1. Check Wi-Fi Hardware Status

Wi-Fi toggle grayed out?
Is the Wi-Fi toggle switch in settings active or greyed out? If greyed out, it could mean the Wi-Fi chip is malfunctioning or disabled at a hardware level.


2. Verify Wi-Fi settings and permissions

Go to Settings > Apps > Show system apps > Wi-Fi Direct or Wi-Fi Services (if available).

Clear cache and data for Wi-Fi related services/apps.


3. Try Connecting via Wi-Fi Scanner Apps

Download a Wi-Fi scanner app (like WiFi Analyzer from the Play Store) and check if it can detect any networks.

If these apps don’t see any networks either, the phone's Wi-Fi radio might be faulty.


4. Inspect for Physical or Water Damage

Any recent drops, water exposure, or physical damage could cause Wi-Fi hardware failure.


5. Check for Software Updates

Go to Settings > Software update and ensure your phone has the latest system update installed.


6. Factory Reset (Last Resort)

If nothing works, a full factory reset can eliminate software corruption. Make sure to back up your data first.


7. Hardware Repair

If after a factory reset Wi-Fi still doesn’t detect networks or toggle on, the Wi-Fi module or antenna might be defective.

Consider visiting a Samsung service center or authorized repair shop.

Dear Samsung Member,

Greetings from Samsung Customer Support!

We regret to hear about your experience with our product. Please believe that this is not a usual occurrence.

Kindly perform the following steps to resolve your device wi-fi and hostport issues:

→ Check Settings: Do you get any error pop up, on connecting your device to a Wi-Fi network?
Note: Any prompt that says "Authentication Error" is related to an incorrect password. Please contact your Internet Service Provider for assistance regarding changing your Wi-Fi network password.

→Reset settings: Tap on Settings>General Management> Reset and then tap on Reset settings.

1) Switch off your Wi-Fi router at the wall and wait 2-3 minutes before turning it back on. Once the router has successfully connected to the internet again, try to connect to your network on your phone.

2) Some Wi-Fi routers support both 2.4GHz and 5GHz. Most Galaxy devices will switch between these channels automatically when required. For example, when you are closer to the router your device will switch to 5GHz and swap to 2.4GHz when further away.

3) Make sure there is no interference between the router and your phone. Concrete walls, fridges, and microwaves can all interrupt the Wi-Fi signal.

4) If possible, try and connect your device to a different Wi-Fi connection. If you can connect, you should contact your Wi-Fi provider for more assistance.

→ Kindly check and disable the Airplane/Flight Mode on your device.

→ Check Flight Mode by swiping down notification panel on your device with two fingers to access all of the Quick Settings.
