How to reset your Wi-Fi password on your phone: detailed instructions for Android and iOS

Connecting to a Wi-Fi network is the first task a new smartphone owner faces, or after a factory reset. It would seem simpler than entering a password. But in practice, users encounter authentication errors, "eternal" connections, or sudden disconnections. This is especially true for public networks (in cafes, hotels, and airports) that require browser authentication, or for dual-band routers with different network names. 2.4 GHz And 5 GHz.

In this article, we will cover not only the basic steps for entering a password on Android And iPhone, but also rare nuances: what to do if the network isn't showing up, how to find saved passwords on your phone, why the device "forgets" the network after an update, and how to bypass MAC address blocking on corporate networks. We'll also cover security—why you shouldn't connect to open networks without a VPN and how to recognize phishing access points.

Basic methods for entering a Wi-Fi password on your phone

On most modern smartphones, the process of connecting to Wi-Fi is standardized, but there are differences between Android And iOSLet's consider both options.

On Android (versions 10 and later):

1. Open Settings (gear icon in the applications menu).
2. Go to the section Network and Internet → Wi-Fi.
3. Activate the slider Wi-Fi (if it is turned off).
4. Select the desired network from the list of available networks. If there is no network, click Refresh or Add a network.
5. Enter the password in the field Password and press Connect.

On iPhone (iOS 15/16/17):

1. Launch the application Settings.
2. Tap on the section Wi-Fi.
3. Make sure the switch is on Wi-Fi on (green).
4. Select a network from the list. If it is hidden, click Another network....
5. Enter the password and confirm the connection.

⚠️ Attention: On some firmware versions Android (For example, MIUI on Xiaomi or ColorOS on Oppo) the Wi-Fi section may be located in Connections and Sharing or Wireless networksIf you can't find it, use the settings search (the magnifying glass icon at the top of the screen).

What to do if the Wi-Fi network is not showing up in the list

If the required network is not visible, there may be several reasons:

• 📶 The network is hidden (SSID is not broadcast). In this case, you need to add it manually (instructions below).
• 🔄 The router is operating in an incompatible range.5 GHz, and the network broadcasts only in this range.
• 🚫 MAC filtering is enabled. Your network administrator may have blocked your device by MAC address.
• 🔋 Problems with the router. Reboot it (pull power off for 30 seconds).

To connect to hidden network:

1. On Android: in Wi-Fi settings, tap Add a network → specify Network name (SSID), select the security type (WPA2-PSK or WPA3-PSK) and enter the password.
2. On iPhone: In the Wi-Fi settings, select Another network... → enter Name And Password, click Connect.

💡 Helpful tip: If the network still doesn't connect, check if your phone supports the standard. Wi-Fi 6 (802.11ax)Some new routers enable this mode by default, which is incompatible with older devices. Try switching to Wi-Fi 5 (802.11ac).

Password Errors: Causes and Solutions

The most common problem is the message "Failed to connect to the network" or "Incorrect password" Even if you are sure that you are entering it correctly, the error may occur for the following reasons:

⚠️ Attention: If you connect to the internet in a public place (such as a hotel or airport), after entering your password, a browser window may open asking you to authorize the connection (enter your room number, agree to the terms and conditions, etc.). Without this, you won't be able to connect to the internet, even if the network shows "Connected."

On some routers (for example, Keenetic or ASUS RT-AX88U) By default, the "Password Attack Protection" feature is enabled, which locks the device after 3-5 unsuccessful attempts. In this case, you will have to wait 5-10 minutes or reboot the router.

How to find a saved Wi-Fi password on your phone

If you've forgotten your network password but your phone is already connected to it, you can find it in the settings. The methods vary depending on Android And iPhone:

On Android (requires root privileges or access to system files):

1. Install a file manager with access to root folders (for example, Root Explorer or FX File Explorer).
2. Follow the path /data/misc/wifi/ or /data/misc/apexdata/com.android.wifi/.
3. Open the file WifiConfigStore.xml and find the line <string name="PreSharedKey">PASSWORD</string>.

⚠️ Attention: On new versions Android (12+) This method may not work due to enhanced data security. An alternative is to use ADB commands (requires USB debugging enabled):

adb pull /data/misc/wifi/WifiConfigStore.xml
adb shell su -c "cat /data/misc/wifi/WifiConfigStore.xml"

On iPhone You can't view the password directly, but you can:

• 🔄 Connect to this network with Mac (if there is one) and look at the password in Keychain.
• 📱 Reset network settings on iPhone (but this will delete all saved passwords).
• 🖥️ View the password on another device already connected to this network (for example, on a laptop with Windows).

