Hello everyone, Lin Fei to answer the above questions, why the mobile phone can not be on the Internet also shows 3G, why the mobile phone can not get on the Internet, many people do not know, now let's take a look!

The mobile phone signal is full, the password is correct, there is no bad sign, but can not get on the Internet. Why can't the phone connect to the wifi to connect to the Internet? In general, there may be something wrong with the mobile phone, router, network and so on.

Network anomalies such as mobile Ip conflicts and authentication, router mac filtering or speed limit settings, wifi password modification, broadband account errors or current network problems.

Intellectual property conflict

This wireless WiFi was able to connect normally before. Suddenly, only your phone connection doesn't respond, but everyone else's phone can connect properly.

Reason

[1] after the mobile phone is successfully connected to the wireless WiFi, the router will assign an IP address, and the mobile phone will be saved automatically.

[2] if you don't connect for a long time, IP will be assigned to others to use. When your phone connects to this wireless WiFi again, there will be an IP conflict and the connection will not respond.

Finish it.

[1] restart the mobile phone wireless WiFi function.

Turn off and restart the mobile phone wireless WiFi function and wait for the router to reassign the IP address to avoid conflicts.

[2] Delete and reconnect.

If you restart the phone's wireless WiFi function or the connection does not respond, you can click "forget" the wireless WiFi, and then when you reconnect, there will be a box to re-enter the wireless WiFi password, which will resolve the IP conflict.

IOS system 3360

Click Settings-WLAN-wifi- ignores the blue exclamation point on the right side of this network

Android:

Click Settings-WLAN- long press the wifi signal flag-unsave the network.

Identity authentication problem

The connection has been displayed in the authentication, but the connection is not available. At this point, you can check to see if the following problems exist:

1. Whether the wireless WiFi password is entered incorrectly

Whether the 2.2.wifi password has been modified

3. Whether the security rules of the router are set incorrectly.

Finish it.

[1] check the wireless WiFi password

1. If it is your own wireless WiFi, you can enter the router to see if the password has been changed.

two。 If it is someone else's wireless WiFi, you can ask to change the password.

3. If it is indeed modified, you can delete the original cached password and re-enter the correct password.

4. Check that the router has some security policies that restrict the connection of MAC or IP addresses, such as blacklists, or the corresponding speed limit policy. If so, turn it off, otherwise, only devices with specific MAC or IP addresses can be connected.

[2] IP address assignment

If it is the default setting or cannot connect, consider the router DHCP assignment problem or the phone got the wrong IP address.

Routers: check if the DHCP allocation function is turned off

Mobile phone: take I0S as an example, click the blue exclamation point to the right of the-WLAN-wifi-ip address to select [static], and then enter the relevant parameters according to the routing settings.
