In the Internet era, the network has entered thousands of households and all walks of life, and sometimes the laptop Wi-Fi connection is normal but can not access the Internet in the use of the network, and the reasons for the failure are caused by the following aspects:

1. The router is faulty.

The most suspicious is the power supply system, so the first thing that should be checked is the power supply system, to see if the power supply socket has current, whether the voltage is normal, if the power supply is normal, see if the power cord is damaged, whether it is loose, etc., if the power cord is damaged, replace one, if it is loose, plug it back in.

2. Wireless router.

Set up the issue. The wireless router can only connect up to 16 wireless devices, and if there are more, you will not be able to connect, some people can connect to the wifi, and some people can not connect, if someone disconnects the connected wifi, then the original person who cannot connect can be connected, and the number is equal. I checked it in the routing management panel and found that there were exactly 16 connected to wifi, and no more could be connected.

3. Out of the signal range.

This problem usually occurs because the refresh rate is set outside of the frequency range of the display. Beyond the signal coverage, the direct is the distance, and the signal of ordinary routers will become very poor if they exceed ten meters. So when connecting to WiFi, get as close to the source as possible to enhance the WiFi signal.

4. Set up the protected MAC address.

It is recommended to check whether the MAC address filtering function (blacklist and whitelist) is enabled on the router, and then restart the router after setting it again. The path of router MAC address filtering is generally as follows: router management interface - wireless settings - MAC address.

Filter, add your mobile phone MAC address to the allowed MAC address access list or remove it from the prohibited MAC address access list, there may be differences in the settings path of different routers, but the name of the setting item is roughly the same, if you can't find it, please refer to the router manual or consult the customer service of the device provider.

The reasons why the laptop is connected to wifi but can't access the internet are:

1. The wifi itself is a problem, and the wifi may not be connected normally, resulting in the inability to access the Internet.

Router. Problem, the router may be overheating or damaged.

3. Broadband arrears may lead to inability to access the Internet.

2. Restart the router to try, or restore the router for a while.

Factory settings. And then again.

Dial-up Internet access. And follow the setup wizard to reset the wifi, or change to a new router.

Dial-up connection. Internet.

3. Contact broadband customer service to confirm whether there is any abnormality in the broadband, such as arrears, recharge the broadband, and then dial up the connection.

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting.

5. If the above reasons are ruled out, it will be so long.

It is very likely that there is a problem with the computer system, and it is recommended to restore the factory settings. See if that solves the problem.
