How to quickly connect Wi-Fi to another phone: all the methods 2026

Sharing Wi-Fi from one smartphone to another is a challenge faced by every second user, according to research. Statista By 2023, 68% of smartphone owners had shared their home network password with guests or family members at least once. But not everyone knows that manually entering complex character combinations is far from the most convenient method. Modern Android And iOS offer at least 5 alternative methods, from scanning QR code before automatic synchronization via the cloud.

In this article, we'll cover all the current methods for connecting a second phone to Wi-Fi—from standard to lesser-known. You'll learn how to share networks between iPhone And Android, what limitations apply to different OS versions, and how to avoid common errors (for example, when the network connects, but the internet doesn't work). We'll pay special attention Bluetooth method that works even without access to a router — this will be a lifesaver in a hotel or cafe where the password is issued only for one device.

1. Connection via QR code (the fastest way)

Method with QR code appeared in Android 10 And iOS 11, but remains little used, despite being the most reliable and error-free data transfer method. The main advantage: no need to manually enter a long password or network SSID. Simply scan the code from the first phone's screen.

How it works in practice:

• 📱 On Android: open Settings → Wi-Fi, tap on the connected network → select "Share" or "QR code". On some firmware (for example, MIUI or One UI) the option is hidden behind the "More" button (three dots).
• 🍎 On iPhone: go to Settings → Wi-Fi, tap the blue "i" icon next to the network name → "Share password" (if the option is inactive, check if Bluetooth is turned on).
• 🔍 On the second phone: open the camera or a dedicated QR scanning app (e.g. Google Lens), point to the code and confirm the connection.

Important: If the QR code is not readable, try:

• 🔦 Increase the brightness of the first phone's screen.
• 📱 Make sure that Wi-Fi is turned on on the second device (sometimes the scanner does not turn it on automatically).
• 🔄 Restart both devices - this resets the network settings cache.

⚠️ Attention: On iPhone With iOS 16 and newer, a network QR code can only be generated if the router supports the standard WPA3For networks with WPA2 we will have to use alternative methods.

2. Automatic password transfer (only for Apple and new Android)

Function Wi-Fi Password Sharing on iPhone And Nearby Share on Android allow you to share network access without manual input—just bring the phones close together. This method only works between devices within the same ecosystem (e.g., iPhone → iPhone or Samsung → Google Pixel).

Instructions for iOS:

1. Make sure that on both iPhone included Bluetooth And Wi-Fi, and also that they are added to your Apple ID (in Family Sharing or as trusted devices).
2. On the second phone, select the network from the Wi-Fi list.
3. On the first iPhone A notification will appear saying "Share Wi-Fi password" - confirm the action.

For Android (starting from Android 12):

• 🤝 Turn it on Nearby Share in the settings (Google → Devices and Sharing).
• 📶 On the second phone, select the Wi-Fi network you want to connect to.
• 🔑 On the first device, a request to transfer the password will appear - confirm it.

3. Manual connection: where to find the Wi-Fi password

If automatic methods do not work (for example, you have an old Android 8 (or a router with non-standard settings), you'll have to enter the password manually. But where can you find it if you don't remember it? There are three reliable methods:

Method 1: Look on the router

• 📋 On most routers (TP-Link, ASUS, Keenetic) the password is indicated on the sticker at the bottom of the device in the field Wi-Fi Password or Network Key.
• 🔧 If there is no sticker, try standard combinations: admin, 12345678 or password (works on 15% of routers according to data Kaspersky).

Method 2: Find out the password from the connected phone

• 📱 On Android (with root rights): use the application WiFi Password Viewer (requires bootloader unlocking).
• 🍎 On iPhone: without jailbreak you can't see the password, but you can connect to the router through USB and use iTunes to export settings (instructions below).

