This article mainly introduces why the wireless network card in the computer can not connect to the network, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

The possible reasons for the wireless network card can not connect to the network are: 1, the wireless network card driver is not updated or does not match; 2, the wireless network service is not activated; 3, the signal difference of the wireless router; 4, the wifi password has been changed, resulting in the wrong password can not connect to the network; 5, the wireless network is cut off; 6, the wireless network card is malfunctioning, and so on.

The wireless network card is not connected to the network (wifi). There are generally the following reasons for this:

1. The wireless network card driver is not updated or does not match.

Solution: start → Control Panel → system → hardware → device Manager → Network Adapter → right-click the wireless network card → update driver software → to complete the update step by step

2. Wireless network service is not activated.

Solution: start → Control Panel → Management tools → Service → Wireless Zero Configuration → enable

3. Some notebooks have physical switches to turn on or off the wireless network or the shortcut key Fn+F2, which can be turned off and then restarted.

4. Signal difference of wireless router

Solution: the launch distance is limited, if there is a corner, the signal will also attenuate, this difference is often ignored by users, first shorten the distance, gradually open the distance.

5. Router settings, DHCP and other services are not enabled

First open the browser of the computer connected to the current wireless router, enter 192.168.1.1 in the address bar (some routers are 192.168.0.1, see the bottom label of the router), log in to the web configuration interface of the current router, the user name and password are admin by default.

Click on the DHCP server and turn on the DHCP function to ensure that the router can assign the IP address to the device when it is connected to the LAN port or connected to the wifi.

Check to see if the wireless router has filtered out the MAC address, and if so, you need to add a new MAC address to the router settings. Otherwise, only devices with specific MAC or IP addresses can be connected.

If the above method doesn't work, disconnect and re-enter the password to connect.

6. Incorrect password

When entering the wireless connection password, if the password is long, you may enter the wrong password, or the wifi password has been changed, just enter the correct password. If possible, enter the password directly using copy and paste. When copying and pasting, be careful not to select extraneous characters. Adding one or two extra spaces is the most common mistake.

7. The wireless router has been bound to the MAC address

In order to prevent others from surfing the Internet, many home users have set up wireless Mac address filtering, but when the computer or wireless network card is replaced, it will not be able to access the Internet, so you need to add a new MAC address to the router settings.

8. The wireless network found is cut off.

In the network protocol, commonly known as fake death, the general occurrence of this situation is the problem of the wireless router, which can be solved by restarting the wireless router.

9. The wireless network card used has failed.

Can be divided into driver, hardware problems, test whether the driver or hardware problems, you can first reinstall the wireless network card driver software to see if it is correct, if still can not connect to the network normally, then it can be determined as the wireless network card hardware problem.
