iPhone Not Connecting to WiFi — Step-by-Step Fix

An iPhone that won't connect to WiFi or keeps dropping the connection is usually a network settings or router issue rather than a hardware fault. Work through these fixes in order.

Common causes:

Network settings on the iPhone have become corrupted
The router has an issue recognising the iPhone
iOS update reset network preferences
WiFi network password has changed
A firmware bug in the current iOS version

Forget the network and reconnect

Settings → WiFi → tap (i) next to your network → Forget This Network → Forget. Return to WiFi settings, tap the network and enter the password.

Toggle Airplane Mode on and off

Control Centre (swipe from top-right) → tap airplane icon → wait 10 seconds → tap again to disable. Resets all wireless radios.

Restart your iPhone and router

Hold Side button + volume button → slide to power off. Also restart the router (unplug for 30 seconds).

Renew DHCP lease

Settings → WiFi → tap (i) next to connected network → Configure IP → Renew Lease.

Reset Network Settings

Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. Clears all saved WiFi passwords and network configurations.

Check for iOS updates

Settings → General → Software Update. Apple releases iOS updates that fix WiFi bugs regularly.

When to call a technician

If the iPhone's WiFi chip is faulty (won't detect any networks at all), this requires physical repair. TechFix Pro provides iPhone repair across Western Sydney.

Frequently asked questions

Why does my iPhone keep disconnecting from WiFi?

Usually the router assigning a new IP address each time or iOS switching to mobile data when WiFi dips. Forgetting and rejoining the network resolves most persistent disconnection issues.

Why does my iPhone connect to WiFi but no internet?

The iPhone has a valid router connection but DNS is not resolving or the router can't reach the internet. Try renewing the DHCP lease and restarting the router.

Why is my iPhone WiFi slower than other devices?

Check which WiFi band it connects to — connecting to 5GHz gives faster speeds when close to the router.
