For the problem in the picture, the password input is correct. You can also connect to this WiFi normally before. At the same time, other devices can also connect to this WiFi network normally.
Check the advanced settings of WLAN on the mobile phone and no exception is found. If you ignore the network and re-enter the password, you still cannot connect. The prompt is: saved, protected by WPA / WPA2.
There are also many cases where the password is entered correctly, but it always shows that authentication is in progress.
In view of the above two problems, and more abnormal WiFi connection phenomena, hammer Gothic provides a variety of setting methods here to help the protoss solve the problems in WiFi connection.
Method 1:
Settings - General - WLAN - turn off the WLAN function, turn it off, then turn it back on and reconnect WiFi.
Connect to WiFi with mobile phone. After the initial connection, the mobile phone will retain a network IP address assigned by WiFi connection. It will be applied to the current WiFi. If there is no address conflict, you should be able to access the Internet normally, but if there is an IP conflict, you can try to solve it with the above method.
Method 2:
Settings - General - WLAN - select WiFi with abnormal connection - click the WiFi signal icon on the right - click Cancel to save - then re-enter the password and reconnect, so that the phone can get a new address and connect normally.
Method 3:
If the WiFi connection fails to connect normally when it is still in the authentication stage, you need to check whether the WiFi password is entered correctly, whether the WiFi password has been changed, or whether the security rules of the router are set correctly.
After the WiFi password is changed, the phone cannot connect. You need to update the WiFi password manually. WiFi password input error, also need to manually re-enter WiFi password. You can refer to the second method: settings - General - WLAN - select WiFi with abnormal connection - click the WiFi signal icon on the right - click Cancel to save - then re-enter the password and reconnect, so that you can get a new address and connect normally by operating the mobile phone.
Reenter the correct password and reconnect to the wireless network
Method 4:
If the above three moves fail to solve the problem, we can try to check the advanced settings of WLAN on the mobile phone.
Settings - General - WLAN - select WiFi with abnormal connection and long press - select Modify Network - display advanced selection, view and change proxy and IP settings according to router security rules.
In most cases, the proxy and port settings are not changed, but when WiFi has common problems, there is no mistake in choosing to view these items.
Method 5:
On the basis of the fourth method, if the default setting fails to connect normally, we need to consider or check whether there may be problems in DHCP address allocation on the connected router or whether the device has obtained the wrong IP address.
We can find the following settings: settings - General - WLAN - select WiFi with abnormal connection and long press - select Modify Network - display advanced options - IP settings change static, and then input relevant parameters according to the routing settings
We need to note that setting static IP address does not necessarily apply to all routers. If we can not get online normally when switching to other WiFi environments, we may need to restore the default settings or make appropriate modifications according to the router settings in the current WiFi environment.
Other methods:
When we encounter a WiFi that can't connect normally, and other WiFi can connect normally, we can try to solve the problem with the above methods, besides, we can also see if there is a problem with the router or broadband.
1. Check whether the connection between network cable and router is normal;
2. Check whether the broadband is normal. We can't be sure. We can contact the network provider, such as the 10000 of Telecom
3. Restart the router; hot start to release the router's battery;
4. Log in to the router web configuration page to view and modify relevant settings (common router configuration login address: 192.168.1.1 / 192.168.0.1)
5. If it's a home LAN, is Mommy in the next room watching Europa TV series using video playing software
6. My personal experience is to check whether the telephone line and network line at home are disorderly mixed together, and there is a phenomenon of horizontal fold, which also leads to frequent disconnection (it is the wireless router disconnection). As long as our WF is turned on and the wireless network is turned on, even if there is no broadband link, the icon of the link will be displayed on the mobile phone, which brings us the illusion that it is linked. The solution is to straighten out the disordered lines and solve the problem easily.
