You are trying to connect to the internet, but the button Wi-Fi The menu on your phone doesn't respond to taps, is grayed out, or isn't even in the menu? This problem occurs on both Android-devices (Samsung, Xiaomi, Huawei), and on iPhone — and there could be a dozen reasons for it, from a simple operating system glitch to serious hardware malfunctions.
In this article we will look at all the possible scenarios why Wi-Fi won't turn on on my phone, - from the obvious (for example, airplane mode) to hidden problems (antenna damage or firmware conflicts). For each case, we'll provide step-by-step instructions for diagnosing and troubleshooting. And if the problem turns out to be hardware-related, we'll show you how to minimize repair costs.
First, check the basics: is it disabled? power saving mode (It often blocks background processes, including Wi-Fi), whether mobile data restrictions are in place, and whether the device is overheating. If all of this is OK, read on.
1. Software failures: reboot and reset network settings
In 60% of cases, the Wi-Fi button becomes inactive due to temporary operating system glitches. This can happen after a firmware update, installing a new app, or even simply because the phone is overheating. The first thing to do is... force restart the device.
On Android:
- 🔄 Press and hold the power button for 10-15 seconds until the screen goes dark and the phone begins to reboot.
- 📱 If the screen is not responding, try the combination
Power + Volume Down(on some models Samsung And Xiaomi). - 🔌 If the phone is discharged to 0%, connect it to a charger for 10-15 minutes, then restart it again.
On iPhone:
- 🍎 For models with
Face ID(iPhone X and later): Quickly tapIncrease volume→Decrease the volume→ pressSide buttonuntil the Apple logo appears. - 🔘 For iPhone 8/SE (2nd generation): press and hold
Side button + Volume downfor 10 seconds. - 🏠 For iPhone 7: Press and hold
Side button + Volume down.
If rebooting doesn't help, the next step is reset network settingsThis procedure deletes all saved Wi-Fi networks, passwords, VPN settings, and APNs, but does not affect personal data (photos, contacts, messages).
Instructions for Android:

⚠️ Attention: On some models Xiaomi And Realme A network reset may also delete Bluetooth and mobile data settings. Before the procedure, save important APNs (for example, for MTS or Beeline) if you are using non-standard settings.
2. Flight mode, power saving and other system restrictions
Often the Wi-Fi button becomes inactive due to the enabled systemic limitationsLet's check the most common ones:
- ✈️ Flight mode (airplane mode). Even if it's disabled in the notification shade, sometimes a software bug can trigger and block Wi-Fi at the system level. Check:
- Open
Settings → Connections → Airplane Mode(orSettings → Network & Internet → Airplane Modeon Android). - Make sure the switch is off.
- If the mode was enabled, restart your phone.
- Open
Settings → Battery → Power saving mode.- On Android:
Settings → Digital Wellbeing & Parental Controls. - On iPhone:
Settings → Screen Time → Content & Privacy Restrictions.
Another possible reason is - conflict with VPN or proxySome VPN applications (for example, NordVPN or 1.1.1.1) may block your Wi-Fi connection if the server is unavailable. Try:
- Disable the VPN in the notification shade or in the app settings.
- Delete VPN profile in
Settings → Connections → Other networks → VPN(Android) orSettings → General → VPN(iPhone). - Reset network settings (see previous section).
3. Firmware issues: updates, resets, and custom OSes
If the Wi-Fi button becomes inactive after firmware updates, the cause may be a bug in the new OS version. This is especially true for Android-devices where manufacturers sometimes release unreleased updates. Here's what to do:
- 🔍 Check your firmware version. Go to
Settings → About phone → Software version. Remember the build number (for example,MIUI 14.0.5orOne UI 5.1). - 🌐 Look for information about the bug. Enter a query like this into Google:Phone model + firmware version + Wi-Fi is not working." Often on forums (for example, 4PDA or XDA Developers) there are already solutions.
- 🔄 Roll back to the previous version. If the bug is widespread, the manufacturer may release a patch. If not, you'll have to roll back. Samsung This can be done through Smart Switch, For Xiaomi - through Mi Flash Tool.
On iPhone Wi-Fi issues after updating iOS are less common, but still possible. In this case:
- Check if there is a new update available
Settings → General → Software Update. - If there are no updates, please do reset all settings (no data!) in
Settings → General → Transfer or reset iPhone → Reset → Reset all settings. - If this doesn't help, restore your iPhone via iTunes (on Windows) or Finder (on Mac).
