A buggy internet connection can cause communication issues. Delayed notifications and lagging chat messages are both extremely irritating. If your internet is very slow or prone to interruptions, you also can’t download files. This can cause problems both in your personal and professional life.

Don’t settle for an unreliable and sluggish internet connection. Explore your options and consider a few easy fixes. In many cases, you can repair this problem at home and get your high-quality net back within minutes.
Follow These Steps to Repair Your Internet Connection
If you are having problems with the Wi-Fi on your Galaxy S9 or S9+, here is what you need to do.
1. Turn Off Bluetooth
This is a known issue associated with the S9+. If the phone’s Bluetooth connection is switched on, the Wi-Fi slows down considerably. Here’s how you can fix that:
Start with the Home Screen
Swipe Up or Down to Open the Apps Screen
Open Settings
Tap on Connections
Select Bluetooth
Turn the Switch to OFF
Unfortunately, this method means you can’t use Bluetooth headsets or other accessories while you’re using the internet.
2. Erase App Caches
The Wi-Fi problem might be due to an app slowing down your system. First, you should clear your app cache data. This can give your Galaxy S9/S9+ a performance boost.
To get rid of cached information, do the following:
Open Settings
Tap on Device Maintenance
Tap on Storage – This option is in the lower-right part of the screen
Select CLEAN NOW
The next time you use any of your apps, it’ll download information instead of retrieving it from the cache.
If this didn’t help, try deleting a recently installed app. There’s a chance that it might have a glitch that slows down your Wi-Fi. You should also do a quick scan for malware.
3. Update Your System
Make sure your Galaxy S9/S9+ has the most recent system update. While this usually happens automatically, you can kick-start the process manually.
Follow this path to find any new updates:
Go into Settings
Tap on System updates
Select “Check for system updates” – Now, you’ll see a list of potential updates for your phone. Tap on the most recent one and select Download Now.
Select “Install Update” to Confirm
The installation will take some time to complete. If your Wi-Fi is extremely slow, you might need to use your cellular data to complete the process. When the installation is done, select OK.
Consider Resetting the Router
What if your phone doesn’t have any difficulties when it’s connected to other Wi-Fi networks? Sometimes the problem comes from the router rather than your phone.
If you suspect this is the case, you’d want to restart your router. Instead of using the restart button, unplugging the router and the modem is the most efficient option. Carefully disconnect them from each other and from the power outlet. Wait a few minutes before you plug them back in.
A Final Thought
If your Wi-Fi is still causing you difficulties, contact your carrier. They can advise you about changing some of your Wi-Fi settings. If you’re unlucky, it could be a system problem that’s out of your hands. You might have to wait and hope that Samsung’s next software update takes care of your problem.