Method 3: Log in to the router's admin panel

1. Open your browser and type in the address bar 192.168.1.1 or 192.168.0.1 (For Keenetic — my.keenetic.net).
2. Enter your login and password (usually admin/admin or admin/password).
3. Go to the section Wi-Fi or Wireless network - there will be a field there Password or Key.

What should I do if I can't access my router settings?

If the standard IP addresses (192.168.1.1 or 192.168.0.1) do not open, try:

1. Check the connection to the router via cable (Wi-Fi may be disabled).

2. Use the command ipconfig V Command line (Windows) or ifconfig V Terminal (Mac/Linux) to find the default gateway.

3. Reset the router using the button Reset (hold for 10 seconds) - this will restore factory settings, including the default password.

4. Connecting via Bluetooth (if there is no access to the router)

This method is useful in situations where you can't change your router settings (for example, in a hotel or on a plane), but you already have one phone with Wi-Fi access. The idea is that the first phone distributes Internet second through Bluetooth, rather than directly connecting it to the network.

Step-by-step instructions:

Turn on Bluetooth on both phones|Pair the devices (on one, tap “Add new device”)|On the first phone, activate “Tethering” (Settings → Connections → Tethering & portable hotspot)|Select "Bluetooth Modem"|On the second phone, confirm the Internet connection-->

Advantages of the method:

• 🌍 Works even if the router blocks new connections (for example, by MAC address).
• 🔒 Doesn't require knowing your Wi-Fi password.
• 📶 Suitable for devices without a Wi-Fi module (for example, some tablets).

Flaws:

• 🐢 Internet speed will be lower (Bluetooth 4.0 is limited to ~25 Mbps).
• 🔋 The battery drains quickly on both phones.
• 📵 Not all mobile operators allow internet tethering (check your plan).

⚠️ Attention: On iPhone Internet sharing via Bluetooth is only available if you have a plan that supports it. tetheringSome operators (eg. Tele2 or Yota) block this function on basic tariffs.

5. Using NFC (for modern Android smartphones)

NFC (Near Field Communication) is a technology for wireless data transmission at a distance of up to 10 cm. It is supported by most flagship smartphones (Samsung Galaxy S22+, Google Pixel 7, Xiaomi 13), but is rarely used for Wi-Fi sharing due to low user awareness.

How to connect via NFC:

1. Make sure NFC is turned on on both phones (Settings → Connections → NFC).
2. On the first phone, open the list of Wi-Fi networks and tap on the connected network.
3. Select the "Share" or "NFC" option (on some firmware it is called "Touch to Share").
4. Place the back cover of the second phone next to the NFC chip of the first one (usually located at the top of the case).
5. Confirm data transfer on both devices.

Where is the NFC chip located in popular models:

• 📱 Samsung Galaxy: top of the back panel (near the camera).
• 📱 Google Pixel: in the center of the back cover.
• 📱 Xiaomi/Redmi: in the upper left corner (under the logo).
• 📱 iPhone: There is NFC, but does not support Wi-Fi sharing (Apple Pay only).

6. Sharing Wi-Fi from your phone (if you don't have a router)

If you need to connect a second phone to the Internet, but there is no router nearby, you can use the first smartphone as access pointThis method is universal and works on all modern devices, but has traffic and speed limitations.

How to set up an access point:

• 📶 On Android: Settings → Connections → Tethering & portable hotspot → Mobile hotspotSet the network name and password.
• 🍎 On iPhone: Settings → Tethering (or "Personal Hotspot"). Turn on Wi-Fi or Bluetooth sharing.

Important nuances:

• 📊 Monitor your traffic consumption: some operators consider internet sharing as a separate service (for example, MTS in the "Everything for our own" tariff).
• 🔋 Turn off the hotspot when you don't need it - this saves battery life.
• 🔒 Use a complex password (at least 8 characters with numbers and letters) to prevent unauthorized access to your network.

7. Common mistakes and their solutions

Even if you follow the instructions correctly, your Wi-Fi connection may not work. Here are the most common issues and how to fix them:

Problem 1: The network connects, but the internet doesn't work.