⚠️ Attention: If you installed custom firmware (For example, LineageOS or Pixel Experience), the issue may be a kernel incompatibility with the Wi-Fi module. In this case, you'll need to reflash the device to the official or other custom firmware with a working driver.
| Manufacturer | Common Wi-Fi Problems | Solution |
|---|---|---|
| Samsung | After updating One UI, Wi-Fi turns off by itself or does not turn on. | Network reset or rollback via Smart Switch |
| Xiaomi | Wi-Fi doesn't work after flashing via Fastboot | Reflash via Mi Flash with data wipe |
| Huawei | Wi-Fi won't turn on after factory reset | Install the latest version of EMUI via HiSuite |
| iPhone | Wi-Fi is inactive after iOS update | Reset all settings or restore via iTunes |
4. Hardware faults: antenna, Wi-Fi module and contacts
If software methods do not help, the problem may be hardwareThe most common failures are:
- 📡 Wi-Fi antenna. It can come off if the phone is dropped or after the case is disassembled. Symptoms: Wi-Fi doesn't turn on, but Bluetooth works (they share the same antenna on many models).
- 🔌 Wi-Fi module. The chip responsible for wireless communication can burn out due to overheating or a short circuit. Symptoms: the Wi-Fi button is gray, and Bluetooth is also inoperative.
- 🔗 Contacts or cable. If the phone was dropped or got wet, the contacts between the motherboard and the Wi-Fi module could become oxidized.
A critical sign of hardware failure: if the Wi-Fi section in the phone settings is completely missing (not just an inactive button, but a complete absence of the menu item). In this case, repairs are unavoidable.
How to check:
- Try turning it on modem mode (Wi-Fi sharing). If your phone can't share the internet, but the mobile network works, the problem is definitely with the Wi-Fi module.
- Connect your phone to your computer and check if it is detected as a network device (for example, via
ipconfigin the Windows command line). - If possible, test a different SIM card—sometimes mobile network problems can be disguised as Wi-Fi issues.
Repair cost:
- Wi-Fi antenna replacement: from 800 to 2,500 rubles (depending on the model).
- Wi-Fi module replacement: from 1,500 to 5,000 rubles.
- Contact cleaning: from 500 to 1,500 rubles.
⚠️ Attention: If your phone gets wet, don't turn it on until it's completely dry (at least 24 hours in rice or silica gel). Trying to turn on a device with moisture inside can cause a short circuit and damage not only the Wi-Fi but also other components.
How to test a Wi-Fi antenna yourself?
To do this, you'll need to disassemble the phone and test the antenna contacts with a multimeter. On most models, the antenna is located under the back cover, near the top of the circuit board. If the resistance approaches infinity, the antenna is broken. Be careful: disassembling the phone yourself will void the warranty!
5. App conflicts: who's blocking Wi-Fi?
Some applications may block Wi-Fi for various reasons:
- 🛡️ Antiviruses and firewalls. Programs like Kaspersky, Avast or 360 Security sometimes block network connections if they consider them unsafe.
- 🔒 Parental control apps. For example, Google Family Link or Qustodio may restrict Wi-Fi access during certain hours.
- 🎮 Game accelerators. Programs like Game Turbo (on Xiaomi) or Game Launcher (on Samsung) sometimes turn off Wi-Fi to save battery.
- 🔄 Optimizers and cleaners. Clean Master, CCleaner and similar utilities can "optimize" system processes, including the Wi-Fi module.
How to find the culprit:
- Start your phone in safe mode:
- On Android: Press and hold the power button → long tap on “Power off” → “Safe mode”.
- On iPhone: There is no safe mode, but you can remove suspicious applications.
If you don't want to delete apps, check their settings:
- In your antivirus software, disable the "Network Protection" or "Firewall" function.
- In Games and Accelerators, find the "Power Saving" section and remove Wi-Fi from the list of optimized processes.
- Check parental controls for time or network type restrictions.

6. Router problems: why the phone can't see the network
Sometimes the problem is not with the phone, but with routerIf the Wi-Fi button on your phone is active, but networks are not displayed or cannot be connected, check:
- 🔌 The router is turned on and working. Check if the power and Wi-Fi indicators are lit. If not, reboot the router (unplug it from the power outlet for 30 seconds).
- 📶 The network is hidden. If "Hide SSID" is enabled in your router settings, your phone won't see the network. Connect manually by entering the network name and password.
- 🔒 MAC address filtering. If MAC address binding is enabled in your router, your phone may be blacklisted. Check your settings in
192.168.0.1or192.168.1.1(logins and passwords are usuallyadmin/admin). - 🔄 Incompatible Wi-Fi standard. If the router only works in the mode
802.11n(5 GHz), and the phone only supports802.11b/g(2.4 GHz), connection will be impossible. Change the mode in the router settings.
How to check if the router is at fault:
- Try connecting to Wi-Fi from another device (laptop, tablet).
- If other devices connect, the problem is with the phone.
- If they don’t connect, reset the router to factory settings (button
Reseton the back panel).
If the router issues an IP address, but the Internet does not work:
- Check your DNS settings. Try manually entering them.
8.8.8.8(Google) or1.1.1.1(Cloudflare). - Disable IPv6 in your router settings if it is enabled.
- Check if your provider blocks your device by MAC address (relevant for some tariffs) Rostelecom or Beeline).
