Introduction

Have you ever connected your laptop, phone, or tablet to a Wi-Fi network and later wished you could make your device “forget” it completely? Whether you’re dealing with a changed password, a network that no longer exists, or simply want to clean up your saved connections list, learning How to Forget Network Wifi? is a surprisingly useful skill. The phrase “disconnect and forget” captures exactly what most people want: not just to leave a network temporarily, but to erase it from the device’s memory so it never auto-connects again.

In this guide, we’ll walk through everything you need to know about disconnecting and forgetting Wi-Fi networks across all major platforms—Windows, macOS, iPhone, Android, and even Linux. We’ll also cover troubleshooting tips, best practices, and answers to common questions so you can confidently manage your wireless connections.

What Does “Forget Network” Actually Mean?

When you connect to a Wi-Fi network, your device saves the network name (SSID) along with its security credentials—usually the password. This saved profile allows your device to automatically reconnect whenever that network is in range. “Forgetting” a network deletes this saved profile entirely. After forgetting, your device will no longer recognize the network as a trusted connection and will not auto-connect to it.

It’s worth noting that forgetting a network only affects your local device. It doesn’t remove the network from existence, block other devices, or change anything on the router. Think of it as clearing a bookmark from your own browser—other people’s bookmarks remain untouched.

Why You Might Want to Forget a Wi-Fi Network

There are many legitimate reasons to forget a saved Wi-Fi network:

  • Password changed: The network administrator updated the Wi-Fi password, and your device keeps trying (and failing) to connect with the old one.
  • Network renamed or removed: The SSID changed or the router was replaced, leaving a ghost entry in your saved list.
  • Privacy and security: You connected to a public or hotel network and don’t want your device auto-connecting to it later.
  • Troubleshooting: Forgetting and re-adding a network often fixes connection glitches.
  • Decluttering: A long list of old networks makes it harder to find the ones you actually use.
  • Switching networks: You want to force your device to prefer a different network with a stronger signal.

Disconnect vs. Forget: What’s the Difference?

These two actions sound similar but behave very differently. Disconnecting simply ends your current session with the network. Your device remains connected to the network’s profile, and the next time you’re in range, it will automatically reconnect. Forgetting, on the other hand, deletes the saved profile entirely. After forgetting, your device treats the network as unknown and will require you to enter the password again if you ever want to reconnect.

If you only want a temporary break—say, to switch to a mobile hotspot—disconnecting is enough. If you want a permanent removal, you need to forget.

How to Forget a Wi-Fi Network on Windows 11

Windows 11 offers a clean, modern interface for managing Wi-Fi networks. Here’s the step-by-step process:

  1. Click the Start button and open Settings.
  2. Navigate to Network & Internet > Wi-Fi.
  3. Click Manage known networks.
  4. Find the network you want to remove from the list.
  5. Click the Forget button next to it.

The network will immediately disappear from your known networks list. If you’re currently connected to it, Windows will disconnect first and then forget it.

Quick Method via System Tray

You can also forget a network directly from the taskbar:

  1. Click the Wi-Fi icon in the system tray.
  2. Click the arrow next to the Wi-Fi toggle to expand available networks.
  3. Right-click the network you want to forget.
  4. Select Forget.

How to Forget a Wi-Fi Network on Windows 10

Windows 10 is very similar to Windows 11, with slightly different menu labels:

  1. Open Settings from the Start menu.
  2. Go to Network & Internet > Wi-Fi.
  3. Click Manage known networks.
  4. Select the network you want to remove.
  5. Click Forget.

Alternatively, from the system tray Wi-Fi menu, you can right-click a network and choose Forget. This is often the fastest way when you’re troubleshooting a stubborn connection.

How to Forget a Wi-Fi Network on macOS

On a Mac, forgetting a network requires a few more steps because macOS stores preferred networks in a dedicated list:

  1. Click the Apple menu and select System Settings (or System Preferences on older macOS versions).
  2. Go to Wi-Fi.
  3. Click Advanced or Details (depending on your macOS version).
  4. Under Preferred Networks, select the network you want to remove.
  5. Click the minus (–) button.
  6. Confirm by clicking Remove.

On older macOS versions, you may be prompted to enter your administrator password to authorize the change. Once removed, macOS will no longer auto-connect to that network.

