The Samsung Galaxy S22 is built with advanced Wi-Fi 6 and Wi-Fi 6E capabilities for faster speeds and better stability. However, many users have reported issues with their device frequently dropping Wi-Fi connections, especially during streaming, downloading large files, or switching between apps. A reliable internet connection is essential for a modern smartphone experience, and this problem can be both frustrating and disruptive.
If your Galaxy S22 keeps disconnecting from Wi-Fi networks, the issue may be due to router compatibility, software settings, Wi-Fi interference, or firmware bugs. This article outlines the most common causes and provides a comprehensive guide to troubleshoot and resolve the problem.

📶 Common Wi-Fi Disconnection Issues on Galaxy S22
- Phone drops Wi-Fi and switches to mobile data automatically
- Wi-Fi disconnects during standby or sleep mode
- Frequent reconnection messages or failed attempts
- Connected but no internet access intermittently
- Only the Galaxy S22 has this issue while other devices remain stable
🔍 Common Causes of Wi-Fi Dropouts
Smart Network Switch or Adaptive Connectivity
Samsung’s Switch to mobile data or Adaptive Connectivity feature allows your phone to automatically switch to mobile data when Wi-Fi signals are weak. While useful, it can cause frequent and unnecessary disconnections from Wi-Fi, especially on crowded or unstable networks.
Wi-Fi Power Saving or Battery Optimization
Samsung includes aggressive battery-saving features that can put Wi-Fi or background processes to sleep when the phone is idle. This may lead to dropped Wi-Fi connections during standby or screen-off modes.
Router Compatibility or Band Switching
Dual-band or tri-band routers (2.4GHz and 5GHz or 6GHz) may cause confusion if the phone switches bands automatically. Some routers also have incompatible firmware settings that lead to Wi-Fi drops with newer devices.
Software Bugs or Outdated Firmware
After certain One UI or Android updates, Wi-Fi bugs may occur, especially if the system cache or network configurations are corrupted.
MAC Address Randomization
Samsung uses randomized MAC addresses for privacy, which can conflict with some router settings—especially those with MAC filtering or reserved IP addresses.
Interference from Other Devices
Nearby microwaves, Bluetooth devices, or too many connected devices can cause interference, especially on the 2.4GHz band.
✅ How to Fix Wi-Fi Dropping on Galaxy S22
Turn Off Smart Network Switch
- Go to Settings > Connections > Wi-Fi
- Tap the 3-dot menu > Intelligent Wi-Fi
- Disable Switch to mobile data when Wi-Fi is weak and Adaptive connectivity
This prevents the phone from abandoning Wi-Fi for mobile data unnecessarily.
Disable Wi-Fi Power Saving Mode
- Go to Settings > Connections > Wi-Fi > Tap your connected network > Gear icon
- Scroll down and tap Advanced
- Toggle off Wi-Fi power saving mode
This ensures Wi-Fi stays active even during low battery conditions or when the screen is off.
Set Wi-Fi to “Keep On During Sleep”
- Go to Settings > Connections > Wi-Fi > 3-dot menu > Advanced
- Tap Wi-Fi control policy
- Choose Always
Prevents the phone from disconnecting Wi-Fi in standby mode.
Forget and Reconnect to Wi-Fi
- Go to Settings > Connections > Wi-Fi
- Tap your network > Forget
- Reconnect by entering the password again
This clears out corrupted settings or saved IP conflicts.
Disable MAC Address Randomization (Optional)
- Go to Settings > Connections > Wi-Fi
- Tap the gear icon for your Wi-Fi network
- Tap View more > MAC address type > Phone MAC
Helpful if your router has MAC filtering or DHCP reservations.
Switch Between 2.4GHz and 5GHz Networks
- Test by connecting to both the 2.4GHz and 5GHz bands separately (if your router supports it)
- Use 2.4GHz for longer range; 5GHz for faster speeds in short range
Band steering or auto-switching can sometimes cause frequent drops.
Update Phone and Router Firmware
- Go to Settings > Software update > Download and install
- Also update your router firmware via its admin page (usually 192.168.0.1 or 192.168.1.1 in a browser)
Updates often resolve known Wi-Fi bugs and improve compatibility with new devices.
Reset Network Settings
If the issue persists:
- Go to Settings > General management > Reset > Reset network settings
- This will reset all Wi-Fi, mobile data, and Bluetooth settings
Useful after a system update or major network configuration change.
🛠 Additional Troubleshooting Tips
- Restart your router and phone to refresh network connections
- Reduce interference by keeping the phone away from microwaves or crowded Wi-Fi zones
- Try another Wi-Fi network (e.g., a public hotspot or mobile tether) to determine if the issue is device-specific or router-specific
- Use the Samsung Members app > Diagnostics > Wi-Fi to run hardware checks
📞 When to Contact Support
You should reach out to Samsung Support or your Internet Service Provider if:
- Wi-Fi drops frequently on all networks, not just one
- Other devices remain connected while the S22 drops repeatedly
- Diagnostics show Wi-Fi hardware malfunction
- Factory reset does not resolve the issue
A service center can run in-depth diagnostics or replace faulty wireless antennas if needed.
✅ Conclusion
If your Galaxy S22 keeps dropping Wi-Fi connections, it’s often due to power-saving settings, adaptive network switching, router compatibility, or software bugs. With a few tweaks—like disabling smart switching, adjusting power settings, and updating software—you can usually resolve the issue quickly.
Persistent problems may require a network reset, MAC address adjustment, or router configuration. If all else fails, Samsung Support can help identify potential hardware faults.
