealing with a network whose password was recently changed. If your device keeps trying to connect with the old password, it can cause authentication failures and connection loops. Forgetting the network clears the bad credentials so you can enter the new ones.

Security is another common reason. If you connected to a public WiFi network at a coffee shop, airport, or hotel, you probably do not want your device to remember it forever. Saved public networks can be a privacy risk, especially if malicious actors set up rogue access points with the same names. Removing them reduces your attack surface.

You might also want to forget a network when you are troubleshooting. Corrupted wireless profiles can cause slow speeds, dropped connections, or limited connectivity. Deleting and re-adding the network is a standard troubleshooting step. Similarly, if you are giving away or selling a phone, tablet, or laptop, forgetting personal networks helps protect your home WiFi credentials from falling into the wrong hands.

How to Completely Forget Wifi Network? on Windows

Windows stores wireless profiles in the system settings, and you can remove them through the graphical interface or the command line. Below are the most reliable methods.

Using the Settings App

  1. Open the Start menu and select Settings.
  2. Go to Network & internet, then choose WiFi.
  3. Click on Manage known networks. On Windows 11, this may appear under WiFi settings as a list of saved networks.
  4. Find the network you want to remove from the list.
  5. Click the Forget button next to that network.
  6. Confirm the action if prompted. The network profile will be deleted immediately.

If you are using Windows 10, the path is slightly different. Go to Settings, then Network & Internet, select WiFi, and click Manage known networks. Select the network and click Forget.

Using Command Prompt

If the graphical method does not work, or if you prefer the command line, you can use the netsh tool.

  1. Press the Windows key, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type the following command to see all saved wireless profiles:
netsh wlan show profiles
  1. Locate the name of the network you want to forget in the list.
  2. Run the following command, replacing NETWORKNAME with the actual SSID:
netsh wlan delete profile name="NETWORKNAME"
  1. Press Enter. You should see a confirmation message that the profile was deleted.

This method is especially useful when a network does not appear in the Settings list or when you are managing multiple devices remotely.

How to Completely Forget Wifi Network? on macOS

Apple handles saved WiFi networks through System Settings or System Preferences, depending on your version of macOS. The steps below cover the most common versions.

macOS Ventura and Later

  1. Click the Apple menu and select System Settings.
  2. In the sidebar, click WiFi.
  3. Click the Details button next to the network you want to forget. If the network is not currently in range, click Advanced at the bottom right.
  4. Look for the network in the list of known networks.
  5. Click the Remove or Forget button next to the network name.
  6. Confirm the removal.

macOS Monterey and Earlier

  2. Open Network.
  3. Select WiFi from the list on the left.
  4. Click the Advanced button.
  5. In the WiFi tab, you will see a list of Preferred Networks.
  6. Select the network you want to remove.
  7. Click the minus (–) button below the list.
  8. Click OK, then click Apply.

If a network keeps returning on macOS, check whether iCloud Keychain is syncing your WiFi passwords across devices. Disabling Keychain syncing temporarily can stop a forgotten network from reappearing on your Mac.

How to Completely Forget Wifi Network? on Android

Android devices vary by manufacturer, but the general process is similar across Samsung, Pixel, Motorola, and other brands.

  1. Open the Settings app.
  2. Tap Network & internet or Connections, depending on your device.
  3. Select Internet or WiFi.
  4. Look for a section labeled Saved networks, Known networks, or WiFi networks.
  5. Tap the name of the network you want to forget.
  6. Tap Forget, Delete, or a trash can icon.
  7. Confirm the action if asked.

On some Android skins, you may need to long-press a saved network name to reveal the Forget option. If you are connected to the network at the time, you may need to disconnect first before the Forget button becomes available.

How to Completely Forget Wifi Network? on iPhone and iPad

Apple’s iOS and iPadOS make it simple to remove a saved wireless profile.

  2. Tap WiFi.
  3. Find the network in the list. If it is not currently visible, make sure WiFi is turned on.
  4. Tap the blue information (i) icon next to the network name.
  5. Tap Forget This Network.
  6. Confirm by tapping Forget again in the popup.

After you forget the network, your iPhone or iPad will no longer join it automatically. If you change your mind, you will need to select the network and enter the password again.

How to Completely Forget Wifi Network? on Linux

Linux distributions use different desktop environments, so the graphical steps vary. However, most modern distributions use NetworkManager, which supports both GUI and command-line removal.

Using GNOME Settings

  1. Open Settings.
  2. Go to WiFi or Network.
  3. Find the saved network, often listed under WiFi Networks or Known Networks.
  4. Click the gear icon or settings button next to the network.
  5. Look for a Forget or Remove option and click it.

Using the Terminal

If you prefer the terminal, nmcli is the standard tool for NetworkManager.

  1. Open a terminal window.
  2. List saved connections:
nmcli connection show
  1. Identify the name of the WiFi connection you want to remove.
  2. Delete it with the following command, replacing CONNECTIONNAME with the actual name:
nmcli connection delete "CONNECTIONNAME"
  1. The connection is removed immediately. You can verify by running nmcli connection show again.

