What should I do if my phone can't connect to wifi?

There could be a number of reasons why you can't connect to Wi-Fi. Here are some common possibilities and workarounds:

1.Incorrect Wi-Fi password: Make sure that the Wi-Fi password you entered is correct. Check the upper and lower case, special characters, etc., to make sure the password is entered correctly.

2.Distance and signal strength: If you are too far away from the router, the signal may become weaker and cause connection problems. Get as close as possible to the router and make sure it's within its coverage.

3.Router issues: There may be problems with the router, such as the need to reboot, misconfiguration, etc. Try restarting your router and wait for a while before trying to connect again.

4.Wi-Fi Name Hidden: If your Wi-Fi name is hidden, you'll need to manually enter the Network Name (SSID) and enter the password to connect.

5.Device setup issues: Check your device settings to make sure that Wi-Fi features are enabled and that there are no settings that disable or block connections.

6.Conflicting IP addresses: If multiple devices use the same IP address, it can cause network connectivity issues. In the Duan Ling device settings in Can Chong, set the IP address to automatic acquisition (DHCP).

7.Router restrictions: Some routers may have limitations, such as MAC address filtering or access control lists. Make sure your device is on the list of allowed connections, or try turning off these restrictions.

8.Update issues: Sometimes the firmware or drivers of a device or router need to be updated to fix connectivity issues. Check for updates to your device and router, and update them whenever possible.

If the above methods still do not resolve the issue, we recommend that you contact your network service provider or device manufacturer for further technical support. They may be able to provide more specific solutions that work for your device and network environment.

1. Check whether the wifi password is correct.

It is recommended to click when entering a password"Eye icon"to display the password and make sure that the password is correct.

2. Reconnect to WiFi

Please go to Settings --WLAN, click on the wifi you need to connect to, and click"Forgot Network Forgot password"reconnect.

3. Check whether the wifi network is normal.

Please compare whether the same wifi connection is normal with other mobile phones, and confirm whether it is the wifi or mobile phone. If it is due to Wi-Fi, please restart the wireless router to check. At the same time, you can enter the router management interface to check whether there are special functions

For example, the number of connections is limited, MAC binding, Internet time splitting management, etc.

4. Reset network settings.

Do a good job of backing up wifi and other data, enter Settings - System Management - Backup and Reset - Reset Mountain Distribution Network Xiangyuan Weiluo Settings - Reset Settings, and then use to view.

Note: Resetting the network settings will clear the connection records such as Wi-Fi, mobile data network, Bluetooth, etc.; If you have dual SIM, you need to select the SIM card that corresponds to the training.

5. Reset all settings (do this when you can't see the reset network settings menu).

Note: Restoring all settings will not delete any software and files, only all settings of the phone's cover will be restored, and some third-party application accounts need to be logged in again.

If the above methods fail to help recover, the customer service center needs to be tested and processed (customer service center address: enter vivo official website vivo**app--my--service outlets, after-sales outlets--select provinces and cities to query the address of the customer service center).

If someone else can use this router, it's a problem with your phone.

Check out your router.

Hello, why can't I connect to my wifi? 1. Router failure This is the most common problem, it may just be a temporary connection into a dead loop, the easiest solution is to plug in the router power interface, let the router restart, which can solve 90% of the problems caused by the router. Of course, it is also possible that the router has a hardware failure, which can only be sent for repair.

Now the router** is not expensive before 50-200 yuan. In addition, there may be router configuration problems, which depends on whether the router itself can connect to the network, if it cannot connect to the network, the router needs to be reconfigured. 2. Multiple devices are connected at the same time Generally, this kind of problem occurs in the working environment, or in public places such as cafes and shopping malls that provide free wifi.

If you don't have the permission to change the settings of your router, you can only try to avoid surfing the Internet during peak hours, or connect to the Internet in advance. If there is an IP conflict, it is necessary to assign IP to each connected device in the router to avoid affecting each other. In addition, there are some examples, such as the Tianyi router given by China Telecom, which was forcibly locked by the official routing function, so if you want to use the Tianyi router for wifi Internet access, you must first unlock it.

3. Beyond the signal coverage The wireless signal of the wireless router will be weakened by external influences, the most direct is the distance, and the signal of ordinary routers will become very poor if it exceeds ten meters. Therefore, it is recommended to stay as close to the signal source as possible when connecting to WiFi to enhance the WiFi signal. In addition, if you have a medium barrier between you and your wireless router, such as a wall, the signal will become poor.

4. Wireless network card failure The mobile phone receives wifi signals by relying on the wireless network card in the mobile phone. Some mobile phone wireless network cards have been eliminated or seriously aged, which will cause poor wifi signal reception, and even a ** call will lead to the wireless network disconnection, which can only be repaired by the maintenance center. 5. Baseband or ROM problem Baseband is responsible for the communication module, often a mobile phone has multiple basebands to choose from.

If you brush an inappropriate baseband when you are flashing the ROM, it may cause your wifi connection to be abnormal, and even the text message cannot be sent, and the ** cannot be sent. In addition, if the ROM itself is not perfect, then there will also be the problem of an abnormal WiFi connection. For example, as soon as Android was released, some friends brushed the beta version of CM10 (framework-based third-party ROM), and the result was unable to connect to WiFi, which had to be solved by re-flashing a more complete ROM.
