You're staring at your Samsung Galaxy A56, and that Wi-Fi icon just won't fill in. It's stuck on "Obtaining IP address" or simply says "Saved, Secured" but refuses to connect. This is a common headache on Android 15 with One UI 7, but the good news is you can almost always fix it yourself without a trip to the repair shop.
Toggle Wi-Fi and Restart Your Phone
Start with the simplest fix. Swipe down from the top of your screen to open the Quick Settings panel. Tap the Wi-Fi icon to turn it off, wait a solid five seconds, and then tap it again to turn it back on. This forces your phone to drop the connection and re-scan for networks, which clears up a lot of temporary glitches.
If that doesn't work, give your phone a full restart. On the Galaxy A56, you can do this by pressing and holding the Volume Down button and the Side (power) button together for about 10 seconds. You'll see the Samsung logo appear as it reboots. This clears out any system processes that might be interfering with the Wi-Fi radio.
Use Airplane Mode to Reset Radios
This trick works on almost every phone. Turning Airplane Mode on shuts down all wireless communications, including Wi-Fi, cellular, and Bluetooth. After you turn it on from the Quick Settings panel, wait for about 15 seconds, then turn it off again.
This forces all the radios to reinitialize and reconnect from scratch. I've seen this resolve connection issues that a simple Wi-Fi toggle couldn't fix, especially after moving between different networks.
Forget and Re-add Your Wi-Fi Network
Your phone might be holding onto outdated or corrupted information for your home network. To clear it out, go to Settings > Connections > Wi-Fi. Tap on the name of the network you're trying to join, then select Forget.
Now, tap on the same network name from the list again. You'll be prompted to re-enter the password. Make sure you type it carefully, as passwords are case-sensitive. This is the fix if you've recently changed your router's password and your phone is still trying the old one.
Check for Router and Interference Issues
Before you spend more time on your phone, check the source. Unplug your Wi-Fi router from the power outlet, wait a full 60 seconds, and plug it back in. This gives it a clean restart. If other devices in your home are also struggling to connect, the router is almost certainly the problem.
Also, consider physical interference. Bluetooth devices and even some wireless peripherals can cause signal conflict on the 2.4GHz band. Try turning Bluetooth off temporarily from your Quick Settings to see if your Wi-Fi connection stabilizes. Thick walls or metal phone cases can also weaken the signal.
Disable Smart Network Switch in One UI
Samsung's Smart Network Switch is designed to be helpful, but it often causes problems. Its job is to switch you to mobile data if your Wi-Fi signal is weak, but it can be too aggressive and prevent a connection altogether.
To turn it off, go to Settings > Connections > Wi-Fi. Tap the three-dot menu in the top right, select Intelligent Wi-Fi, and then toggle off Switch to mobile data. This tells your phone to stay on Wi-Fi and stop second-guessing the connection.
Turn Off Power Saving Mode
When your Galaxy A56 is in Power Saving Mode, it limits background network activity to conserve battery. This can severely throttle or even cut your Wi-Fi connection. It's one of the most common culprits for intermittent drops.
Check this by going to Settings > Battery and device care > Battery. If Power Saving is on, tap it and select Turn off now. You should see your connection improve immediately if this was the issue.
Update Your Phone's Software
Software bugs can cause all sorts of connectivity problems. Samsung and Google regularly release updates with stability patches. To check, go to Settings > Software update > Download and install.
Make sure your phone is connected to a cellular network or, if possible, try a different Wi-Fi network to download the update. An update in 2026 could very well include a fix specifically for Wi-Fi issues on the A56.
Verify Your Date and Time Settings
This seems unrelated, but it's critical for network security. If your phone's date and time are incorrect, it can fail to validate the security certificates used by your Wi-Fi network, blocking the connection.
Go to Settings > General management > Date and time. Ensure that both Automatic date and time and Automatic time zone are switched on. This syncs your phone with network time servers.
Reset Your Network Settings
If you're still stuck, resetting network settings is a strong next step. This will erase all saved Wi-Fi networks, Bluetooth pairings, and mobile network preferences, returning them to factory defaults.
You can find this option at Settings > General management > Reset > Reset network settings. Tap to confirm. After the phone reboots, you'll need to re-enter your Wi-Fi password and re-pair Bluetooth devices, but it often clears deep-seated configuration errors.
Boot Into Safe Mode to Check for App Conflicts
A third-party app you installed could be causing the trouble. VPNs, ad blockers, firewall apps, or even certain "cleaner" utilities are frequent offenders. Booting into Safe Mode temporarily disables all downloaded apps.
To enter Safe Mode on the Galaxy A56, press and hold the Side button until the power menu appears. Then, tap and hold the Power off option on the screen. You'll see a prompt to reboot to Safe Mode. Tap it. If Wi-Fi works perfectly in Safe Mode, you know a downloaded app is the cause. Start by uninstalling recent apps or those that manage network connections.
Perform a Factory Reset
Consider this your absolute last resort. A factory reset will wipe your phone back to its original out-of-the-box state. You must back up everything important first, photos, messages, app data, because this process erases it all.
To proceed, go to Settings > General management > Reset > Factory data reset. Follow the prompts to reset the phone. Only use this step if every other fix on this list has failed, as it's a major undertaking.
