Take an external one and see if it will be messy.

It's the wireless network that is faulty, or the laptop's wireless card is faulty.

There are several reasons why the wireless network is down:

1.The wireless network (wireless router) is faulty, or the line is stuffy and the bridge is not in good contact.

2.The wireless router is severely interfered with.

3.The wireless router has been hacked by a master, the settings have been modified, or the ARP attack has been carried out.

There are also several reasons for the failure of the wireless card of the notebook:

1.The wireless card hardware circuit is broken.

2.The driver of the wireless card is removed or is in the virus.

3.Wireless card routing attack.

Originally, after the sudden interruption, I could still search for a useless wireless network, which means that the wireless card of the limb sensitive notebook is good. After reinstalling the system or restoring the system, the default network is not a wireless card, but a LAN network card, just open the network neighbor attribute and set it to a wireless network until you can get a useless wireless network name, which proves that the computer wireless card work calendar is normal.

Then, the focus is on checking the wireless router.

1.Turn on the wireless router switch, and the wireless network name should be searched by the computer. And the signal is the strongest. If you still can't find it, it means that the wireless router has not turned on the wireless routing function, or it has been modified, or the transmission circuit is faulty.

2.Open the Neighbor properties and reset it to a LAN NIC. That is, it is set to wired NIC mode.

Then, connect the computer network card interface with a network cable, and enter the router login address in the IE window. After logging in, if you need an administrator password to enter the settings, the general administrator password is: admin.

For accurate information, please follow the wireless router manual. After entering, you can view the various settings of the router, especially the wireless routing setting switch should be turned on, which means that the wireless network function is turned on. And reset the wifi password.

3.The computer returns to Wi-Fi mode. You should be able to see your wireless network name, click, enter the wifi password, and the connection will be successful.

If you still can't see the wireless network name, but the useless wireless network can see it, it proves that your own wireless network router is broken, and you can replace it with a new one. Repeat step 2. Until you can see your wireless network name, the computer is connected to the wireless router normally.

Next, there is the question of whether you can access the Internet. Being able to access the Internet means that the connection mode of the original wireless router has not changed, which is normal. If you can't access the Internet, you need to reset the wireless routing connection mode.

There are two common wireless routing connection modes:

Automatic addressing. Set it to auto-address first, save and exit. See if you can get online.

If you can't access the Internet, it means that it is a real-name IP address. You need to consult the network operator's maintainer for the IP address.

Mode. Open the settings and enter the password provided by the network operator. Save-exit. The network is back to normal.

If you are in the warranty, you should go to the original factory to designate the after-sales service, which should be repaired free of charge, and if you are not in the warranty, you can repair it at will.

Laptops can be repaired wherever computers can be repaired. Computer glitches are all the same.
