I am often asked if it is possible to launch an access point, and give out Wi-Fi from a computer whose Wi-Fi adapter is not built-in (like in laptops), but external or internal. Which connects via USB, or PCI. I wrote about such adapters in this article. As a rule, they buy external USB Wi-Fi adapters for regular desktop computers. It is through one of these adapters that today we will configure the access point and start the distribution of the Internet.
I will show on the example of the TP-LINK TL-WN721N adapter. Windows 10 is installed on the computer. I want to say right away that there is no difference between setting up an access point on a desktop computer via a Wi-Fi adapter, or on a laptop. Therefore, you can also configure it according to the instructions: how to distribute Wi-Fi from a laptop to Windows 10. And if you have Windows 7, or Windows 8, then there will also be no differences. The commands to launch the access point will be the same. If anything, here’s another guide to launching an access point on Windows 7.
I will run the hot spot through the command line. And if you want to use special programs to launch an access point, then see the article: Programs for distributing Wi-Fi from a laptop in Windows 10, 8, 7. There I wrote about the most popular programs that you can run and manage an access point. But, I would advise for the first time to configure everything with commands through the command line. And if everything works, you can use the program.
A few words for those who are not quite in the subject. In Windows, it is possible to launch a virtual access point, and thereby turn a laptop, or a computer with a Wi-Fi adapter into a router. He will distribute the Internet, which is connected to the computer via a network cable, or via a USB 3G / 4G modem.
Preparing a Wi-Fi adapter to launch an access point
The most important thing is that the computer detects the adapter and installs a driver on it. I think this should not be a problem. Drivers are on the disk with the adapter itself. If they are not, then you can download the necessary driver on the adapter manufacturer’s website for your model. Even an old adapter like TL-WN721N worked without problems in Windows 10, and I was able to start the access point.
For the time being, we will not delve into all the nuances with the drivers of the virtual adapter, etc. We do not need this yet. It is enough that after connecting the adapter to the computer, it is detected and Wi-Fi works.
If you want, then the team netsh wlan show drivers You can check if your wireless adapter supports launching a virtual Wi-Fi network. Just run the command on the command line. Find the item in the results "Hosted Network Support". Opposite should be "Yes".
If there is no support, then update the Wi-Fi adapter driver. If the update did not help, then try the tips in this article.
We figured it out. It remains only to execute a few commands, and you can connect to the wireless network that the computer will broadcast. We continue to configure.
Wi-Fi adapter as an access point. Setup in Windows 10, 8, 7
We will execute commands at the command line. It must be run as administrator. You can find the command line in the start menu, right-click on it and select "Run as administrator". Or, in Windows 10, you can simply right-click on the start menu, and select "Command line (administrator)".
Next, with the first command, we set the name of our Wi-Fi network, and the password to connect to it. To do this, we need to run the command:
"help-wifi.com" Are the names of the network that the Wi-Fi adapter will distribute, and "11111111". this is the password. You can change this data. Password minimum 8 characters.
Copy this command to the command line, and execute it. Such result should appear here:
The next command we launch the access point. To do this, run the command:
A report should appear "Hosted Network Running":
This means that the Wi-Fi network is already broadcasting, and you can connect your devices to it using the password that was specified in the first command.
We launched the access point, you can already connect to the Wi-Fi network. But, the Internet will not work on devices yet. You need to open sharing in the properties of your Internet connection. What we will do now.
We open the general access to the Internet for a Wi-Fi access point
Go to "Network and Sharing Center", and go to "Change adapter settings".
Now the important point: open the properties of the adapter through which you have connected the Internet. It does not have to be an adapter "Ethernet", or "LAN connection". There may be a connection with the name of your provider. Right-click on it and select "Properties".
Go to the tab "Access"put a tick near the item "Allow other network users to use the Internet connection of this computer". And from the list we select "LAN connection" (you can have it with a different number) Click Ok.
Internet on devices should work. If it does not work, then stop the network with the command netsh wlan stop hostednetwork, and re-run it with the command netsh wlan start hostednetwork.
After rebooting the computer, you will need to start the network each time with the netsh wlan start hostednetwork command. Or, make the access point automatically start on Windows.
Solving popular problems and errors
- Mistake "Failed to start hosted network. The group or resource is not in the required state to perform the requested operation.". I will not re-write the reasons for its occurrence and solution, but just give a link to a separate article: http://help-wifi.com/nastrojka-virtualnoj-wi-fi-seti/ne-poluchaetsya-razdat-wi-fi-s- noutbuka-na-windows-7-windows-10-8 /. In it, I wrote about the solution to this problem.
- Devices do not connect to a running access point. If possible, try connecting another device. Make sure that you enter the password correctly. As a rule, an antivirus or a firewall is to blame for this problem. Disconnect them. You can also try disabling the built-in Windows firewall.
- The internet is working. It is not uncommon that devices connect to Wi-Fi, but there is no Internet access. First of all, make sure that the Internet is working on the computer. Then, check the sharing settings. Let me remind you that you need to open shared access in the properties of the connection through which you have connected the Internet.
- In any situation, restart the computer and restart the access point using the netsh wlan start hostednetwork command.
The setup process itself is not complicated. But, often incomprehensible problems appear. Equipment, adapters and Internet connections are different for everyone. Therefore, certain nuances may arise. If you were unable to start the access point, then describe your case in the comments. We will solve the problem together.