How to Forget a Wi-Fi Network on iPhone (iOS)

Apple makes it easy to forget a network directly from the Wi-Fi settings screen:

  1. Open the Settings app.
  2. Tap Wi-Fi.
  3. Find the network in the list (it may appear under “Known Networks” or with a checkmark if connected).
  4. Tap the info (i) icon next to the network name.
  5. Tap Forget This Network.
  6. Confirm by tapping Forget again.

If you’re currently connected to the network, your iPhone will disconnect immediately and the network will be removed from your saved list. Note that if you have iCloud Keychain enabled, forgetting a network on one Apple device may sync the removal to your other Apple devices signed into the same Apple ID.

How to Forget a Wi-Fi Network on Android

Android interfaces vary by manufacturer, but the general process is consistent:

  1. Open Settings.
  2. Tap Network & Internet (or Connections on Samsung devices).
  3. Tap Wi-Fi or Internet.
  4. Tap the gear icon or the network name you want to forget.
  5. Tap Forget (sometimes labeled “Forget network” or found under “Advanced”).

On some Android skins, you may need to long-press the network name and select Forget network from the pop-up menu. After forgetting, the network will no longer appear in your saved list, and auto-connect will be disabled.

How to Forget a Wi-Fi Network on Linux

On Linux distributions using NetworkManager (the most common), you can forget a network via the GUI or the command line.

Using the GUI

  1. Open Settings > Wi-Fi.
  2. Click the gear icon next to the network.
  3. Select Forget Connection.

Using the Command Line

nmcli connection delete "NetworkName"

Replace "NetworkName" with the actual SSID. This is especially handy for headless servers or when the GUI isn’t responding. You can also list all saved connections first with nmcli connection show to find the exact name.

Linux (NetworkManager) Settings > Wi-Fi or terminal Forget Connection / delete No Use nmcli for command line

Troubleshooting: Network Keeps Coming Back

Sometimes, after you forget a network, it reappears or your device keeps trying to connect. Here are common causes and fixes:

  • iCloud Keychain sync: On Apple devices, a forgotten network may reappear if another device on the same Apple ID still has it saved. Forget it on all devices.
  • Enterprise/MDM profiles: Work or school devices may have configuration profiles that re-add networks automatically. Contact your IT administrator.
  • Router broadcasting same SSID: If the router uses the same SSID on multiple bands, your device may reconnect to the other band. Forget both entries.
  • Windows auto-connect setting: Check that “Connect automatically” isn’t re-enabled when you re-add the network.
  • Cached credentials: On some systems, clearing the network cache or restarting the device after forgetting helps.

If all else fails, restarting your device and router can clear lingering connection states.

Tips and Best Practices

  • Forget before reconnecting: If a network’s password changed, forget it first, then reconnect with the new password. This avoids cached-credential errors.
  • Use airplane mode for quick breaks: If you just want a temporary disconnect, toggling airplane mode or turning off Wi-Fi is faster than forgetting.
  • Audit your saved networks regularly: Periodically review your known networks list and remove old or unused entries for better security.
  • Avoid auto-connect on public Wi-Fi: Disable “Connect automatically” for open networks to prevent accidental connections to potentially unsafe hotspots.
  • Document important passwords: Before forgetting a network you might need later, make sure you have the password stored somewhere safe.
  • Keep firmware updated: Router and device firmware updates can improve connection stability and reduce the need to forget networks.

Frequently Asked Questions

Does forgetting a Wi-Fi network delete it from the router?

No. Forgetting only removes the saved profile from your device. The router and network continue to operate normally for other users.

Will I need the password again after forgetting?

Yes. Once you forget a network, reconnecting requires you to enter the Wi-Fi password again.

Can I undo “forget network”?

There’s no undo button, but you can simply reconnect to the network by selecting it and entering the password. Your device will create a new saved profile.

Why does my device keep reconnecting after I forgot the network?

This is often due to iCloud Keychain sync, MDM profiles, or multiple bands broadcasting the same SSID. Check the troubleshooting section above for detailed fixes.

Is forgetting a network the same as resetting network settings?

No. Forgetting removes one specific network profile. Resetting network settings clears all saved networks, Bluetooth pairings, and VPN configurations at once. Use reset only as a last resort.

Does forgetting improve Wi-Fi speed?

Not directly. However, removing stale or conflicting profiles can help your device connect to the correct, stronger network faster.
