How to connect to Wi-Fi on your phone: instructions for Android and iOS with solutions to common errors

Connecting to Wi-Fi on your smartphone seems like a simple task—until you encounter errors like “Unable to connect” or “Saved, but no internet access.” Even if you use wireless networks every day, the connection algorithms on Android 14 And iOS 17 There are nuances that few people know about. For example, why can a phone "see" a network but not connect to it after updating the router firmware? Or how do you manually add a hidden network without a QR code scanner?

In this article, we will cover not only the basic connection steps, but also Solutions to 7 common problems, which users contact their providers' support services about. You'll learn how to bypass public network restrictions and why WPA3 can block older devices, and what to do if the phone "forgets" the password after a reboot. And for owners Samsung Galaxy And iPhone 15 We have added individual blocks taking into account their brand features.

1. Basic Wi-Fi Connection: Step-by-Step Instructions

Let's start with a universal algorithm that works on 90% of modern smartphones. Important: if your phone was released before 2018, some menu items may differ—we'll warn you about this separately.

On Android (including Xiaomi, Realme, Google Pixel):

  1. Open Settings → Wi-Fi (or Network and Internet → Wi-Fi on pure Android).
  2. Activate the slider Wi-Fi (if it is turned off).
  3. Select the desired network from the list of available networks. If the network is not listed, click Add a network manually.
  4. Enter your password (case sensitive!) and click Connect.

On iPhone (iOS 15–17):

  1. Go to Settings → Wi-Fi.
  2. Make sure the slider is Wi-Fi green.
  3. Tap on the network name, enter the password and confirm.

⚠️ Attention: If after connecting an exclamation mark appears next to the network name (!), this means that the phone is connected to the router, but it is not distributing the Internet. The reasons and solutions are in Section 5.

📊 What type of Wi-Fi do you use at home?
Normal (2.4 GHz)
Dual-band (2.4+5 GHz)
Mesh system
Mobile hotspot

2. Connecting to a hidden network (without broadcasting SSID)

Hidden networks do not broadcast their name (SSID), so they cannot be selected from a standard list. This is often used in offices or home networks to "increase security" (although in practice, hidden SSID easily detected by scanners).

To connect to such a network:

  • 📱 On Android: Settings → Wi-Fi → Add networkIn the field Network name (SSID) Enter the exact name (case sensitive!), select the security type (WPA2-PSK or WPA3) and enter the password.
  • 🍎 On iPhone: Settings → Wi-Fi → Other networkFill in the fields Name And Security, then save.

Critical detail: If the network name contains spaces or special characters (eg. My_Wi-Fi@2026), enter them exactly, otherwise the connection will fail.

Check the exact network name (SSID) with your administrator|Check the case of the letters in the name and password|Make sure the router is turned on and distributing Wi-Fi|Disable your VPN (it may be blocking the connection)-->

3. Connection Features on Samsung Galaxy and iPhone

Manufacturers often modify the default Android settings. For example, on Samsung Galaxy S23 and newer there is a function Smart Network Switch, which automatically switches the phone from Wi-Fi to mobile data if the signal is weak. This can create the illusion of a "dropped connection."

How to disable automatic switching on Samsung:

  1. Go to Settings → Connections → Wi-Fi.
  2. Click on the three dots () in the upper right corner and select Advanced settings.
  3. Disable the option Auto-connection to open networks And Switch to mobile data.

On iPhone a similar function is called Wi-Fi AssistTo deactivate it:

  1. Settings → Cellular (or Mobile data).
  2. Scroll down to the block Wi-Fi Assist and move the slider to the left.

⚠️ Attention: On iPhone 15 Pro With iOS 17.2+ an option appeared Private Wi-Fi Address (private MAC address). Disabling it may be necessary to connect to corporate networks with MAC filtering.

What is Private Wi-Fi Address on iPhone?

