Children's boots that love to play with mobile phones can't do without WiFi. The mobile phone suddenly can't connect to WiFi. The WiFi password is right and the router is OK, but it just can't connect. Which link is wrong? Let Xiaobian solve it for you today.
First move: turn off and restart WiFi connection
If you use your mobile phone to access the Internet, you will keep a network IP address assigned by WiFi connection in your mobile phone. It will be applied to the current WiFi. If there is no address conflict, you don't have to worry. If there is a conflict, you have to close and restart the wi fi connection. The method is as follows: open the mobile phone menu, enter the 'Settings' column, enter the' WLAN 'project, and select' turn off WLAN 'in the new window. After the closing operation, re-enter the project, and select' turn on WLAN 'to restart the WiFi connection.
Second move: ignore the Internet
If the above does not work, you should choose to let Android devices ignore the network and add it again. The operation method is as follows: move out of the coverage of the network that needs to be ignored, select ignore the network, return to the coverage, wait for the network to display automatically, and then enter the network password to log in again. In this way, Android phones should be able to get new addresses and work properly.
Third move: check the WiFi password
Usually, after the WiFi password is changed, the mobile phone can't connect, so the WiFi password needs to be updated manually. Click the WLAN network address, choose not to save the network, and then re-enter the password.
Fourth move: View WiFi advanced settings
If none of the above methods can solve the problem, the next thing to do is to enter the advanced settings of mobile wifi for relevant settings. Open the phone menu, enter the 'Settings' window, enter the' WLAN ', then enter the' advanced 'option,' proxy server settings', and confirm that the device does not use the proxy server. If the IP address or domain name is found in the proxy part, delete it to solve the WiFi connection failure. Tip: in most cases, the proxy and port settings will not be changed; however, when there are common problems with WiFi, it is not wrong to select these items.
Fifth move: set static IP address
Another solution is to set a static IP address for the device. This indicates that there may be a DHCP address allocation problem on the router that the user needs to connect to, or the device has obtained the wrong address. In order to set the static IP address, you need to enter the static IP address setting column and enter the information (IP address, gateway, subnet mask, DNS, etc.). The only problem with setting a static IP address is that it will apply to all WiFi, so this method can only be used when the user is only connected to one WiFi.
Sixth move: turn off WiFi sleep strategy
If there are frequent problems with WiFi, you can try setting the wian sleep policy to off to see if the problem will disappear. If the policy is set to off, the power consumption will increase, but on the other hand, it will make the WiFi connection more stable.
