How to Fix Wi-Fi Not Connecting on Android or iPhone

✅ Quick Answer

Wi-Fi connection issues are usually caused by weak signal, wrong password, router glitches, or outdated phone software. Restarting the router, forgetting the network, resetting network settings, or updating the device often resolves the issue.

❓ Why Phones Fail to Connect to Wi-Fi?

Phones may fail to connect to Wi-Fi due to incorrect password, interference from other networks, IP conflicts, or temporary software glitches. Sometimes, old firmware on routers or outdated phone OS can block the connection.

🔧 Fix 1: Restart Phone and Router

The simplest solution is to restart both devices to clear temporary glitches.

Turn off your phone.
Turn off your router and modem.
Wait for 30-60 seconds.
Turn on router and modem first, then phone.
Try reconnecting to Wi-Fi.

🔧 Fix 2: Forget and Reconnect to Wi-Fi Network

Removing the saved network clears password or IP conflicts.

Go to Settings → Wi-Fi.
Select the problem network.
Tap Forget Network (iPhone: "Forget This Network").
Reconnect by entering the correct password.

🔧 Fix 3: Reset Network Settings

Resetting network settings restores all Wi-Fi, Bluetooth, and cellular configurations.

Android: Settings → System → Reset → Reset Network Settings.
iPhone: Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.

🔧 Fix 4: Check Wi-Fi Password and Router Settings

Ensure you are entering the correct password and that the router is not blocking the device.

Confirm password matches exactly (check capitalization).
Check router's MAC filtering or parental control settings.
Restart router after any changes.

🔧 Fix 5: Update Phone Software

Outdated OS may cause connectivity issues.

Android: Settings → Software Update → Download & Install.
iPhone: Settings → General → Software Update → Download & Install.

❓ Frequently Asked Questions

Why does Wi-Fi say 'Saved, no internet'?

This occurs when the device connects to the router but the router has no internet access. Restarting the modem usually fixes this.

Why can't my phone connect to some Wi-Fi networks?

Some routers may block new devices, require updated security protocols, or have a weak signal in certain areas.

Does resetting network settings delete data?

No, it only removes saved Wi-Fi networks, Bluetooth pairings, and VPN settings. Personal files remain safe.
