What should I do if my laptop can't find wifi?

1. Why can't my laptop suddenly find a wifi solution?

Please refer to the following steps for setting:

1. First, confirm whether the wireless switch is turned on. For example, ASUS: press FN+F2 to turn on the wireless switch.

2. Confirm whether the wireless service is turned on. Method: Please click "Run" in the start menu, enter services.msc, and find WLAN auto config (or wireless zero configuration) to see if it is turned on. If not, please try to open it.

3. If it doesn't work, you can also open the Click Start menu-Control Panel-Network * * * Enjoy Center-Manage Wireless Networks, delete the previously saved wireless networks, then turn off and turn on the wireless switch, and connect the test again. You can also open the Network * * * Enjoy Center-after managing the wireless network, right-click the icon of the wireless network you want to use, select Properties, check "Connect automatically when this network is within range" in the connection tab, and then click OK to exit.

4. If you can turn on the wireless switch normally, you can search the wireless network, but you can't connect. If you are using a wireless router, please open the home page of wireless router settings to see what the value of "frequency band" or "channel" is. You can try changing it to "6 or 9". You can also try restarting the wireless router or resetting the router. In addition, if other computers are using this wireless network, it is recommended to disconnect other computers and try to connect to the wireless network only with this notebook. Alternatively, you can change other wireless networks to see if they are properly connected.

5. If the problem still exists, this situation may be caused by a problem with the driver of the wireless network card. I suggest you try to reinstall the wireless network card driver.

2. How to search the wireless network with a laptop? Thank you.

First, you need to install a wireless network card and insert it into the PCMCIA slot.

The Automatic Wireless Configuration Wizard will start. Follow the steps in the Automatic Wireless Configuration Wizard.

After completing this wizard, your computer can connect to the network. Windows XP will automatically find available wireless access points around.

If there is a wireless access point, Windows XP will try to connect to it. Sometimes, you may find that even if there is a wireless network around, Windows XP can't recognize it.

If this happens, you need to add the wireless access point manually. The method of manually installing the wireless access point is as follows: 1.

Click Start, and then click Control Panel. 2。

Double-click the network connection. 3。

Right-click the wireless network connection, and then click Properties. 4。

Click the Wireless Networks tab. The list of wireless access points will be displayed in the Available Networks box.

5。 Under Preferred Networks, click Add.

6。 In the Network Name (SSID) box, type the name of the access point and select the appropriate check box according to the network requirements.

You may need to consult your LAN administrator for specific settings. If you are in a domain, you may need to request a client certificate.

7。 Click OK.

After adding a new access point, you can connect to the new network. .

3. The laptop can't search for the specified wifi, that is, it can't connect to the home wifi. It doesn't require love knowledge.

Regarding the notebook computer, the wireless network card cannot search for the specified wif routing signal.

Let me help you analyze it. The main points are as follows: 1. It may be that the settings are messed up after manual connection. Go to your laptop official website and download the latest version of the same wireless network card driver.

2. Then enter the device manager, find the wireless network card device, right click-uninstall, delete this driver software-OK. Then you are installing the wireless network card driver downloaded from your laptop official website.

Restart the notebook to see if it is solved. 3. If it has not been solved, it may be caused by wireless instability of the router.

You can restart the router to see if it is solved. If necessary, you can enter the router management interface to restore the router factory settings; Or press the reset button on the back of the router to reset and see if it is solved.

Let's talk about the top first. If you have any new questions or questions, please ask them in time. I can really help you.

4. What if the laptop can't find its own wifi?

The laptop can't find its own method of wifi: 1, turn on the router, which is usually 192. 1 68.0.1or192.1.

2. Turn on the wireless settings. 3. The above reasons are generally channel problems. When you open it, you will see that the default check box is automatic.

You can put it under channel 7 and select 1 channel. Note: The above solutions are limited to: you can't detect your own WIFI, but you can detect other WIFI.

Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), usually using 2.4G UHF or 5G SHF ISM radio frequency band. Connecting to WLAN is usually password protected; But it can also be open, allowing any device within the WLAN range to connect.

Wi-Fi is a brand of wireless network communication technology, which is owned by the Wi-Fi Alliance. The purpose is to improve the interoperability between wireless network products based on IEEE 802. 1 1 standard.

Some people call the local area network using IEEE 802. 1 1 series protocols wireless fidelity. Even equate Wi-Fi with wireless Internet (Wi-Fi is an important part of WLAN).