How to Completely Forget Wifi Network? on ChromeOS

Chromebooks store WiFi networks in the system settings, and removing them is straightforward.

  1. Click the clock in the bottom-right corner to open the system menu.
  2. Click the Settings gear icon.
  3. In the left sidebar, select Network.
  4. Click on WiFi.
  5. Look for your saved networks, often listed under Known networks or Saved networks.
  6. Find the network you want to forget.
  7. Click the information icon or the three-dot menu next to it.
  8. Select Forget or Remove.

ChromeOS will delete the saved credentials, and your Chromebook will no longer connect to that network automatically.

Troubleshooting: When You Can’t Forget a Network

Sometimes the Forget option is missing, greyed out, or the network keeps coming back. Here are the most common causes and how to fix them.

The Forget button is greyed out. This often happens when you are currently connected to the network. Disconnect from the network first, then try to forget it. On some devices, you must turn WiFi off and back on before the option becomes clickable.

The network reappears after you forget it. This is usually caused by synchronization services. If you use iCloud Keychain, Google Account sync, or a Microsoft account, your saved WiFi passwords may be restored from the cloud. Disable syncing temporarily, forget the network on all devices, then re-enable syncing if desired.

Enterprise or school networks. Networks that use WPA-Enterprise, certificates, or MDM (mobile device management) profiles may not allow you to forget them easily. These profiles are often installed by an organization and can reappear automatically. You may need to contact your IT department or remove the management profile from the device.

Hidden networks. If you manually connected to a hidden SSID, it might not show up in the standard list of known networks. On Windows, use the command-line method described earlier. On macOS, check the Advanced WiFi preferences. On Android, look for an option to add or manage hidden networks in the WiFi settings.

Forgetting vs. Disconnecting vs. Blocking: A Comparison

It is easy to confuse forgetting a network with other wireless actions. The table below explains the differences so you can choose the right approach for your situation.

Action What It Does Saves Password? Auto-Reconnects? Best For
Forget network Removes saved profile and credentials completely No No Old networks, changed passwords, security concerns
Disconnect Drops the current connection temporarily Yes Yes, usually Short-term break from a network
Turn off WiFi Disables all wireless radios on the device Yes Yes, when WiFi is re-enabled Saving battery or avoiding all networks
Block network Prevents the device from joining a specific SSID Varies by OS No Persistent unwanted networks

Use Forget when you want to erase the network from your device’s memory. Use Disconnect when you only need a temporary pause. Use Turn off WiFi when you want to stop all wireless activity. Blocking is the most aggressive option and is not available on every operating system.

Preventing Automatic Reconnection

Even if you do not want to forget a network permanently, you may want to stop it from connecting automatically. Most operating systems let you disable auto-join while keeping the password saved.

On Windows, go to Settings, then Network & internet, select WiFi, click Manage known networks, choose the network, and turn off Connect automatically. On macOS, open System Settings, go to WiFi, click Details next to the network, and uncheck Auto-join. On Android, tap the saved network in WiFi settings and toggle off Auto-connect. On iPhone, tap the information icon next to the network and turn off Auto-Join.

Disabling auto-join is a good middle ground. You keep the password handy for future use, but your device will not connect without your permission.

Security Best Practices After Forgetting a Network

Forgetting a network is only one part of good wireless hygiene. Here are additional steps to keep your devices secure.

  • Audit saved networks regularly. Every few months, review the list of known networks on your devices and forget any you no longer use.
  • Be cautious with public WiFi. Forget coffee shop, airport, and hotel networks as soon as you leave. Do not let your device remember open networks that do not require a password.
  • Use a VPN on public networks. If you must connect to public WiFi, use a reputable virtual private network to encrypt your traffic.
  • Update your router password. If you forget your home network because you suspect a security breach, change the router’s admin password and WiFi password immediately.
  • Enable WPA3 when available. Newer security standards offer better protection. Forget older WEP or WPA networks and replace them with WPA2 or WPA3.
  • Remove networks before selling a device. Perform a factory reset or at least forget all personal WiFi networks before giving away or selling a phone, tablet, or computer.

Frequently Asked Questions

Q: Will forgetting a network delete my password?
A: Yes. Forgetting a network removes the saved credentials, so you will need to enter the password again if you want to connect in the future.

Q: Can I recover a forgotten network?
A: Not directly. Once a network is forgotten, the password is deleted from that device. If you have the password written down or stored in a password manager, you can re-enter it. Otherwise, you may need to reset the router or contact the network administrator.

Q: Does forgetting a network affect other devices?
A: No. It only removes the profile from the device you are using. Other phones, laptops, and smart devices will continue to remember and connect to the network normally.

Q: Why can’t I see the Forget option?
A: You might be connected to the network, or the network may be managed by an organization. Disconnect first, or check whether a configuration profile is preventing changes.

Q: Is forgetting a network the same as resetting my router?
A: No. Forgetting a network only changes settings on your device. Resetting a router changes the network itself and affects every device connected to it.

Q: How often should I forget old networks?
A: It is a good habit to review and forget old networks every few months, especially after traveling or after changing your home WiFi password.
