Your Samsung Galaxy A10 Suddenly stopped connecting to Wi-Fi, and the network power button doesn't respond to presses? This problem is familiar to many owners of this budget smartphone, released in In 2019The causes may lie in both software glitches and hardware malfunctions—from a simple module freeze to physical damage to the antenna.

Don't rush to take your phone in for repair—in 70% of cases, the problem can be fixed yourself in 10-15 minutes. Let's start with the easiest part!

1. Check basic settings: airplane mode, power saving, and geofencing

Before digging deeper, make sure the problem isn't rooted in trivial settings. Samsung Galaxy A10 is known to sometimes "forget" airplane mode after rebooting, or spontaneously activate power saving mode by disabling background processes—including Wi-Fi.

Open the notification panel and check:

• ✈️ Airplane mode If the icon is highlighted, tap it to disable it. Even if the indicator is gray, try turning the mode on and off again (sometimes the smartphone glitches when displaying the status).

2.1. Forced reboot

Press the buttons Power + Volume Down for 10-15 seconds until the phone reboots. This will reset the Wi-Fi module's temporary data. If the network works after the reboot, but then disappears again after a while, the problem is a background process that is consuming the module's resources.

2.2. Resetting network settings

This method deletes all saved Wi-Fi networks, passwords, and Bluetooth settings, but does not affect personal data. Go to:

Settings → General Management → Reset → Reset Network Settings

• 📶 Damage to the Wi-Fi antenna — often occurs after drops or exposure to water. The antenna is located at the top of the phone (next to the camera).
• 🔌 Oxidation of Wi-Fi module contacts - due to overheating or high humidity.
• 🔧 Motherboard failure — especially after unsuccessful firmware updates or power surges.

You can check for hardware failure as follows:

1. Turn on diagnostic mode: dial in the phone dialer #0#. In the menu Hardware Test select Wi-FiIf the test shows an error, the problem is in the module.
2. Try connecting to Wi-Fi in Safe Mode (press and hold the power button → Turn off the power → hold Turn off before the offer to go to appears Safe mode). If Wi-Fi works in this mode, third-party software is to blame.

Some apps can block Wi-Fi, especially if they use a VPN, change network settings, or optimize battery life. Galaxy A10 Most often, conflicts are caused by:

• 🔒 VPN clients (For example, NordVPN, ProtonVPN) - can "lock" network interfaces.
• 🛡️ Antiviruses (Avast, Kaspersky) - sometimes block "suspicious" activity of the Wi-Fi module.
• 🔋 Battery optimizers (Greenify, AccuBattery) - disable background processes, including system ones.

To identify the culprit:

1. Go to Settings → Applications.
2. Sort apps by installation date (new ones are more likely to cause conflicts).
3. Disable suspicious programs one by one, checking the Wi-Fi connection.

If the problem goes away after disabling a specific app, uninstall it or add it to the battery optimization exceptions (Settings → Device Care → Battery → ⋮ → Settings → Background apps).

FAQ: Frequently asked questions about Wi-Fi on the Samsung Galaxy A10

🔍 Why does Wi-Fi turn on but not connect to the network?

This is a separate issue, unrelated to the inability to enable the module. Reasons:

• Incorrect network password (check the case of the characters!).
• The router is operating in the mode 802.11n (try switching to 802.11b/g in the router settings).
• IP address conflict (manually assign a static IP in the Wi-Fi settings on your phone).

📱 Can I fix Wi-Fi on my Galaxy A10 myself?

Yes, but only if the problem is software-related (resetting settings, updating software). For hardware repair, you'll need:

• Special screwdrivers (eg Torx T3/T4).
• Soldering (to replace the antenna or module).
• Tester for checking contacts.

Without experience, you risk damaging cables or chips. For beginners, it's best to limit yourself to clearing the cache or re-flashing the firmware.

🔄 What should I do if Wi-Fi still doesn't work after resetting my settings?

Try:

1. Install custom recovery (TWRP) and flash the Wi-Fi module separately.
2. Roll back the firmware to an older version (for example, from Android 11 to Android 10).
3. Use an external Wi-Fi adapter via USB OTG (not supported by all firmware).

If nothing helps, the problem is definitely hardware.

💰 How much does it cost to replace the Wi-Fi module on a Galaxy A10?

The cost depends on the region and type of service:

• Official service Samsung: 2,500–3,500 ₽ (with guarantee).
• Unofficial workshops: 1,500–2,500 ₽ (1–3 months warranty).
• Self-replacement: 500–1,000 ₽ (cost of the module per AliExpress).

Check with the technician to make sure the module is genuine—Chinese equivalents may only last a few months.

📡 Can I use the Galaxy A10 as a Wi-Fi router if its own Wi-Fi is broken?

Yes, but with some reservations:

• Through USB modem (works even without a Wi-Fi module).
• Through Bluetooth modem (slower, but stable).

Function Wi-Fi hotspot won't work because it depends on a working Wi-Fi module. An alternative is to buy an external USB Wi-Fi adapter that supports OTG (For example, TP-Link TL-WN725N), but you will need root and special software like USB Wi-Fi Tether.