5. What should I do if my laptop at home can't search for WIFI?

way

In the first step, after we tested a series of hardware settings and found no problems, I tried a method of manually adding network connections, as shown in the figure, and found the control page option in my computer startup item.

Step 2: Find the network and interests of the selected category in the control page as shown in the figure, and click to view the network status and tasks below. Then we entered the computer network connection management center. Although we are not connected to the network, we can check the status of the network internally.

The third step, in fact, this channel can be realized by another method, that is, click on the network connection status at the lower right of the laptop, and choose to open the network and the * * * enjoyment center. This method is more convenient than in the control page, and it is provided for users' reference.

The fourth step is the same. When we enter the network and the * * * enjoyment center, we can check the network connection status and control the operation of the network connection switch. As shown in the figure, we find a new connection or network by changing the settings under Network Settings.

Step 5, choose to manually connect to the following wireless network in the network setting dialog box, so that we can access the wireless network by adding the network connection address we received. Of course, the day before yesterday, i query knew the user name and password of our own home or the wireless network we want to connect to.

Step 6, as shown in the figure, I add my own home network, and choose to fill in the correct capacity in the network name, security type, encryption type and security key. The security type can be clicked on the small triangle, and wap2- Personal is generally selected. If it is an enterprise, choose the enterprise according to the individual situation.

Step 7: Click Next, and we will jump to the newly added network interface, so that we can successfully access the newly added interface. It should be noted that this method is to add wireless networks that we have not searched. If we add some networks that are no longer in the search range, it will not succeed.

Of course, I found another problem in the eighth step. The problem that some computers or mobile phones can't search for wireless signals may be because the wireless signals to be searched are Chinese characters, which makes the garbled codes unrecognizable. Then the solution is relatively simple, just change the wireless name.

The ninth step, such as using 360wifi, can modify the wireless network name by clicking the wireless icon to avoid garbled codes. Of course, not all devices don't support wireless network names that can't recognize Chinese characters, and operate according to the specific situation at that time.

Step 10: If you don't know how to modify it, you can click "Can't find this wifi" after the name of the wifi central network, so that the system will pop up a one-button repair button, which can automatically rename our network. By this method, most problems of searching for wireless signals can be solved.

6. Why can't the laptop find the wifi network?

The wireless connection of notebook computer can't find the solution of wifi: find the key with wireless switch function on your keyboard, which usually needs to be used with fn key, that is, hold down fn key and press it again.

If you don't have this key, look around your notebook to see if there is a switch for the wireless network card. If so, turn it on and see if you can search for a wireless signal. Laptop wireless connection can't find a solution for wifi: 1 .. Move the mouse to "My Computer", right-click and select "Properties".

2. Select "Device Manager" in the pop-up page. 3. Check whether the Network Adapter has been successfully installed and started in the device list.

If it is green, it has already started. If it is red, it means "Not started", and right-click and select "Start".

7. What should I do if my laptop can't find WIFI?

First, check whether WiFi is turned on.

1. Pay attention to the wireless network switch and shortcut keys of notebooks: In order to reduce power consumption and increase battery life, many new notebooks are designed with wireless network switches, which are turned off by default. In addition, some wireless switches are designed to be hidden, and it is difficult for users to find them. At this time, you need to turn on the wireless switch to connect to the wireless network normally. In addition to the wireless switch, many notebooks are also designed with shortcut keys (generally Fn+F5). Only press the shortcut key to start the wireless network card. 2. Turn on the mixed mode, and don't use 1 1n for exclusive use: after setting the wireless route, if the new notebook (1 1n wireless network card) can connect to the wireless network, the old notebook (1 1g wireless network card) can't. Solution: Enter the Web configuration interface of the wireless router and set the network mode to 1 1b/g/n mixed mode, so that no matter which standard wireless network card is used, you can easily connect to the wireless network. 3. Channel matching is very important, so automatic selection is recommended: the wireless network connection may be due to the channel setting. Generally, the channel setting range of wireless network cards is1-1,while the channel setting range of wireless routers is 1- 13. If the channel of the wireless router is set to 12 or 13, the natural wireless network card cannot connect to the network. Solution: enter the Web configuration interface of wireless router and set it in wireless settings->; Wireless channel, select1-1any frequency band to connect the wireless network card to the wireless network. It is suggested to select "Automatic Selection", so that the wireless network card will automatically select the channel, saving the trouble of user setting.
