How to connect the Internet from a laptop to a computer

Is it possible to use a “laptop” Wi-Fi module in a PC

The laptop is a portable device and, accordingly, is equipped with modules that allow you to save space inside the case. Naturally, the topology of the printed circuit board and the shape of the connectors for connection change, which for portable devices is called “MiniPCIe”, while the pin assignment remains the same as for PCIe.

The schematic design does not change either, wireless controllers for both portable equipment and desktop personal computers are almost identical.

Thus, the answer to the question “Is it possible to connect a WI-FI module from a laptop to a PC” is unambiguous: yes, you can.

Note! In order to carry out operations with electronic components, at least basic knowledge of electrical and circuitry is required, as well as practical skills in working with soldering and auxiliary equipment. It should be remembered that working with radio modules on an intuitive level can lead to their failure.

Wi-Fi Card Connections (PCMCIA)

Everything is simple and easy here. Insert the card into the PC Card slot and install the driver if necessary. Some models will work without installing a driver.

If you are not satisfied with the speed or quality of the wireless Internet, keep in mind that you can always connect with a cable. How to do this correctly, see our previous article: connecting a laptop to the Internet via a cable.

Choosing the version of the WI-FI communication standard

Here is a list of the most popular and common Wi-Fi standards.

  • The first Wi-Fi standards that appeared: 802.11a, 802.11b, 802.11g. Their real average transfer rate is about 20 mb / s.
  • Then the 802.11n standard appeared, it allowed, under ideal conditions, to pump up to 150 Mbps with one antenna. If there were 4 antennas, then the speed reached up to 600 Mbit / s.
  • And to date, two more standards have been added: 802.11ac, in test conditions the speed was up to 6.77 Gbps with an 8x MU-MIMO antenna. And 802.11ax, introduced in 2019, with speeds up to 11 Gbps.

How to choose a Wi-Fi adapter

Today the range of wireless adapters is huge. Therefore, we will now show what you need to pay attention to when choosing a WI-FI adapter for a laptop or PC.

We connect an external module

It shouldn’t be difficult to connect with an external module. The procedure is so simple that any schoolchild can quickly cope with it.

  • We insert the purchased module into a free USB port on the computer.
  • We take the disk that should be included with the adapter and install the driver from it. If there is no such disk, then download the driver from the Internet.
  • After installing the driver, a wireless icon should appear in the corner near the clock. Click on it and connect to your network. If you do not know how to do this, then see our article: how to connect to a Wi-Fi network for the first time.

We connect the WI-FI adapter to your computer

Now we will show you how to connect different Wi-Fi adapters to your computer.

Homemade Wi-Fi adapter in a case from under a flash drive. Pinout of the laptop Wi-Fi module

Connecting a WI-FI module from a laptop to a USB (read as “USB”, Universal serial bus) port is quite problematic. To make a simple WI-FI adapter in a flash drive case, you will need:

  • a wireless module from an old tablet with an external 2.4 GHz antenna;
  • case from a USB flash drive with a female connector;
  • LED (optional);
  • soldering iron, solder, rosin or flux.

Next, you need to solder the contacts of the Wi-Fi module to the serial port connector according to the pinout. After that, also solder the antenna to the ANT and GND outputs, it is highly recommended to install an AL 307 type LED on the 3.3 V pin with the cathode and on the USB 5 V pin with the anode ( otherwise, it is necessary to solder by surface mounting the DCDC converter). Finally, collect everything and place it in the case from under the flash drive, if necessary, fix the parts with hot glue.

To connect using such an adapter, you need to connect it to the USB port and install the necessary drivers. Since the device may not be recognized by the system, it is recommended to download the drivers for it in advance on a miniature flash drive that can be placed next to it on the key fob. You can also make a two-way device out of such Flash memory, a WI-FI module and a suitable case: on one side there will be a drive connector with drivers, and on the other, a WI-FI adapter.

Attention! Soldering of electronic components should be done in a well-ventilated area. When working with the contact pads of modern printed circuit boards, the most suitable option would be to use a soldering iron tip for SMD components. If the radio component needs to be unsoldered, it is best to use the desolder, which is part of many amateur soldering stations.

Additional Information. When deciding how to connect a WI-FI module from a laptop to a computer, you should have a pinout at hand. a diagram indicating the purpose of the contact pads, for miniPCIe it looks like this:

How to set up L2TP connection in Windows 10

The L2TP tunneling protocol used to connect to the WAN is a symbiosis of the old PPTP protocols from Microsoft and L2F from Cisco. It is easily handled by network devices and has a high speed of information exchange due to the reduced load on the processor. It has great connection stability and high security. Able to create tunnels to work on any network. The L2TP protocol is usually used in corporate networks, since it allows you to create a network connection over an existing network. This provides a stable connection between the head office of the organization and regional offices.