• 🔄 Reboot your router (unplug it from the power outlet for 30 seconds).
• 📵 Check if the "Data Saver" mode is enabled on your phone (Settings → Connections → Data Saver).
• 🌐 Make sure your router doesn't have parental controls or MAC address blocking configured.

Problem 2: Unable to share password via QR or Bluetooth

• 📱 Update the OS on both phones to the latest version.
• 🔧 On Android Check if permissions for the Settings app are disabled (Settings → Applications → Settings → Permissions).
• 🍎 On iPhone Make sure the "Share Password" feature is enabled in Settings → Apple ID → iCloud → Keys.

Problem 3: My phone's hotspot keeps disconnecting.

• 🔋 Connect your phone to a charger - many models turn off the data connection when the battery level is low.
• 📴 Check if the device is overheating (at temperatures above 45°C, dispensing may be blocked).
• 📶 If you use mobile internet, make sure you have a good signal (1-2 antenna divisions are not enough).

⚠️ Attention: On some firmware versions Android (For example, ColorOS on Oppo/Realme) The hotspot automatically turns off after 5 minutes of inactivity. To avoid this, enable "Always on" mode in the modem settings.

FAQ: Answers to Frequently Asked Questions

Is it possible to connect an iPhone to Wi-Fi if only the Android phone knows the password?

Yes, but not in all ways. The most reliable options are:

1. Generate QR code on Android (through Settings → Wi-Fi → Share) and scan it with a camera iPhone.
2. Find out the password manually Android (with root rights or through a router) and enter it on iPhone.
3. Use Bluetooth modem: share internet with Android on iPhone through Settings → Tethering & portable hotspot → Bluetooth tethering.

Automatic password transfer (both between iPhone) does not work between different ecosystems.

Why do I get the error "Failed to connect to network" when connecting via QR code?

This error occurs in 3 cases:

• 🔄 The router has changed the password, but the phone has not yet updated the data (reconnect to the network on the first device).
• 📵 The network operates in the range 5 GHz, and the second phone only supports 2.4 GHz (check in your router settings).
• 🔒 It is used on the network hidden SSID (the network name is not broadcast). In this case, you will have to enter the data manually.

How to connect an old phone (Android 6.0) to Wi-Fi if it doesn't support QR and NFC?

For devices on Android 6.0–9.0 There are 3 methods available:

1. Manual password entry: find it out from another phone or router (instructions in section 3).
2. Distribution from a new phone: Turn on the hotspot on your modern smartphone and connect to it from your old one.
3. Sharing apps: use WiFi Key Share or Send Anywhere to transfer the password via a file.

On Android 6.0 and below, resetting the router to factory settings may also help - this will return the default password (indicated on the sticker).

Is it possible to connect a phone to Wi-Fi without a password?

Technically yes, but with some caveats:

• 🔓 If the network open (without password), the phone will connect automatically.
• 📡 If the router supports WPS, you can connect by pressing the WPS button on the router and selecting the appropriate option on your phone (in Settings → Wi-Fi → Advanced).
• 🚫 Hacking into other people's networks with a password is illegal (in the Russian Federation, it is punishable under Article 272 of the Criminal Code, "Unauthorized access to computer information").

Why doesn't the second phone connect to Wi-Fi after transferring the password via Bluetooth?

This is a common problem when sharing internet via Bluetooth. Causes and solutions:

• 📶 Weak Bluetooth signal: Bring the phones closer to each other (maximum 10 meters).
• 🔋 Energy saving: Disable battery saving mode on both devices.
• 📴 IP address conflict: Restart both phones or manually set static IPs in Wi-Fi settings.
• 🔄 Operator error: Some mobile networks block tethering (check in your operator's personal account).

If nothing helps, try distributing Wi-Fi via USB cable (on Android (This is called a "USB modem").
