Introduction

A stable WiFi connection is crucial for fast browsing, streaming, and app updates on your Samsung Galaxy phone. However, even the latest devices running One UI 6 & 7 can experience WiFi problems — including frequent disconnects, slow speeds, or inability to connect to networks.
This guide provides step-by-step solutions for every common WiFi issue, along with exact menu paths, so you can restore a reliable connection on your Galaxy phone.

Step-by-Step Guide

Step 1: Restart Your Phone and Router

The simplest fix often resolves connectivity issues:

  1. Turn off your Samsung Galaxy phone → Wait 10 seconds → Turn it on

  2. Restart your router → Wait 30–60 seconds for it to fully reboot

📍 Menu path (for phone restart):
Press and hold Side Key → Tap Restart → Confirm

💡 Tip: Restarting resets network settings temporarily and clears minor glitches.

Step 2: Toggle WiFi Off and On

Sometimes, reconnecting fixes minor network glitches:

  1. Swipe down from the top → Tap WiFi icon to turn off → Wait 5 seconds → Turn it on

  2. Connect to your preferred network again

Step 3: Forget and Reconnect to Network

If a specific network is problematic, refreshing the connection helps:

  1. Go to Settings → Connections → WiFi

  2. Tap the gear icon next to the network → Tap Forget

  3. Tap the network again → Enter the password → Connect

📍 Menu path:
Settings → Connections → WiFi → Select Network → Forget → Reconnect

Step 4: Check Airplane Mode

Airplane mode disables all wireless connections:

  1. Swipe down → Check Airplane mode toggle

  2. If enabled → Tap to disable

Step 5: Reset Network Settings

This resets all WiFi, mobile data, and Bluetooth settings without affecting personal data:

  1. Open Settings → General Management → Reset

  2. Tap Reset network settings → Confirm

  3. Reconnect to WiFi networks afterward

📍 Menu path:
Settings → General Management → Reset → Reset network settings → Confirm

Step 6: Ensure Software is Up to Date

WiFi issues can result from software bugs:

  1. Go to Settings → Software update → Download and install

  2. Install any pending updates

💡 Tip: Also update apps from Google Play Store and Galaxy Store to avoid app-specific connectivity issues.

Step 7: Toggle Advanced WiFi Settings

One UI 6 & 7 includes options that can affect WiFi performance:

  1. Open Settings → Connections → WiFi → Advanced

  2. Options to check or toggle:

    • WiFi Power Saving Mode → Off

    • Keep WiFi on during sleep → Always

    • Switch to mobile data automatically → Off (prevents sudden disconnections)

Step 8: Check Router and Network

If multiple devices experience slow or no connection, the issue might be with your router:

  • Ensure firmware is up to date

  • Check SSID and password

  • Move closer to the router or reduce interference from walls/devices

  • Change WiFi channel in router settings if multiple networks interfere

Step 9: Safe Mode Troubleshooting

If WiFi works in Safe Mode, a third-party app is likely causing the issue:

  1. Press and hold Power button → Tap Power off → Tap Safe mode

  2. Test WiFi connection

  3. If stable → Uninstall recently installed apps one by one to identify the culprit

📍 Menu path:
Press & hold Side Key → Power off → Tap Safe Mode → Restart in Safe Mode

Step 10: Advanced Options (Static IP / DNS)

For persistent connectivity issues:

  1. Go to Settings → Connections → WiFi → Gear icon → Advanced

  2. Select IP settings → Static

  3. Manually enter:

    • IP address → Example: 192.168.1.100

    • Gateway → Router IP

    • DNS1 / DNS2 → Use 8.8.8.8 and 8.8.4.4 (Google DNS)

💡 Tip: Only use this if default DHCP doesn’t work reliably.

Troubleshooting / Common Issues

  • Disable Switch to mobile data automatically

  • Reset network settings if needed

  • Double-check password

  • Forget and reconnect

  • Try another device to confirm network is working
