Why can t the laptop search for a wireless network signal?

First of all, let's check if it's a wireless router problem. In order to confirm whether it is a problem with the wireless router, we can remove it and use the wired directly to surf the Internet (just like our desktop directly connects the cat to surf the Internet), if it can go to the Internet normally at this time, it proves that there is a problem with the wireless router, if it can't go to the Internet normally, it means that it is not a router problem.

The problem of the wireless router can be divided into hardware failure and setting problems, the probability of hardware failure is not high, it is generally caused by the setting problem of the wireless router, first of all, we need to confirm whether the wireless function is turned on. Go to the router settings interface, find the wireless settings, and then tap the basic settings to see if the wireless function and SSID broadcast are turned on.

In order to prevent rubbing the network, when turning on the wireless network, the Internet password is generally set, we should see if the correct wireless password is entered when using the wireless network, if the password is changed, do not forget to change the wireless password of the notebook that uses wireless Internet access.

There is also a "wireless MAC address filtering" option in the wireless settings, which can control the computer's access to this wireless network through MAC address filtering, the default filter rule is prohibited, that is to say, all MAC addresses added here can not access the wireless network, and allow is just the opposite, only the entries added here can access the wireless network, although the general user will not set it, just in case it is better to take a look.

Wireless routers are the most suspicious, but other possibilities cannot be ruled out, such as wireless network card drivers. The computer that does not install the wireless network card driver cannot receive the wireless signal, but the installation driver should also correspond to the model, if you don't know, you can install it under the detection of the software.

Although the possibility of hardware failure is very small, but it cannot be ruled out, for example, the failure of any hardware of the wireless router or modem may cause us to be unable to access the Internet, but we are not easy to judge whether they are faulty, so we leave this reason to the end, of course, if possible, you can try to replace them to confirm whether it is damaged.

When using wireless Internet access, you will often encounter the situation that you can't connect, the solution is to restart the modem and router, generally these two hardware will be in one socket, just turn off the main power and then turn it on. Every time the wireless network can't be connected, I use this trick, and I have tried and tested it repeatedly, and it is unknown why it can solve the problem.

Wireless configuration is still the main problem of wireless network disconnection, and it is necessary to check whether our wireless configuration is correct.

Sometimes simply restarting the modem or route will solve the problem, and it is best to restart both together.

The above is all the content of what to do if the laptop wireless network is not connected, I hope it will be helpful to friends in need.

The wallet sends a phone bill, 1 cent rushes 5 yuan for the phone bill.

Reboot to try, if it doesn't work, it's the password mechanism set by the router that your computer can't accept, and the general old-fashioned computer network card will have this problem, it is recommended to plug in the network cable.

Soda Satan Satan.

See a prompt to enter a key? That password is on the back of the router. Once entered, it will be connected to the router.

Then enter or, that's the address of the router, which has instructions in the router. Enter the router, in the WAN settings, fill in your broadband account information, generally in PPPoE mode, and you can use it normally after filling in and saving.

Is your router set up to surf the Internet? This is to connect the router to broadband first, then connect the laptop to the router, enter the router settings interface, set up the router to surf the Internet, and then the laptop to access the Internet through the router.

That's a problem with the router settings.

Some routers.

The laptop is connected to the mobile phone (the network is not recognized).

And so on are all router MAC address problems.

1. Make sure that the name of the wireless network you are trying to connect to is the same as the SSID set by the wireless router.

2. Please confirm the strength of the wireless signal, if the signal is weak, it is recommended to adjust the position of the wireless router or close connection.

3. Please confirm whether the wireless router is set to encryption, if encryption is set, check whether the encryption settings of the wireless network card and the wireless router are consistent.

4. Delete the original configuration file of the wireless network card on the computer and reconnect it.

5. Consult the manufacturer of the notebook or wireless network card, and operate the wireless network card for connection according to the relevant instructions.

6. If you still can't connect, please restore the router to factory settings and set it up again.

The password is wrong, it is recommended to check the password, paying special attention to the case.

The signal is weak, and the actual laptop can't transmit to the router, so it can't be connected. This kind of suggestion changes the location.

3.If the IP table of the router is full, it is recommended that the router be powered off for 20 minutes, and then power on and try again. Generally fine. If it still doesn't work, the router has to be reset and set up again.

Generally, the probability of 3 is relatively high, so it is recommended to start with 3.
