Hello, this is Pump Park TV. Today, we have received many inquiries about connecting to Wi-Fi. Usually, there are three things you can do when Wi-Fi is working well and then suddenly stops. The first is to turn off and on your mobile phone. The second is to turn off and on Wi-Fi. The third is to go into settings. Besides the Wi-Fi connection you have right now, on the right side, there is a gear icon. If you touch that icon, there will be an option to forget here. So, you can try deleting it and reconnecting. However, there are cases where it still doesn't work. In such cases, like with this S9 phone, let's try connecting to Wi-Fi once. You can swipe down, long press the Wi-Fi, go to settings, and touch connect. Then, if there is Wi-Fi in use, when you touch Wi-Fi, it will ask you to enter the password. Where is the password? Let's take a look for a moment.

When you look here, this is a typical Wi-Fi router you have at home. Here, it says wireless network. Yes, if you enter the password on your phone, you can connect. Let's try it once. Here, let's type the password once. After entering it correctly, let's try to connect. When the internet connection is not stable, it shows like this. Just touch the Wi-Fi connection here. When you see Wi-Fi AP here, it means the Wi-Fi is not connected. Usually, when you connect to Wi-Fi, it should work, but sometimes it doesn't. Everything here works well, so just connect to Wi-Fi. Even if you turn off the data now, the Wi-Fi connection is still good. Even with the data turned off, the Wi-Fi connection is working well. But why isn't this working?

If there is an exclamation mark after Wi-Fi appears 4, it won't connect. There are various reasons for this. You can try turning your phone off and on, turning Wi-Fi off and on, or deleting the existing Wi-Fi address and reconnecting. However, even after doing these, there are cases where it still doesn't work. Yes, in that case, one thing to check is, if you go to Settings, then scroll down to General. Under General, you can see, we learned how to change the date and time in the past. If you have traveled abroad or set the time you want, if you see that the date is set incorrectly like March 2, 2021, then the internet won't connect when the date setting is wrong and automatic setting is off. In that case, if you simply touch the date and time automatic setting, the Wi-Fi will connect right away. This is because it's a demo device, so only the internet is.

If you connect, it works right away. However, one thing to be careful of is that even if you use it well like this, there are times when it suddenly doesn't work. That is, if you happen to go to the time setting here, usually the default time is used, but there are times when you have to change the time unavoidably, like when going abroad or adjusting it to the time you want. At that time, turn this off, then as you learned in the past, even if it is January 1st now, if the date changes, for example, to March 1st, when the date changes regardless of the time, the internet connection is lost. If you look closely, it says here 5 connected to the internet. Right now, there are no exclamation points or anything like that here. The Wi-Fi is working well with the up and down arrows, but it's not working. For example, it won't connect. If this happens, it means it's not working. Other phones are working, and they are connected to the same Wi-Fi, and the signals are all strong, but it won't connect when you try to use it.

I can't log in like this. Choose a free 2 and still no internet connection. In this case, there are many variables, but basically, you should check a few things. First, check if your phone is connected. Second, turn off Wi-Fi once and then turn it back on, and also delete the default settings. Even after doing all this and it still doesn't work, then close the window, go to the settings button, and go to General. Go to Date and Time, and if the Date and Time automatic setting is off, turn it on. If the date setting is incorrect even when it's on, it won't work. Simply, if you set it to automatic here, it will connect right away. Look, it comes out right away. It comes out immediately. It works well. So, if Wi-Fi is clearly on and connected but still doesn't work, as I mentioned, go to General, go to Date and Time, and make sure to set it to automatic like this. If it still doesn't work, do this, then turn it off and on.

While using this, as I mentioned earlier, if you turn off the automatic setting, it won't work right away. The important thing is that when you turn off the automatic setting, it won't work right away. The crucial point is that the date and time set initially match well, so even if you turn it off and on, it works fine. However, the important thing here is that if you accidentally touch the date, it will change. The date and time are being set now. But the crucial point is that while using it like this, even if you secretly change the date and time at first, the internet Wi-Fi works well. But if you turn off and on your phone, after turning it off and on, if you turn on the Wi-Fi, the internet connection is not working. Of course, at first, it may catch a weak signal, so the Wi-Fi signal above is on normally. So, to summarize, if the Wi-Fi is not working well, try three different methods. If it still doesn't work, go to settings, and if the date and time automatic setting is off, just turn it on. Then everything will work fine.

The problem will be solved like this, it will be fine. Yes, that's right. When the Wi-Fi is not working, if you turn off and on the power of your phone or Wi-Fi router, erase the default settings, and enter the password again, it should work. If it still doesn't work after doing this and suddenly stops working, then if the date and time are turned off, just turn them on. For simple issues, just turn it on. By doing this, you can use your Wi-Fi again. If it still doesn't work after trying this and it works with other devices but not yours, then I will provide you with information. If it still doesn't work even after that, please contact the mobile phone manufacturer for advice. Yes, today we looked at one of the various situations when the Wi-Fi suddenly stops working after working fine during the setup. Thank you for watching today.
