When the mobile phone connects to the home WIFI, it shows that the connection has been successful, and the IP address has been obtained, but it is not online. This is a lot of people who have had similar experiences. So why is it that the wireless network phone at home clearly shows that it is connected, but it cannot be used? There are many reasons for this problem, and the following will give you an analysis of the reasons and solutions for wifi display connection but not Internet access:
< br >
First, the router is unstable
< br >
Some wireless routers, light cat (broadband cat) quality is relatively poor, long-term operation after a series of problems such as crash.
< br >
Solution: Power off your home wireless router, light cat (broadband cat), wait a few minutes, and then switch on the power and start the device. After the normal startup, connect the wifi to test whether it can be used normally.
< br >
Two, broadband failure
< br >
If your home wifi, before the connection can be connected to the Internet, suddenly there is no Internet access to this problem. And the router and the cat have been powered off and restarted, but they still cannot be used after connecting to wifi.
< br >
In this case, it is very likely that there is a problem with the broadband line, or it is caused by the broadband arrears.
< br >
Solution: 1, first of all, call the broadband customer service phone, check whether your home broadband arrears? If it is overdue, make up the fee can be paid. 2, if there is no arrears, you can transfer to the manual customer service, fault declaration, let the operator arrange staff on-site service. PS: If you don't know how to dial up the Internet on your computer with a broadband connection, you can read the following tutorial to see how to do it.
< br >
At this time, the computer can be connected to the Internet, indicating that the broadband line is normal, there is no problem. On the contrary, in the case of no router, the computer is directly connected to the cat, the computer can not access the Internet, most of the broadband line has a problem.
< br >
3. The router is not connected to the Internet
< br >
If there are no problems with your broadband line, there are no overdue broadband charges, and your broadband carrier is not responsible for debugging your router. Then, at this time, please follow the steps below to check the relevant configuration in your router.
< br >
You can use a computer or mobile phone, first log in to the router's Settings page, find, open the Internet Settings or WAN port Settings options, you can see the router's networking status information.
< br >
If the message \"Networking failure\" is displayed on the router, read this part carefully. If the message \"Networking success\" is displayed, ignore this part and read the following content directly.
< br >
1. Check the line connection
< br >
An ordinary network cable router has one WAN interface and four LAN interfaces (some routers only have two or three LAN interfaces). Please follow the following method to connect the cables correctly.
< br >
(1) The WAN interface on the router needs to be connected to the network port of the cat with a network cable. If your broadband does not use the cat, you need to put the broadband network line into the home, plugged in the router's WAN interface.
< br >
(2) If you have a computer at home, you need to use a network cable to connect to the LAN interface, any LAN interface is OK.
< br >
important explanation
< br >
(1) At present, some routers have the WAN\/LAN interface adaptive function, this type of router, when the line connection, you can connect at will, do not worry about the wrong network cable.
< br >
(2) After the correct line connection of the router, the computer is not connected to the Internet at this time; But don't worry, this is normal. Because when you use a computer to set up a router, you don't need a computer to have Internet access.
< br >
2, check the Internet access.
< br >
The Internet access mode in the router (some routers are called: networking mode, connection type, WAN port connection type, etc.), if the setting is wrong, it will cause the router networking failure, that is, it cannot be used normally after connecting to wifi.
< br >
3. Carrier restrictions
< br >
In some areas, broadband operators will restrict users from using routers to access the Internet by binding the MAC address of the user's computer. In this case, the router cannot be connected to the network after normal Settings.
< br >
Four, is restricted to the Internet
< br >
Almost all network cable routers have some features that can be used to limit the wifi connection of mobile phones and computers. If your mobile phone, laptop is limited, then the wifi connection will not be used.
< br >
If you are familiar with the router, then you can log in to the router's Settings page, find wireless MAC address filtering, network cable device access control, Internet access control, parental control and other functions, and turn off.
the reason may be
< br >
1, the wireless network itself is a problem, the wireless network may not be connected properly, resulting in no Internet access;
< br >
< br >
2, router problems, the router may overheat or damage;
< br >
< br >
3, may be broadband arrears, resulting in no Internet access.
< br >
< br >
A wireless network is a network that uses wireless communication technology. It includes both global voice and data networks that allow users to establish long-distance wireless connections, and infrared technology and radio frequency technology that are optimized for short-range wireless connections, and the use of wired networks is very similar, the biggest difference is that the transmission medium is different, the use of radio technology to replace the network cable, and the wired network can be mutual backup.
One is that cell phone signals are spotty. This happens when you're away from a base station or in an elevator. The second is that the mobile phone is overdue, the operator has stopped the network, and this time you need to pay. Third, if you are using a wireless network, it is necessary to see if the signal wire of the wireless network is loose or there is electricity, and the right medicine.
< br >
If there is no network, please solve it according to the above method.
< br >
The reasons why you cannot access the Internet when you are connected to WiFi are:
< br >
1, the WiFi itself is a problem, the WiFi may not be connected properly, resulting in no Internet access.
< br >
2, router problems, the router may overheat or damage.
< br >
3, may be broadband arrears, resulting in no Internet access.
< br >
4, WiFi name contains Chinese, resulting in some computers can not connect to the Internet.
< br >
5, computer system problems, there may be a problem with the system, resulting in connection to the WiFi but can not access the Internet.
< br >
Suggested solutions:
< br >
1. Use other mobile phones or devices to connect to WiFi to try to get online and eliminate the problem of WiFi itself.
< br >
2, restart the router to try, or restore the router to the factory Settings, and then re-dial the Internet, and reset the WiFi according to the setting wizard, or replace the new router and dial up the Internet.
< br >
3, contact the broadband customer service, confirm whether the broadband account is abnormal, such as arrears, recharge the broadband, and then try dial-up connection.
< br >
4. If the name of WiFi contains Chinese, it is recommended to change it to English or a combination of English and numbers before connecting.
The phenomenon of being able to connect to WIFI but not being able to access the Internet may have several reasons:
< br >
1. The network parameters of the wireless router are incorrectly set, and the office device of the ISP operator cannot be dialed, and the Internet cannot be accessed.
< br >
2, the broadband line is faulty, the router can not dial the ISP operator's office equipment, can not be connected;
< br >
3, broadband DNS server for some reason can not provide domain name resolution services, its external phenomenon is very similar to the Internet, easy to be confused as network obstruction;
< br >
4, broadband due to the expiration of the ISP operator cut off, need to go to the business hall to pay for renewal;
< br >
5. The router sets IP address filtering, and the IP address obtained by the mobile phone is in the IP segment prohibited from accessing the Internet;
< br >
6. The router has enabled timed dialing, and the current time is not within the automatic dialing period;
< br >
7, the modem power is turned off, the router can not dial the network;
< br >
8. The network cable connecting the modem and the wireless router fails, such as being bitten by a mouse or being flattened by furniture or having poor contact with the crystal head, resulting in the router not being able to connect to the network.
The reason may be: wireless channel interference, the router itself, the light cat, and the outside line, need to be investigated one by one.
At present, the problem of interference in the wireless router in the family mainly appears in the interference of 2.4G WIFI.
