If on your Galaxy S23, A54 If the Wi-Fi button on my iPhone or other model doesn't respond, the gray slider doesn't move, or the network is constantly "saving" without connecting, the problem could be a software glitch or a hardware issue. In 80% of cases, you can fix the problem yourself without visiting a service center.

This article will help you understand why The Wi-Fi module does not turn on on phones Samsung and what to do depending on the symptoms: from basic checks to hidden engineering settings. We'll look at universal solutions for all models. Android 10-14, as well as specific features for flagship series Galaxy S And Galaxy ZIf the problem persists after reading this, you'll know for sure whether it's worth taking your phone in for repair or whether a soft reset will suffice.

Important: Before starting diagnostics, make sure the problem is with your phone. Try connecting to the same network from another device (laptop, tablet). If Wi-Fi works on other devices, proceed to the instructions below. If not, check the router: reboot it, make sure the Wi-Fi indicator is green/blue (not red), and that "silent mode" is not activated (WPS/Wi-Fi button on the router body).

1. Basic checks: what to do before resetting

Start with the simple steps—they take less than a minute but often solve the problem. Many users skip this step and move straight to complex steps, wasting time.

Check the physical Wi-Fi switch (if any). On some models Samsung (For example, Galaxy XCover Pro) There's a hardware button on the side panel that could accidentally lock the module. Make sure it's not in the "Off" position.

Then reboot your phone Manually. Long press the power button (10-15 seconds) until the shutdown menu appears, then select "Restart." This clears the RAM and resets temporary Wi-Fi driver errors.

• 🔄 Airplane mode: Turn it on for 30 seconds, then turn it off. Sometimes this "wakes up" the wireless module.
• 📶 Automatic connection: go to Settings → Connections → Wi-Fi and disable the "Auto-connect to open networks" option (it may conflict with manual control).
• 🔋 Battery chargeIf the battery level is below 15%, some models limit the operation of power-hungry modules, including Wi-Fi. Connect the charger.

Critical detail: on phones with One UI 5.0+ (Android 13/14) After updating, "background data protection" may be activated to save battery. This prevents network scanning in sleep mode. To check this, go to Settings → Device Care → Battery → Sleep Mode and disable the "Restrict background activity" option.

2. Resetting network settings: when it helps

If the basic methods don't work, the next step is reset network settingsThis will delete all saved Wi-Fi networks, passwords, Bluetooth settings, and mobile data (APN) data, but will not affect personal files or apps.

Instructions for One UI (relevant for Galaxy S20 and newer):

1. Open Settings → General → Reset.
2. Select "Reset network settings".
3. Confirm the action (you may be asked to enter a PIN or pattern).
4. After rebooting, try turning on Wi-Fi again.

On older models (Galaxy J, Galaxy A 2018 and earlier) the path may differ: Settings → Device Maintenance → Reset → Reset Network Settings.

⚠️ Attention: If you use corporate Wi-Fi with security certificates (for example, in an office or university), after a reset, you may need to reinstall the certificates through the company's application or the IT department.

After the reset, your phone may not detect networks that previously connected automatically. This is normal—just select the network manually and re-enter the password. If the issue persists, proceed to the next section.

⚠️ Attention: On some models (Galaxy S20 FE, Galaxy A71) after reset through Recovery reactivation may be required after Samsung AccountMake sure you remember your login and password!

If resetting doesn't help, the problem is definitely hardware-related. In this case:
