The laptop can't open the hotspot, this should be the laptop, he didn't have a function to open the hotspot, so he has no way to open the hotspot, but you can connect the hotspot of the mobile phone, this should be usable, because the computer is not carded, so he should also have no way to open the hotspot.

Some laptops have wifi switches, check whether there is one on the computer, and then turn on the wifi switch to search for hotspots. But if not, install a wifi module.

You may not have the wifi hardware function turned on, you can try to find out if the laptop has its own wifi switch, or whether there is a wifi open shortcut key in the f shortcut key. You can also try pressing the key win (start key) + x. Basically able to turn on wifi.

Because the laptop itself does not have a network, if it wants to access the Internet, it needs to connect to the hotspot or wireless wifi opened by other mobile phones.

If you don't have a network, you can't open it, first of all, check whether your network is good, and there is another one that you have to open the positioning.

First of all, please confirm whether your laptop has a wireless network card, whether the network card is enabled and whether the wireless network card driver is normal, generally these problems should be used.

The laptop does not have a hotspot, there is a wireless network, mainly after the hotspot of the router or mobile phone at home is turned on, you can connect to the computer.

Go to the network settings to see if it is disabled.

The mobile phone is set as a wifi hotspot and the notebook cannot be connected to the network, which may have the following situations:

1. Make sure that the laptop can access the Internet normally, that is, the "local connection" is connected to the network normally;

2. Determine whether the laptop has a wireless network card and whether the wireless network card is turned on;

3. Check whether the network share of "Local Connection" is set correctly;

Solution: 1. Check whether the "Local Connection" network is normal;

2. Reinstall the wireless network card driver and turn on the wireless network card switch;

3、a.Restart the computer, turn on the wifi, and select "Wi-Fi connection" in "Local connection" and "Home network connection";

b.Create a hotspot to connect (be sure to connect here, otherwise the following section will pop up a network sharing error dialog box);

c.Right-click on the "Local Connection" property and select "Wi-Fi" in the "Shared" tab to "Home Network Connection";

d.Disconnect the wireless hotspot and reconnect.

1. Open the "Service" management interface first, find "DHCP Client", "Network Location Awareness", "IP Helper", "WinHTTP Web Proxy Auto-DiscoveryService", and "Network List Service" to see if the current status is "Running".

If the "Startup Type" is "Manual", right-click and click "Start" in this service;

If the "Startup Type" is "Disabled", right-click on the service and select "Properties", set the "Startup Type" to "Startup" on the interface that appears, click "Application", then click "Start", and then click OK.

Once all the services involved have been completed, try to reconnect to the wireless network.

Press the windows key and the R key at the same time, enter cmd and click OK, then enter "ipconfig release" and press the enter key, and then enter "ipconfig new" and press the enter key, it will try to obtain the IP address again, and you can test whether it can be successful.

3. If the above operation is invalid, you can try to reset the network configuration and then restart the computer for testing.

Press the Windows key and the R key at the same time, type cmd, click OK, then type "netsh winsock reset" and press the enter key, wait for the display operation to be successful, and then restart the computer for testing.

4. The above operation is invalid, you can try to reinstall the driver of the wireless network card and then test.

According to the subject's description,It can be connected to other hotspots,It means that the network card driver of the notebook is no problem,The solution I give is as follows:

1. Click the network settings of the notebook WLAN management wifi settings Click the hotspot name of your phone and click Forget the network. Then reconnect your phone's hotspot and enter your password. See if you can connect to it. 

2. Due to the problem of the hotspot name, the notebook cannot be connected. It is recommended that if the previous mobile phone hotspot is with a Chinese name, then re-modify the hotspot name, all change to English letters or numbers, and then reconnect, because some computers are not good for Chinese wifi recognition.