To configure an L2TP connection, you need to perform a number of sequential steps:

  • Right-click on the Start icon.
  • In the menu that appears, click on the line “Network Connections”.

From the start menu select the line “Network Connections”

In the “Settings” section, open the “Network and Sharing Center”

In the menu of the “Network and Sharing Center” section, select the first item. “Create a new connection or network”

Highlight the line “Connect to a workplace”, then click “Next”

Click on the “Use my internet connection (VPN)” tab to proceed with the configuration

Enter the server address and do not forget to tick the last item to allow other users to use the connection

In the console, right-click on the generated VPN connection and go to “Properties”

VPN type must be set as L2TP with IPsec (L2TP / IPsec), for data encryption select “optional”

Authentication key must be provided to you by your ISP

If you did everything correctly, then the L2TP connection is ready to use.

The created L2TP connection increases the level of security for the subscriber and makes it easier to connect to the provider’s equipment.

How to connect a cable to a computer or laptop

Even an unprepared user can independently connect an Internet cable to the network adapter connector of a computer. For connection, a standard cable (twisted pair) with crimped RJ-45 connectors at both ends of the cable is used.

READ  How to connect a laptop to a car battery

You can connect the cable as follows:

  • Prepare a network cable of the required length.
  • Connect one connector to any LAN port on the router.

First, connect the cable connector to any LAN port of the router.

Now you need to connect the second connector of the cable to the LAN-connector of the computer.

In old type modems, the provider’s cable should be connected to the yellow connector on the modem.

The connecting cable from the device must be connected to the Ethernet port of the modem

When connected to a computer, the indicator LED on the router will light up

Connecting the cable is not a big deal, since all connectors have connectors that fit only the corresponding sockets on the computer’s connector panel. Making mistakes in this process is extremely difficult, even for a novice user.

How to create a dynamic connection

To correctly create a dynamic connection, you must perform a number of sequential steps:

  • Right-click on the Start icon.
  • In the menu that appears, click on the line “Network Connections”.

From the Start key menu, go to the Network Connections section

In the “Options” go to the option “Configure adapter parameters”

In the drop-down menu of the Ethernet connection select “Properties”

In the properties panel, select the line IP version 4 (TCP / IPv4), and then open the “Properties”

At the last step, activate the “Obtain an IP address automatically” and “Obtain DNS server address automatically” switches

The dynamic connection is now ready for use.

Ways to troubleshoot wired internet connection problems

When connecting the wired Internet, errors periodically occur due to equipment malfunctions, a break in the backbone network, or improper user actions. In most cases, connection problems arise due to the careless actions of the user himself. To determine and fix the cause of the problem, you need to follow simple steps according to the following algorithm:

  • Launch “Network and Sharing Center”.
  • In the “Network Connections” tab, select “Troubleshoot”.

Go to the “Network and Sharing Center” and open the “Troubleshoot” section

For further settings, select the “Internet Connections” option

You will see a highlighted line “Run the troubleshooter”, click on it to continue

Wait for the problem detection process to complete

Select “Troubleshoot Internet Connection Problems” and wait for the diagnostic process to complete

Select “Inbound Connections” to continue troubleshooting

Run the troubleshooter by clicking on the appropriate line

Check the box “Find this computer on the network” and continue troubleshooting using the “Next” button

Wait for the end of the network gateway configuration check

This completes the check of incoming connections.

The following instruction shows the detection of one inbound connection problem. details about the problem can be found by clicking on the line “View additional information”.

Next, let’s check the network adapter:

    In the “Troubleshoot” section, select “Network adapter” and click on the highlighted line “Run the troubleshooter”.

To start checking your network adapter, select the Run the troubleshooter option in the Troubleshoot section

In the list of adapters for diagnostics, check the Ethernet item

The given method of searching for connection errors is a classic one and was developed by Microsoft Corporation specialists. In reality, everything can be much simpler, since the problem with the Internet connection can be caused by other reasons, which are eliminated mechanically.

This algorithm helps to fix the problem with no internet connection in most cases:

  • Reboot your computer.
  • Disconnect the router from the network and wait 10-15 seconds.
  • Turn on the router.
  • If the connection is not restored, click on the Reset button to reboot the router.

To avoid problems with the Internet connection, it is recommended to periodically disconnect the router from the network and give it time to recover.

