I think there are many people who connect to Wi-Fi at home to reduce the amount of packet communication on their smartphones, but I can't connect to Wi-Fi on my smartphone or computer, and I don't know why. ……How do you deal with such a situation? If your home Wi-Fi suddenly goes dead, here are the main causes and 8 solutions you should try.
Wi-Fi doesn't connect... Here are the main possible causes
Why did Wi-Fi not connect...? The main causes are said to be the following cases.
The causes range from simple to ones that you can't solve on your own. If you don't know which one is the cause of the Wi-Fi disconnection, please try the following 8 solutions in order.
8 Solutions to Try
If you can't connect to Wi-Fi and you don't know the cause, try the following methods to see if the problem can be resolved.
First and foremost, make sure the Wi-Fi device itself is turned on and the cable is securely connected. In the case of fiber-optic lines, check that all connections, such as the wall-mounted fiber-optic outlet, ONU power plug, LAN cable for connection, and outlet for the wireless LAN router, are secure. Also, in the case of a home router or pocket Wi-Fi that receives radio waves and creates a Wi-Fi environment, make sure that the power is on and the battery is not exhausted.
If your device is turned on and your cables are properly connected... but still can't connect to Wi-Fi, try restarting your device. Sometimes an error occurs inside the device and it is not working properly, but restarting the device may resolve this error.
Procedure when restarting the device
Wi-Fi may not be connected due to a problem with the settings on the smartphone or computer. Delete the Wi-Fi setting information set on your smartphone or computer, and try to re-enter the SSID and password.
For wireless LAN routers and home routers, it is printed on the bottom of the device. If your pocket Wi-Fi has an LCD screen, you can check it on the settings screen. In addition, it may be stated in the contract documents.
Wi-Fi radio waves differ in ease of connection depending on the frequency band used. Radio waves in the lower (lower number) frequency band are generally less affected by obstacles such as walls, and can reach distant locations. However, it is also characterized by being susceptible to radio wave interference from home appliances. On the other hand, radio waves in high (higher number) frequency bands are less susceptible to radio wave interference from home appliances, but are said to be more likely to be blocked by walls and other obstacles, making it difficult for radio waves to reach far.
Usually, the default setting is set to a low frequency band that is easy to connect over a wide range, but it is easy to interfere with home appliances such as microwave ovens, so it may be difficult to connect to Wi-Fi. If you feel that Wi-Fi is difficult to connect, you may be able to solve it by switching to a frequency band that is less susceptible to radio interference.
The range in which Wi-Fi signals can reach from a wireless LAN router or home router varies depending on how many obstacles, such as walls, are between the device and the location of use. If Wi-Fi is difficult to connect to, move to a room with better signal coverage, or change the location of devices that can be easily moved, such as home routers and pocket Wi-Fi, away from home appliances. It is recommended to see it.
If you are using a wireless LAN router connected to an optical line, you can use it in every corner of the room by installing a repeater near the room where the signal is weak.
Even after trying various things, I can't connect to Wi-Fi... Maybe there is a communication failure in the Internet service in the first place. In this case, unfortunately, you have no choice but to wait for the service provider to fix the problem.
You may not often see the official website of an Internet service provider, but information on the occurrence of communication failures and service suspensions due to maintenance is published on the official website.
Even if the official website does not disclose information about the problem, if you search on Twitter or other SNS and find many people in the same situation, it may be a communication problem...? maybe.
Even after checking the power supply and connection cable, there is no problem, and even after restarting the device and resetting the Wi-Fi, there is no connection or communication failure. In the unlikely event that it is possible, let's check whether there is an unpaid Internet service usage fee.
If you have any unpaid bills, contact your Internet service provider as soon as possible to find out how to pay the unpaid amount. Please note that if you leave it unpaid, not only will it be forced to cancel, but it will also affect your credit information.
If you can't connect to Wi-Fi even though there are no problems... If you're stuck, try contacting your Internet service provider.
Some service providers can only contact you via email or inquiry form, so whether or not you can receive solid support when such a problem occurs is also a factor in choosing an Internet service contractor. That's an important point.
