Routers can connect on the Internet is not the reason why:
Router Setup problem;
The problem of the network itself;
Connect a hardware failure problem such as a device or router.
Cause the router can connect, but not on the above three kinds of situations, for users, if encountered this situation, the most important thing is to learn how to troubleshoot problems, to be good at using the elimination method.
First, simple analysis method
First, we need to analyze the situation for example, before the router can, they have not set up a router and connection and other related things, suddenly appear this fault, this situation can be ruled out is the problem of router settings, so can be used before, and did not turn anything, so the problem is mainly focused on the network itself or the problem of hardware failure.
How to judge the network itself or the hardware problem? If the router is connected through the cat, you can disconnect the cat and the router, direct use of the cat even the computer, try to dial the Internet, if you can then the network itself is not a problem, the problem appears in the hardware, if the dial-up can not access the Internet, The problem must be in the network itself, such as operator line problems or maintenance, you can try later or call Customer service telephone consultation.
If it is because the router has been set up or to the mobile phone/computer and other connected devices to make some settings caused by the inability to access the Internet, the problem is mainly on the device, focus on checking the settings changed.
Ii. Elimination of the law
If you encounter a router can not be connected to the Internet how to do, we can use a simple exclusion, such as watching other connections to the network users can surf the Internet, if you can not access the Internet, you can only be a router or network itself problems.
If other people can access the normal Internet, only their own devices can connect, but not the Internet, you need to check the connection network DNS settings and IP address settings, the general will be changed to automatically get the two.
About the router can be connected to the Internet is not the solution to introduce to everyone here, here need to remind everyone is that the ability to connect to the router does not mean that the network itself must be normal, do not believe everyone to try, the router to access the network cable unplug, users can still connect the router, but not the Internet, so encountered this problem, Do not blindly think that the device settings or the router set the problem, if you can use before, and did not set anything, so many times is the network itself caused by the question and answer, and so may be good.
If it is a new router, you need to set up before you can use, the details can be specific to see the relevant brand router Setup tutorial.