How to set up PPPoE connection in Windows 10

Internet Protocol PPPoE is used when connecting to the backbone network using Ethernet technology. This method has a number of advantages, for example, an expanded range of additional capabilities, compression of information during transmission, carrying out authentication and encryption operations with information packets. Connection requires authorization on the network (username and password). Used with direct connection to the backbone network and provider equipment.

To connect to the Internet using the PPPoE protocol, you need to perform a number of operations:

How To Share internet From PC to Laptop | Without Any Software

  • Open “Network and Sharing Center”.
  • Here select “Create and configure a new connection or network”.

In the “Network and Sharing Center” section, click on “Create and configure a new connection or network”

Select the first item. “Internet connection” and click “Next” for further settings

In the “Internet Connection” select the “High Speed ​​(with PPPoE)” connection

Enter the login and password received from the provider and click “Connect” to complete the setup

You now have a PPPoE connection.

Dynamic and static internet connection

After connecting the cable connectors and building the connection between the computer’s network adapter and the provider’s equipment, you can debug the Internet connection. First of all, it is necessary to choose a method of connecting to the backbone network, starting from specific goals. There are 2 ways to connect:

  • dynamic connection is a method in which an individual IP address assigned to a computer is automatically configured and changed when the initial parameters are transformed. The provider’s equipment independently assigns the values ​​of the network address and the default gateway to the computer. When the computer is connected to the trunk line, the connection to the global network occurs immediately, without requiring additional input of identification data from the user. The only inconvenience with such a connection is the possible representation of a remote connection to its own address. In this case, you must first connect to the trunk line directly, bypassing the router;
  • a static connection is a method of connection when the individual IP address provided to the computer remains constant and is indicated when concluding an agreement with the provider company. During such a connection, the user sets the address manually, and also independently prescribes the values ​​of the default gateway and DNS servers. If such information is absent in the contract, then you can find it out in the technical support department of the provider company. Some ISPs may require a username and password for online licensing. This information, as a rule, is indicated in contract documents or is determined by the subscriber independently.

How to connect the Internet on a computer from a Nokia phone using it as a modem.

Let’s see how to connect the Internet to a Nokia phone on a computer using the phone as a modem. If you want to know how to distribute the Internet from Nokia to another phone, tablet, laptop, computer or other device via Wi-Fi without wires, then below you will find a link to detailed instructions. To connect the Internet from a phone to a computer or laptop, you must first connect the phone to the computer via a USB cable, for this, the Nokia PC Suite program must be installed on your PC and we will establish an Internet connection using the phone as a modem. If you have this program installed on your computer, then we can start connecting, but if you do not have this program, then first you need to install it. Usually a disc with the Nokia PC Suite program is included with the purchase of a Nokia mobile phone, if not, you can ask your friends or download the program for free from the official website using the link to download the Nokia PC Suite program. If you do not know how to install Nokia PC Suite on your computer, follow this link to install Nokia PC Suite on your computer.

connect, internet, laptop, computer

1) The first step is to connect the Internet on a computer via a phone modem. Open the installed Nokia PC Suite program by clicking on the program shortcut. The program window will open, where we select the model from which we want to connect to the Internet, this is if you have several mobile phones connected at once and select the connection icon, look at the attached image.

2) Step two. In a new window of the program, an automatic connection to the Internet starts using the connected Nokia phone as a modem. Establishing an Internet connection from your phone starts automatically after 10 seconds, if you don’t want to wait, you can click on the Internet connection button at the bottom of the window in the middle. Usually, the computer itself detects the operator’s network and establishes the connection automatically and does not require additional settings.

3) If, nevertheless, the program could not independently determine the network of the telephone operator, then you need to configure the network yourself to connect to the Internet. To do this, click on the settings button, which is indicated by a key as shown in the picture above. In a new window, select the model of the connected phone and confirm with the arrow button as shown in the attached picture.

4) Choose your mobile operator from which we establish an Internet connection. In this example, this is MTS Russian Federation and you choose your network operator. Next, confirm with a tick button and the Internet connection on your computer automatically starts.

8) After a successful connection to the Internet on the computer, the taskbar will display a message that the phone’s modem is now connected, there you can also see the current Internet speed by clicking on the icon.

This is how the Internet is usually connected from a Nokia phone or smartphone, using it as a modem. The data transfer speed depends on your cellular operator and is different in different places, you can try other operators to connect the Internet to your computer and choose a faster Internet. Also, a weak Internet speed can be due to how your phone or smartphone is configured, try to select 3G, 4G, 5G networks or mixed mode in the settings. Now I have a 3.5G internet connection speed from my phone. 4G at this speed, you can already watch movies of good quality, and the Internet speed from your phone is only growing every year.

using a router

And so, as I said above, this method will be relevant if your laptops are connected to a Wi-Fi network, the computer is connected to the router with a cable.

