For your convenience, we've divided the material by brand and added a feature compatibility table. And if you need to not just turn on Wi-Fi, but also share internet from your phone, go to relevant section.

Method 1: Quickly enable via the notification panel

The most obvious and universal method is to use notification curtainIt works on 99% of devices, regardless of manufacturer or firmware version. Here's how to do it:

1. Swipe top down on the screen to open the notification panel.
2. If you see a Wi-Fi icon (usually stylized as waves or sector), tap it once. If the panel isn't there, swipe it again to expand the full curtain.
3. On some phones (eg. Xiaomi or OPPO) may be required hold the icon 1-2 seconds to go to network settings.

⚠️ Attention: On devices with Android Go Edition (For example, Nokia 1.4 or Samsung Galaxy A03 Core) The notification panel may look different. If the Wi-Fi icon is missing, check the "Quick Settings" section in system settings.

If nothing happens after clicking the icon, the reasons may be as follows:

• 🔋 Airplane mode activated (disables all wireless modules).
• 📵 Energy saving Disables background processes, including Wi-Fi.
• 🔄 Module failure — a phone reboot is required.
• 🛠️ Firmware corruption (rare, but occurs after unsuccessful updates).

Method 2: Via Android settings (step-by-step instructions for different brands)

If quick access doesn't work, you can enable Wi-Fi through the main settings. The menu interface varies depending on the manufacturer, so we've compiled instructions for popular brands.

For Samsung (One UI 5.0/6.0)

1. Open the app Settings (icon ⚙️).
2. Go to the section Connections → Wi-Fi.
3. Move the slider to the right or click on the "Wi-Fi" text.

3. Click on your network name and enter the password.

💡 Helpful tip: On some phones (eg. Huawei) Wi-Fi may be hidden in the section Mobile networkIf you don't find the icon right away, use the settings search (magnifying glass in the upper right corner).

Why do manufacturers change the location of Wi-Fi settings?

Each brand uses its own skin on top of Android (One UI, MIUI, ColorOS, etc.), which modifies the standard interface. This is due to marketing strategies, patent restrictions, and attempts to differentiate themselves from competitors. For example, Xiaomi integrates additional features (such as "Wi-Fi Assistant") directly into the main settings, while Samsung places them in a separate "Connections" menu.

Method 3: Voice assistant (Google Assistant or Bixby)

If you're too lazy to fiddle with settings, you can turn on Wi-Fi with your voice. This method is especially convenient when your hands are full or the screen is locked. Here's how it works:
