How to fix your Samsung Galaxy S9 Wi-Fi connection that keeps dropping (easy steps)

Network problems like Wi-Fi drops or intermittent Wi-Fi internet connection can be attributed to many different factors from the network base/towers issues to the wireless router/modem firmware glitches, and/or device software and hardware problems. That being said, you would have to consider looking into each of these factors when dealing with network-connectivity issues on your device. Here in this post, I’ve tackled a pertinent issue transpiring on the new Samsung Galaxy S9 in which the Wi-Fi connection keeps dropping. Read on to find out what options you can try on to troubleshoot and fix the problem on your end before rushing to a service center.

Before going further, if you found this post because you were trying to find a solution to your problem, then try to visit our Galaxy S9 troubleshooting page as we’ve already addressed most of the commonly reported issues with the phone. We’ve already provided solutions to some of the problems reported by our readers so try to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you and if you need further assistance, fill up our Android issues questionnaire and hit submit.

First solution: Reboot your wireless router/modem.

Minor firmware issues on the wireless router or modem can likewise cause wireless connectivity issues to occur on your smartphone. Note that the very core of your Internet connection at home is your modem or wireless router therefore, if something goes wrong with your network equipment, you can expect your devices to have troubles with Internet connection as well. To fix the problem, you can power cycle (reboot) your wireless router or modem. Here’s how you do it:

  1. Turn off your wireless router/modem by pressing on the Power button until it shuts down.
  2. Unplug the router/modem from the power source.
  3. After 30 seconds, plug it back in then turn on.
  4. Wait until all the light indicators get stable.

On your Samsung S9, reconnect to your Wi-Fi network then see how your Internet connection works this time. Usually everything should work properly after power-cycling the wireless router or modem. But if in your case it doesn’t, move on to the next applicable solution.


Second solution: Reboot your phone.

A simple reboot might be everything that’s needed to get your Wi-Fi Internet back to normal. This is especially true when it comes to network connectivity issues triggered by minor software glitches that randomly occur on any mobile device including your Samsung S9 handset. There are two types of reboot you can try on in this case — a soft reset and a forced restart.

Here’s how a soft reset or usual reboot is done on your Samsung S9:

  1. Press and hold the Power button.
  2. Tap the option to Power off.
  3. Tap Power off again to confirm.
  4. After about 30 seconds, press and hold the Power button again until your phone boots up.

Alternatively, you can do a soft reset with the hardware keys. Here’s how:

  1. Press and hold the Power and Volume Down buttons simultaneously for up to 45 seconds.
  2. Release both buttons when the Samsung logo appears.

Both of these restarts don’t affect any of your data and personal information stored on the internal memory so expect all your files to remain intact afterwards. Thus, there is no need to create backups.

Third solution: Turn Airplane mode on and off.

Airplane mode automatically turns off all wireless functions of your phone including Bluetooth, Cellular service, and Wi-Fi. So it somehow refreshes your phone’s wireless phone features and likely clears out minor glitches that might have inflicted Wi-Fi connection instability. Random network errors can be fixed by turning Airplane mode on and off shortly on your device. If you wish to give it a shot, then follow these steps to enable and disable Airplane mode on your Samsung S9:

  1. Navigate to Apps-> Settings menu on your phone.
  2. Tap Search then enter Airplane mode into the search field.
  3. Tap the slider to turn Airplane mode on.
  4. After 30 seconds, tap the switch to turn the feature off again.

Reconnect to  your Wi-Fi network then see if your connection is already stable. If it’s still dropping, then try the next step.

Fourth solution: Forget Wi-Fi networks on your Samsung S9.

It’s possible that your Wi-Fi network has been corrupted and is no longer working as intended. Should this be the case, forgetting your wireless network can potentially fix the problem. It works by deleting your wireless network in use from your phone’s networks drive/storage. Afterwards, you’ll add and set up the Wi-Fi network on your phone again. So it’s like the first time for your phone to connect to your wireless network. Here’s how it’s done:

  1. Open the Apps screen by swiping on an empty spot from the Home screen.
  2. Tap Settings.
  3. Select Connections.
  4. Tap Wi-Fi.
  5. Tap the Wi-Fi switch to turn on Wi-Fi, if necessary.
  6. Then tap and hold the wireless network that you want to delete or forget.
  7. Select the option to Forget network.
  8. If you see other saved Wi-Fi networks, delete them as well to prevent any of them from causing conflict.

After you have deleted all saved wireless networks from your phone, go back to Settings-> Connections-> Wi-Fi menu then set up your network and connect to the Internet to see if it’s already working stable. Proceed to the next solution, if necessary.

Fifth solution: Reset network settings on your Samsung S9.

A network settings reset might be needed especially if the problem is tied to incorrect network settings on your phone. These settings can be altered manually, if not automatically. Software updates particularly major firmware versions can automatically alter your phone settings, which might eventually have triggered certain issues including network-related errors to occur. As possible solution, you can try resetting network settings on your device with the following steps:

  1. Swipe up on an empty spot from the Home screen to open the Apps tray.
  2. Tap Settings.
  3. Tap General Management.
  4. Tap Reset.
  5. Select the option to Reset network settings.
  6. If prompted, enter the PIN or password for your device.
  7. Tap Reset settings to confirm action.

Other options

  • Factory data reset. If none of the prior solutions is able to fix the problem and that you’re still getting an intermittent Wi-Fi connection on your Samsung S9, then you may resort to a factory data reset. This will wipe everything from your device including personal information, customized settings, critical data as well as bugs and malware that likely causing your Wi-Fi connection to drop frequently.
  • Escalate software problem. Contact your carrier or Internet service provider to escalate the problem should it occur following a recent software update installation. You can also ask further assistance in performing more advanced procedures to troubleshoot more intricate network issues using a dedicated software.
