How To Fix A Broken WiFi Module On An IPhone

If your iPhone's WiFi stops working (grayed-out WiFi toggle, no networks found, or frequent disconnections), don't panic! Here are some simple ways to fix it.

 

1. Software Fixes (For System or Settings Issues)

① Restart Your iPhone

Hold the Power Button, slide to turn off, then turn it back on.

② Toggle Airplane Mode

Turn on Airplane Mode for 10 seconds, then turn it off.

③ Reset Network Settings

Go to Settings > General > Reset > Reset Network Settings (this won't delete your data).

④ Reset All Settings

If WiFi still doesn't work, try Settings > General > Reset > Reset All Settings (no data loss).

⑤ Full System Restore (DFU Mode)

Connect to a computer, use iTunes/Finder to restore iOS (backup first!).

 

2. Physical Fixes (For Hardware Problems)

① Remove SIM Card & Restart

Power off, take out the SIM card, then turn the phone back on.

② Freeze Your iPhone (Temporary Fix)

Put the iPhone in a sealed bag, then place it in the fridge (not freezer!) for 10-20 minutes.

③ Heat It with a Hair Dryer

Use a hair dryer (medium heat) on the back of the iPhone (near the camera) for 5-10 minutes.

④ Re-solder the WiFi Module (Advanced Fix)

If the WiFi chip is loose, a repair shop can re-solder it.

 

3. Last Resort (If Nothing Works)

① Replace the WiFi Module

A repair shop can install a new WiFi chip (costs around 30−30−50).

② Go to Apple Support

If under warranty, Apple may fix or replace your iPhone for free.

 

How to Prevent WiFi Problems

✔ Avoid overheating (don't leave your iPhone in hot cars).
✔ Use original chargers to avoid power surges.
✔ Keep iOS updated to fix WiFi bugs.

 

Final Tip

If WiFi still doesn't work after trying everything, take your iPhone to a professional repair shop.
