The Internet has become more and more of a common service. Wireless networks are now available in most of the public places. And having a smartphone such as Samsung Galaxy S8+ Plus sure makes it a pleasure to use the Internet wherever you are. Nevertheless, Wi-Fi problems are still common.

With this flagship, for instance, users report a couple of common issues and reasons of discontent. Some of them deal with weak Wi-Fi signals. Others hate it when the Wi-Fi speed is going down. There are even users who don’t really know how to get rid of old Wi-Fi settings and log in with new credentials. And, of course, many have noticed, at some point, that the Wi-Fi tends to automatically switch to data even when they don’t want it.

In today’s article, we’re going to tackle four of the most common problems relating to Wi-Fi on Samsung Galaxy S8 and Galaxy S8+ Plus.

 

Problem 1 – How to disable the Smart Network Switch and fix the Wi-Fi

Not everybody affords to stay on mobile internet all day long. And why should you, especially when free wireless internet may be available? If your smartphone has a habit of automatically switching from Wi-Fi to mobile, you just need to disable the smart network switch:

  1. Turn on the device;
  2. Access the notifications bar and from the general Menu activate the mobile data connection;
  3. With the mobile data turned on, tap on the Settings icon and enter the Wireless section;
  4. Look for the option labeled as Smart Network Switch, somewhere at the top of the page;
  5. Uncheck this option and leave the menus.

 

Once you did this, from now on you will rely on a less stable wireless connection. But you can be sure that your Samsung Galaxy S8 or Galaxy S8+ Plus will no longer decide on its own to dump that Wi-Fi connection and switch to mobile data.

 

Problem 2 – The Wi-Fi is moving too slow

Wi-Fi speed is a common concern for all Internet users, whether they navigate from a laptop, a PC or a smartphone. With Galaxy S8 and Galaxy S8+ Plus, however, when the Wi-Fi moves slowly, you could also notice the icons or pictures from Facebook, Instagram, Twitter, Snapchat or WhatsApp are gray. Otherwise said, whenever you’re trying to access content with photographs, those photographs either upload very slow, or they don’t show up at all.

Our top suggestion for this kind of problem is to perform a wipe cache partition. A simple process, that won’t affect any of the data stored on your device, and that only takes a few minutes to put into practice:

  1. Turn off the device;
  2. Get the phone into Recovery Mode;
  3. Hold these three buttons until the smartphone starts to vibrate shortly – the recovery mode should start right after that;
  4. Look for an entry labeled as Wipe Cache Partition – you can use the Volume buttons to navigate through options;
  5. Once you’ve found it, highlight the Wipe Cache Partition option and use the Power button to start it;
  6. Wait for a few minutes until it is all completed;
  7. Use the Reboot System Now option to leave the Recovery Mode and get back to the normal functioning mode.

 

When the Samsung Galaxy S8 or Galaxy S8+ Plus restarts, the Wi-Fi connection should work flawlessly.

 

Problem 3 – How to forget a Wi-Fi network previously saved

We often save networks that we get in touch with on a regular basis. Who wants to keep connecting manually, with username and password, to the same network over and over again? The only problem is when the network changes its connectivity details. Or when you’re dealing with a Wi-Fi problem that requires you to reset the settings just so you can connect to that network.

When this happens, you will want your device to “forget” the data it has previously saved. To do so, you need to access the Wi-Fi section from the general Settings. There you will have a list with all the networks your smartphone ever connected to. From that list, you will have to select the network that is now causing you problems and make it forgotten:

  1. Turn on the device;
  2. Use one finger to swipe down the general Menu;
  3. Select on Settings;
  4. Browse until you reach the Network Connections section;
  5. Tap on Wi-Fi;
  6. Make sure that the Wi-Fi connection is turned On – if not, switch the toggle from Off to On;
  7. Tap on the Wi-Fi network profile you want to forget;
  8. Long press it until you see a context menu popping up;
  9. Tap on Forget.

 

Now that you have forgotten this network, you can scan for Wi-Fi networks in the nearby and try to reconnect to it once the smartphone detects it.

 

Problem 4 – Smartphone randomly switches from Wi-Fi to Data

Despite how annoying this may be, your Samsung Galaxy S8 or Galaxy S8+ Plus has the best intentions. It only randomly switches from Wi-Fi to Data in an attempt of finding a stable connection so you will have a flawless experience while navigating online.

And it does so with the help of a feature called Smart Network Switch. When the Wi-Fi you’re connected to is dropping signal or moving too slow, this feature will interfere and switch to a mobile network such as LTE.

Lucky for you, the feature is easy to disable, you just need to follow the steps we indicated to you in the first part of this article.
