How to Delete a Wi-Fi Network on a Samsung Galaxy: Step-by-Step Instructions

Smartphone owners Samsung Galaxy Users often need to manage saved networks, especially when their device automatically attempts to connect to an unstable signal source. Removing an old or problematic access point is a basic skill that can help resolve many connection issues. In this article, we'll explore not only standard methods but also hidden system features. Android, available on modern One UI shells.

The process may seem trivial, but the interfaces of different operating system versions have their own nuances. We'll look at the current algorithms for models from Galaxy S20 to the latest Galaxy S24Understanding how to properly manage your network list will allow you to optimize your wireless module and avoid unnecessary battery drain.

Sometimes the system may behave unpredictably, retaining configurations even after attempting to delete them. In such cases, a more in-depth approach is required, including resetting network settings or using the engineering menu. Below are proven methods guaranteed to help you clear the connection list.

Standard uninstall procedure via settings

The most common method available to every user is in the main settings menu. You need to go to the section Settings → Connections → Wi-FiA list of all available and previously used networks is displayed here. Find the desired name in the "Saved Networks" list or in the current list if your device is in range.

Once you've found the target network, click the gear icon next to its name. A detailed menu will open, with a "Delete" or "Forget" button at the bottom of the screen. Clicking this button instantly erases the saved password and IP address configuration for this access point.

⚠️ Note: If you delete a network you're currently connected to, your connection will be disconnected immediately. Make sure you have mobile data or are within range of another known network.

It is important to note that on some versions of the shell One UI The interface may vary slightly. If you don't see the delete button right away, try tapping the three dots in the corner of the screen or long-pressing the network name in the general list. This often brings up a context menu with additional options.

Managing networks on different Android versions

The logic of working with wireless connections has changed with the release of new versions AndroidOn older versions, such as Android 10 and below, deleting a network was only possible by long-pressing the network name in the general list. Modern versions, starting with Android 11 and above, have moved this function to the detailed menu for each network.

Users Samsung Galaxy Users with One UI 5.0 and later may notice an improved visual interface. It now features the ability to quickly switch between saved networks without going into a deep menu. However, the mechanism for deleting a network remains the same: opening the network properties and selecting the appropriate option.

Differences also affect security. In newer versions of the system, access to the device's MAC address can be randomized for each network. When reconnecting after deletion, the system may request confirmation of a new random address, which is normal behavior to protect privacy.

Resetting network settings: a radical solution

If deleting a specific network doesn't help, or the list of saved connections behaves erratically, consider a full network settings reset. This clears all saved Wi-Fi networks, Bluetooth pairings, and mobile data settings, returning them to factory defaults.

To perform this procedure, follow the path Settings → General Settings → Reset → Reset Network SettingsThe system will warn you that all data will be lost. Confirm the action by entering your screen unlock PIN. After rebooting, your phone will be cleared in terms of network configurations.

This method is especially effective when there are constant authentication errors or the phone "sees" the network but cannot connect. Reset settings Eliminates software conflicts in wireless module drivers that may have accumulated over time while using the device.

Using the engineering menu and hidden codes

For advanced users who want to access hidden diagnostic functions, there's an engineering menu. It can be accessed via a standard dialer by entering a code. ##4636## or *#0011# (the code may differ depending on the region and processor model).

In the testing menu, select "Wi-Fi" or "Wi-Fi Status." Here you can view technical information about the current connection, the signal strength in dBm, and even execute the "Disconnect" or "Stop Scan" commands. However, be careful: changing the parameters in this menu may cause instability in the module.

Some codes allow you to reset the radio interface without a full phone reboot. This is useful if the Wi-Fi module is frozen and no longer responds to user commands. Using these tools requires precision and an understanding of what you're doing.

The danger of the engineering menu

Changing settings in the engineering menu may void your warranty or cause software failure. Use this only if standard methods fail.

Problems with corporate and hidden networks

Corporate networks that require certificates or EAP configuration are particularly challenging. Often, after a user leaves the organization or changes their password, the phone continues to attempt to connect, blocking other apps. Removing such a network can be difficult if the device has administrator rights.

If the "Delete" button is grayed out or the network appears again after a reboot, check the section Settings → Biometrics and security → Other security settings → Device administratorsA profile may be enabled here, which sets network policies. Disabling this profile will remove the network.

Also worth mentioning are hidden networks (Hidden SSIDs), which don't broadcast their name. To "forget" such a network, select "Add Network" in the Wi-Fi menu, enter the exact name (case-sensitive), and in the security settings, select "Never Connect" or simply enter an incorrect password and delete the entry.

Common mistakes and how to fix them

One of the most common errors is the message "Unable to obtain an IP address." This often occurs when the router has run out of addresses or the phone has "remembered" a static IP address that is no longer relevant. In this case, deleting the network and reconnecting usually resolves the issue.

Another issue is constant connection interruptions after a system update. This is due to changes in power-saving algorithms in new versions. AndroidThe system may aggressively disable Wi-Fi in sleep mode. Check your battery settings and exclude critical apps from optimization.

⚠️ Note: The settings interface may change with firmware updates. If you don't find the item described, use the settings search (magnifying glass at the top of the screen) and enter the keyword "Wi-Fi" or "Network."

Keep in mind that sometimes the problem isn't with your phone, but with the router itself. An overloaded router cache can cause connection errors on any device. Regularly rebooting your home equipment is a simple preventative measure for many network issues.

Questions and Answers

Will resetting network settings delete my browser history?

No, resetting network settings only affects connection settings: Wi-Fi, Bluetooth, and mobile networks. Your personal files, photos, browser history, and installed apps will remain intact.

Is it possible to restore a deleted network without re-entering the password?

Without a backup of your settings (which Samsung doesn't do by default for networks), you can't automatically restore your password. You'll have to re-enter it or look it up in your router settings if you have access to it.

Why does the phone connect to an open network by itself?

In the Wi-Fi settings, there's a "Connect to open networks" option. When enabled, your phone will automatically search for and connect to available hotspots. Disable this option in the Wi-Fi menu to prevent unwanted connections.

Does deleting a network affect internet speed?

Deleting a network by itself won't speed up your internet. However, if your phone was constantly trying to connect to a weak or unavailable network from your saved list, deleting it will free up the module's resources and may improve the stability of your current connection.
