Hello, everyone, Lin Fei to answer the above questions, what to do if you can't find the wireless network? many people don't know if you can't find the wireless network. Now let's take a look!

1. Today's notebook computers all have their own wireless network cards, which can get rid of the shackles of wired and convenient for users to use. But sometimes there will be problems, so the laptop wireless card search can not find the wireless network signal? Don't worry, the author summarized several common failures and solutions, very comprehensive, I hope it will be helpful to you.

2. First, the wireless network card switch is not turned on.

3. Today's notebooks are generally equipped with switches or keyboard shortcuts to turn on and off wireless network cards. When you are not using a wireless network, you can turn off the wireless card to save more power and increase battery life. When your laptop cannot search the Internet, be sure to check the wireless card carefully to see if it is turned on.

4. Second, the wireless network card software switch is not turned on

5. Some computers need to turn on the hard switch of the wireless network card and check whether the software switch of the wireless network card is turned on (Intel wireless network card generally has this function). If not, you need to turn on the feature, as shown below:

6. In "Network Properties Wireless Network connection Properties General configuration Advanced", turn on "Wireless".

7. Third, the wireless network card service is not started.

8. The wireless network card requires the following services to work properly:

9, (1), wireless zero configuration

10, (2), wired automatic configuration

11, (3), Extensible Authentication Protocol Service

12. (4) automatic configuration of wireless LAN

13, (5), CNG critical isolation

14. Note: Windows XP SP3 needs to enable (1), (2) and (3) services, and Windows 7 needs to enable (3), (4) and (5) services. The activation method is as follows:

15. Click "start"run", enter the "services.msc" command, click "Service (Local)", find the corresponding service, double-click the corresponding service, and set the startup type to "automatic". If the start button is available, click it, and then restart the system.

16. Fourth, the wireless management software of the computer conflicts with the wireless management software of Windows.

17. The conflict between the driver management software of some computers and the wireless management software of Windows will also cause the failure of network discovery. Solutions are as follows:

18. Open the "Network Properties Wireless Network connection Properties Wireless Network configuration", tick before "configure my wireless network settings with Windows", and click "OK".

19. Verb (abbreviation of verb) incorrect signal frequency or wireless collision in wireless network configuration

20. When your computer used to work normally, now the environment suddenly changes, usually because the previous wireless configuration remembered in the computer conflicts with the current one (SSID is the same frequency but different, or the network name is the same but the password is different). Solutions are as follows:

Right-click "Wireless Network connection", select "Properties Wireless Network configuration", delete the contents of the preferred network, and click "OK". If it cannot be solved, you need to do the following.

22. Right-click Wireless Network connection and select Properties Advanced to ensure that any available network is selected.

23. The intransitive verb "event log" service is not turned on, resulting in the inability to search for wireless signals.

24. Click "start running", enter "services.msc", select the service (local), double-click the "Eventlog" service, and set the startup type to "automatic". If the start button is available, click enable and restart the system.

25, 7. The Microsoft Virtual WiFi Miniport Adapter service that comes with Windows 7 starts, causing Windows 7 to transmit wirelessly and interfere with the reception of the wireless network card.

Microsoft Virtual WiFi miniport Adapter in Network Adapter is a hidden function of Windows 7, Virtual WiFi. The traditional temporary wireless network is a point-to-point network, similar to the "dual-computer interconnection" in wired networks. Although the Internet can also be shared, it is mainly used for temporary interconnection between two devices, and some devices (such as those using Android systems) do not support temporary wireless network connections.

There is also a serious problem. Because a wireless network card can only connect to one wireless network, if you connect to the Internet through a wireless network card, you can no longer use this wireless network card to build a temporary network and share the Internet. The virtual WiFi function in Windows 7 can create a virtual network card based on a real wireless network card, realize the AP function of the wireless router, and solve all the problems of the temporary network.

28. When the Microsoft Virtual WiFi Miniport Adapter service is started, the wireless network card will automatically transmit the network with the same name, thus interfering with the reception of the wireless network card, causing Windows 7 to be unable to search the network.

29. The above is the introduction of several common faults and solutions that the notebook wireless network card can not search the wireless network signal. I hope it will help you!

At the end of this article, I hope it will be helpful to you.
