Win7 system crashes when using wireless network card

Driver problem, it is recommended to change a few drivers to try, the latest is not necessarily the most suitable.

1。Software conflicts, incompatibilities: redundant similar software installations! The computer is overclocked or there is too much software installed, and the system memory is insufficient!

360 Butler, Software Uninstall, Find Uninstall, Again: Powerful Cleaning!

Or: Start Menu, Programs, Find Excess Software Uninstalled!

2。The computer system is interfered with by stubborn viruses and Trojans or worms, or you have lost your system files!

360 system first aid kit, start first aid, after finishing, restart the computer!

After booting up, [File Recovery Area], click on: suspicious startup items and Trojans, delete files completely!

Again: [System Repair], select all, fix it now! [Network Repair] to start the repair. Restart your computer!

Antivirus, Full Scan, Quarantine, Trojan and Suspicious Viruses, Point: Completely Removed!

4。Do it when necessary: restore the system or reinstall the system with one click!

5。Hardware problems, hard disk or motherboard or fan problems, send it for repair!

See if your win7 is 64-bit or 32-bit. It's best to change to XP to make sure you don't crash.

Fault phenomenon: The connection speed of wireless Internet access on the laptop is very slow, and it often fails to connect normally, and in severe cases, it will also lead to crashes.

Analysis and processing: It may be that the wireless Internet signal has been interfered with, resulting in the failure to connect normally and the computer crashes.

To resolve the issue, try the following methods.

Method 1: Check whether the energy-saving mode of the wireless NIC is enabled. In energy-saving mode, the transmit power of the wireless network card will be greatly reduced, resulting in a weakening of the wireless signal and affecting the transmission rate.

Method 2: Check whether there are any obstructions between wireless devices. If there is an obstruction between the wireless network cards or between the wireless network card and the wireless AP, it will seriously affect the transmission of the wireless signal and bury it early.

Method 3: Determine if there is interference from other electromagnetic devices. Equipment such as cordless ovens and microwave ovens will interfere with wireless transmission, resulting in a decrease in the transmission rate.

Since most microwave ovens use the 7th and 11th channels of the 14 channels on the GHz band, the communication channel of the IEEE protocol wireless device is fixed at 14.

It is likely that after inserting the wireless network card, the computer automatically installs a mismatched driver, resulting in a system crash or system hardware conflict or incompatibility.

Try changing a wireless card. Or update the motherboard driver.

1.The driver is not compatible, 2The hardware NIC is faulty.

There is a problem with the driver or there is a problem with your wireless card.

1. Installing too many operating systems on the same hard drive will cause the system to crash. It is best to format and clean it with PQ before reinstalling. 2. CPU, graphics card and other accessories should not be overclocked too high, and pay attention to the temperature, otherwise, it will restart or freeze inexplicably when starting or running.

In general, don't overclock casually. 3. When replacing computer accessories, be sure to plug them in, because poor contact with accessories will cause the system to crash. 4. BIOS settings should be appropriate, sometimes due to sudden power failure and other reasons caused by BIOS chaos, it can be discharged or restored to factory settings.

Question: Is it okay to restore the factory and lose the files in the computer?

It is recommended that you go to a repair point to recover.

Laptop freezes when connected to Wi-Fi for the following reasons:

1. The driver of the network card is incorrect, because the use of compatible drivers will lead to software conflicts and crashes, go to the official website to install the driver now, uninstall the network card before installation, and restart the computer to load the driver after the driver is installed.

2. There is a problem with the hardware of the network card, when it is used for a period of time, it will not work normally because of heating, resulting in an error in the bus and crashing, in this case, it will be shielded in the BIOS, and then the external wireless network card can be used.

Your wireless network card conflicts with that program, check the system's built-in event viewer, check the red cross in the system information (pay attention to the time of occurrence), find the cause of the system crash, and find the cause to solve the problem, it is recommended to replace the wireless network card.

Method 1: When our mobile phone or computer is connected to wifi, we must ensure that the wifi we connect to is correct. At this time, we can check whether the wifi name of our mobile phone or computer connection is correct.

2. Method 2: Try it on a different computer or mobile phone: When our mobile phone is connected to the wifi network, in order to determine whether it is a wifi problem or a mobile phone problem, you can use other mobile phones or computers to connect at this time to see if you can access the Internet.

3. Method 3: If the computer is not connected to the network, then we can plug it into the router with a network cable or, connect the computer to try it again, and try it with a wired to see if it can access the Internet normally. If it can, it may be that there is a problem with the router wifi, and if not, it also means that it is also a problem with the router.

1. Frankly speaking, although you said that you have updated the driver, but I still think that the possibility of the driver problem is relatively large, and the driver is not the newer the better, it is recommended that you use the driver life to change a few more versions of the driver to try...

2、Secondly, it may be a routing problem.,Let's set up the wireless routing according to my screenshot first.。。。

Change the automatic connection to on-demand connection or manual connection, all 0 minutes... After saving, restart the route...