This feature automatically changes your device's MAC address when connecting to different networks, making it more difficult to track. However, some routers (especially in hotels or offices) block devices with frequently changing MAC addresses. If you're having trouble connecting, try disabling this option in your network settings (tap the "i" symbol next to the Wi-Fi name).

4. Troubleshooting connection issues

If your phone won't connect to Wi-Fi, the reasons can be divided into 3 categories:

Type of problem Signs Solution
Incorrect password "Incorrect password" or "Authentication failed" message Check the case, symbols, and spaces. Try entering the password on a different device.
MAC restriction The connection is stuck at the IP acquisition stage. Add your phone's MAC address to the router's whitelist or disable filtering.
WPA3 incompatibility The phone does not see the network WPA3 or it connects, but without internet Enable the mode in your router settings. WPA2/WPA3 Mixed.
IP conflict Message "IP address not received" Reboot your router or assign a static IP manually.

For diagnostics on Android:

  1. Tap and hold the network name in the Wi-Fi list and select Delete network (or Forget).
  2. Restart your phone and router.
  3. Try connecting again.

On iPhone:

  1. Tap on the symbol i next to the network and select Forget this network.
  2. Turn on/off the mode Airplane mode.
  3. Please try connecting again.

5. Connecting to public networks (in cafes, airports, hotels)

Public Wi-Fi often requires additional authentication through a browser (called captive portal). Connection algorithm:

  1. Connect to the network (the password is usually indicated on the counter or on the receipt).
  2. Open any browser (Chrome, Safari). The system will automatically redirect you to the login page.
  3. Enter your details (phone number, room number, login/password from your provider).
  4. Please confirm the terms of use (check mark) I Accept (required!).

⚠️ Attention: Some public networks are blocked VPN And TorIf the internet doesn't work after authentication, disable the VPN in your phone settings.

List of typical mistakes in hotels/airports:

  • 🔄 Cyclic redirect: The login page keeps opening. Solution: Clear your browser cookies or try a different one (such as Firefox).
  • Time limit: Access is only granted for 1–2 hours. Solution: Reconnect or check with the administrator about the rules.
  • 📵 Blocking messengers: In some countries (like the UAE), WhatsApp and Skype are blocked even on Wi-Fi. Solution: Use a VPN. to network connections.

6. Configuring the router for a stable connection

If Wi-Fi issues occur on multiple devices, the router is most likely the cause. Check the following settings (instructions for TP-Link, ASUS, Keenetic):

Optimal settings for a home network:

  • 📶 Opening hours: 802.11n/ac/ax (don't use outdated 802.11b/g).
  • 🔒 Safety: WPA2-PSK AES or WPA2/WPA3 Mixed (Not WEP!).
  • 📡 Channel: Auto (or manually select the least loaded one in the app) Wi-Fi Analyzer).
  • 🔄 DHCP: Enabled (if disabled, assign IP manually on the phone).

To change settings:

  1. Connect to the router via cable or current Wi-Fi.
  2. Enter in your browser 192.168.1.1 or 192.168.0.1 (the address is indicated on the router sticker).
  3. Log in (standard login/password: admin/admin or admin/password).
  4. Go to the section Wireless or Wi-Fi and save the changes.

7. Alternative connection methods

If the standard connection doesn't work, try these methods:

Method 1: QR code (for Android 10+ and iOS 11+)

  • On another device (already connected to Wi-Fi), generate a QR code for the network. For example, in iPhone: Settings → Wi-Fi → Tap on network → QR icon.
  • Scan the code with your phone's camera - it will connect automatically.

Method 2: WPS (Android only)

  • Click the button WPS on the router (usually on the back panel).
  • On the phone: Settings → Wi-Fi → Advanced → WPS Connection.
  • ⚠️ Attention: WPS is vulnerable to hacking - disable the feature in your router after connecting.

Method 3: USB tethering (for PC)

  • Connect your phone to your computer via USB.
  • On the phone: Settings → Network & Internet → Hotspot & Tethering → USB Tethering.
  • On your PC, select connection via USB adapter.
