How to Forget a Public WiFi Network on Android
Public hotspots can be convenient, but Android devices often remember them longer than you expect.
If you want to remove a saved hotspot, reduce automatic reconnection, or clean up network settings, this guide shows exactly how to forget public WiFi network on Android.
Forgetting a network is a small step, but it can help with privacy, reduce connection problems, and prevent your phone from reconnecting to insecure WiFi without warning.
Why forget a public WiFi network?
Android stores WiFi details such as the network name, security type, and saved credentials.
When a phone sees that network again, it may reconnect automatically unless you remove it.
- Privacy: Prevents your device from automatically joining open or semi-trusted hotspots.
- Security: Reduces exposure to rogue access points and malicious captive portals.
- Stability: Fixes repeated “connected, no internet” issues on problematic networks.
- Control: Helps you keep only the networks you actually use.
This is especially useful for airport WiFi, hotel WiFi, coffee shop hotspots, campus networks, and other public access points that you may not want saved permanently.
How to forget public WiFi network on Android
The exact labels can vary by manufacturer, but the process is similar across Samsung, Google Pixel, OnePlus, Motorola, Xiaomi, and other Android devices.
Method 1: Forget the network from WiFi settings
- Open Settings.
- Tap Network & internet or Connections.
- Tap Wi‑Fi.
- Find the public network in your saved or connected list.
- Tap the network name or the gear icon.
- Select Forget, Forget network, or Remove.
Once removed, your Android phone will no longer auto-connect unless you manually sign in again and save it later.
Method 2: Forget a saved network from Advanced or Known Networks
Some Android versions place saved hotspots in a separate list.
- Go to Settings.
- Open Network & internet or Connections.
- Tap Wi‑Fi.
- Look for Saved networks, Known networks, or Manage networks.
- Select the public WiFi network.
- Tap Forget or Remove.
Method 3: Remove the network after connecting
If you are currently connected, you can usually forget the network right from the active connection screen.
- Open Settings.
- Tap the active WiFi network.
- Choose Forget.
This is the fastest option when you just used a hotspot and want to erase it immediately.
What happens when you forget a WiFi network?
Forgetting a network removes the saved connection profile from your device.
Your phone stops using the stored settings for that hotspot, including automatic reconnection.
- You may need to re-enter a password if the network is secured.
- Previously accepted login pages for captive portals may no longer be remembered.
- Your phone will no longer prioritize that hotspot over other known networks.
- The network will disappear from the saved list on most Android devices.
For public WiFi, this is usually desirable because it reduces the chance of reconnecting in the background when you are nearby.
How to stop Android from reconnecting to public WiFi?
Forgetting the network is the most direct option, but Android also includes settings that help limit automatic behavior.
Turn off auto-connect for a specific network
On some devices, a network detail page includes an Auto-connect toggle.
If you want to keep the network saved but prevent automatic use, disable that toggle instead of forgetting it.
Disable WiFi scanning when not needed
Depending on the version of Android, features like location-based scanning can help the device find networks more aggressively.
If you want tighter control, review these options:
- Wi‑Fi scanning
- Bluetooth scanning
- Adaptive connectivity
These are not always the cause of auto-connection, but they can contribute to frequent network detection.
Review saved passwords and network preferences
If your device remembers many hotspots, it may connect to one you used months ago.
Cleaning up the saved list keeps your phone focused on trusted networks at home, work, or school.
What if the Forget option is missing?
Some Android skins or older versions hide the option in different menus.
If you cannot find it immediately, try these alternatives:
- Tap the network name instead of the gear icon.
- Open the advanced settings on the WiFi page.
- Check under Saved networks or Manage networks.
- Use the search bar in Settings and search for Wi-Fi or network.
If the hotspot was added through a work profile, MDM policy, or carrier-specific settings, removal may be restricted by an administrator.
How to tell if a public WiFi network is still saved?
After you forget a network, it should no longer appear in the saved list.
If it still shows up, it may be stored in another profile or synced feature.
- Check Saved networks or Known networks.
- Look under Google account or device sync features if available.
- Restart WiFi and re-open the settings screen to refresh the list.
If the hotspot keeps returning, the issue may be caused by an app, a carrier tool, or an enterprise policy rather than normal Android WiFi memory.
Best practices for public WiFi on Android
Forgetting a network is helpful, but public WiFi is safest when combined with a few basic habits.
- Use a VPN: Encrypts traffic on untrusted networks.
- Avoid sensitive logins: Limit banking or password changes on open hotspots.
- Turn off sharing: Disable file sharing, hotspot sharing, and unnecessary discovery features.
- Keep Android updated: Security patches help protect against wireless and browser threats.
- Prefer HTTPS: Ensure websites use encrypted connections.
These practices help protect your data even when you must use public access points.
Troubleshooting after forgetting a network
If WiFi behaves oddly after you remove a network, the issue is usually temporary.
A few quick checks can help.
- Toggle WiFi off and on to refresh the radio.
- Restart the phone if the network list does not update.
- Reset network settings only if you have broader connectivity problems, since it removes Bluetooth and mobile network preferences too.
- Reboot the router or hotspot if a private network is also acting unstable.
Network resets should be a last resort because they clear more than just WiFi history.
Device-specific notes
Android manufacturers often rename the same feature, so the wording may differ slightly.
- Samsung Galaxy: Often uses Connections and then Wi‑Fi, with a gear icon next to the network.
- Google Pixel: Commonly shows Internet in Settings, then Saved networks.
- OnePlus and Oppo: May place options under Wi‑Fi & Network or similar connectivity menus.
- Xiaomi and Redmi: May group options under Connection & sharing or Wi‑Fi.
Even when labels change, the core action is the same: open the network’s details and choose the option to forget or remove it.
When should you forget a public WiFi network immediately?
There are a few situations where removing the hotspot right away is the safest choice.
- You connected to an open network with an unknown owner.
- The network name looked like a duplicate or suspicious variation of a legitimate hotspot.
- Your browser redirected to an unexpected login page.
- The connection repeatedly failed or produced certificate warnings.
- You no longer plan to return to that location.
In these cases, forgetting the network reduces the chance that your phone reconnects later without your attention.