How to view your Wi-Fi password on Windows

Open Network Settings → Wi-Fi → Manage Known Networks|Select the desired network and click Properties|Scroll to Network password and press Show symbols

Connecting to Wi-Fi without a password: possible methods

In some cases, you can connect to a network without entering a password, but these methods only work under certain conditions:

• 🔗 WPS (Wi-Fi Protected Setup). If your router supports WPS, press the WPS button on your router, then select the network on your phone and confirm the connection. Dangerous: WPS is vulnerable to brute-force attacks, so it's best to disable it in your router settings.
• 📱 QR code. Some routers (eg. TP-Link or Huawei) generate a QR code with network details. Scan it with your phone's camera, and the connection will occur automatically.
• 🤝 Guest network. If the main network is secured but the guest network is open, connect to it (usually its name ends in _Guest).

⚠️ Attention: Connecting to someone else's network without the owner's permission may be considered a violation of the law (Article 272 of the Russian Criminal Code, "Unauthorized access to computer information"). Even if the network is not password-protected, its use without the administrator's consent is prohibited.

If you are a network administrator and want to make it easier for guests to connect, set up guest access in the router:

1. Go to the router's web interface (usually at 192.168.1.1 or 192.168.0.1).
2. Find the section Guest network (or Guest Network).
3. Enable the guest network, give it a name (for example, MyWiFi_Guest) and set a simple password or leave it open.
4. Limit speed and access to local devices for security.

Connection issues after phone update

After the update Android or iOS The phone may "forget" networks or fail to connect to them. Common causes:

• 🔄 Reset network settings. The update may have reset saved passwords.
• 🛠️ Change in security protocols. For example, Android 13+ gives preference by default WPA3, which may not be supported by older routers.
• 📵 Conflict with VPN or firewall. Some applications (eg. AdGuard or 1.1.1.1) block connections.

Solutions:

1. Restart your phone and router.
2. Forget the network on your phone (tap on it in Wi-Fi settings → Delete or Forget) and reconnect.
3. Check your VPN settings: disable it or add the network to the exceptions.
4. If the problem occurs after the update iOS, try resetting network settings: Settings → General → Transfer or reset → Reset network settings.

💡 Helpful tip: On Android can be turned on developer mode and forcefully change the Wi-Fi settings. To do this:

1. Go to Settings → About phone → Software version and press 7 times Build number.
2. Return to Settings → System → Developer Options.
3. Find the option Aggressive Wi-Fi switching or Always look for networks and turn it on.

Security: How to Protect Your Wi-Fi from Hacking

If your Wi-Fi is hacked, attackers can not only use your internet but also intercept traffic, access local devices (printers, cameras), or distribute malware. To prevent this:

• 🔒 Use WPA3-PSK. This is the most secure encryption protocol available today. If your router doesn't support it, WPA3, select WPA2-PSK (but not WEP or WPA!).
• 🔑 Complex password. It must contain at least 12 characters, including uppercase letters, numbers and special characters (e.g. K7#pL9!mQ2$v). Do not use personal information (dates of birth, names).
• 🔄 Update your router firmware regularly. Vulnerabilities in older versions of software make it possible to hack a network in minutes.
• 🚫 Disable WPS and UPnP. These features are convenient, but not secure.
• 📡 Hide the SSID. This won't protect you from professional hackers, but it will reduce the number of accidental connections.

⚠️ Attention: If you notice that your internet speed has suddenly dropped, and unknown devices have appeared in the list of connected devices (in the router's web interface), your network has been hacked. Immediately change your password and scan your router for malware (for example, using a utility). Fing).

For additional protection:

• Set up MAC address filtering (allow connection only to your devices).
• Turn on guest network for friends, it is isolated from the main one.
• Use VPN on a router (For example, NordVPN or Surfshark) to encrypt all traffic.

FAQ: Frequently asked questions about connecting to Wi-Fi

Is it possible to connect to Wi-Fi without a password if you know the router's MAC address?

No, knowing the router's MAC address doesn't help bypass the password. The MAC address is only needed for device filtering (if enabled in the router settings). Connecting still requires a password or a network security vulnerability (such as an outdated protocol). WEP).

Why does my phone connect to Wi-Fi, but websites won't open?

There are several reasons:

• 🌐 The provider is having problems. Check if the Internet works on other devices.