There are no problems with access (i.e. there are no triangles with exclamation marks or red crosses on the network icon).

Note: I will assume that Windows 10 is installed on both PCs and laptops (in principle, with Windows 7/8, almost all actions are the same).


Now everything is ready, and you can start sharing (sharing) folders and disks. Let’s say you decide to make the “D: \” drive publicly accessible to all computers on your local network. For this:

  • first go to “My Computer” and open the properties of the disk;
  • in the “Access” tab, click on the advanced settings button;
  • then check the box “Share this folder” and save the settings;
  • note that several people will appear on the disk icon (i.e. it has become public).

Connecting laptop to PC


Well, the final touch. How to find now all those folders and drives that have been shared?

It’s very simple: just open the explorer and click on the “Network” tab. it will display all PCs and laptops in the local network (which are currently turned on).

By clicking on any of them, you will see which folders and drives it has publicly available (in my example, only the “D: \” drive is shared). By going into this folder. you will be able to work with files in the usual way. ✌


The first thing to do is to check the PC names and workgroups (on all laptops and computers between which you plan to exchange files, network games, etc.).

  • PC name. should be different on all computers;
  • working group. on all computers the same!

This can be done through the control panel: the “System and Security \ System” tab (or open the properties in “my computer”).

Note: after changing the working group. reboot device.


Next, you need to open network connections: click WinR. and use the ncpa.cpl command (universal method for different OS versions).

ncpa.cpl. View all network connections

Among the network connections, you must have (at least one) named Ethernet (this is the adapter to which we connected the network cable). It is necessary to open its properties (by the way, no crosses should be lit on it).

Then go to the properties of “IP version 4” and set the following parameters:

  • IP address:
  • Subnet mask:

On the second computer (laptop) also open Network Connections, Ethernet Properties. Only now it is necessary to specify a few different parameters:

  • IP address:
  • subnet mask:
  • default gateway and preferred DNS:


Then you need to go to the Windows control panel in the tab: “Network and Internet \ Network and Sharing Center” and click on the link to change additional. sharing options. See screenshot below.

Next, you need to enable network discovery, share printers and files, and disable password protection (by default, Windows 10 prohibits everything!). over, you need to do this for three profiles: private, guest, all networks.

Of course, such network parameters must be set on each of the laptops and PCs on the network.

Checking the created link

In theory, after these settings, the connection between the computer and the laptop should be established. Let’s check if this is the case and ping the network. To do this, press the WinR key combination on the PC and write the cmd command in the window that opens.

In the command line, enter the ping command (the ip-address of the laptop that we indicated above). If there is no packet loss and you get normal responses, then everything is fine:

Also, go to the “Network and Sharing Center” again and in the left column click on the item “Change advanced sharing settings”

There, in the “Home or Work” section, turn on all the parameters, as shown in the screenshot:

And also disable password-protected sharing. If this is not done, then in this case you will not be able to connect the computer to the laptop, where there are accounts with passwords on the Windows operating system (How to set a password on Windows 7).

We create shared access

After all this is done, you cannot just drag and drop information from laptop to computer and vice versa. To do this, you need to open shared access to hard disk partitions or individual folders.

To folder

To open public access to the folder, right-click on it, select “Shared Access. Specific Users”:

Add all users and click on the “Share” button. If you want the information to be changed in this folder from another computer, then we set all users the “Read and Write” rights.

We are given a message that the folder is open for public access:

We do all the manipulations described above both on a computer and on a laptop (I will repeat myself).

How to connect laptop to computer

In today’s article, we will consider a situation when we will need to connect a laptop and a PC for an equivalent exchange of information. In principle, a laptop is the same computer, so we just need to create a network between two computers, but more on that later.

First, I would like to say that a laptop is not a USB flash drive and you just can’t plug it into a USB connector, we will have to make a full-fledged network. So let’s get started.

Connecting two devices

The first thing you need is an Internet cable (twisted pair) crimped on both sides, it looks like this:

Now we find the network card connector on the back of the computer:

And a similar connector on the back of the laptop:

We connect two network cards with a cable and go to the settings of the Windows operating system.

To hard disk partition

To open access to a hard disk partition, you need to right-click on it and select the item “Sharing. Advanced settings” from the drop-down list:

In the “Access” tab, click on the “Advanced settings”

We put a bird next to the item “Share this folder”. If you want full access to this disk from another computer with the ability to change information, you can additionally click on the “Permissions” button and put the checkbox in front of “Full access”. And in the main window, click on the “Apply” button and click “OK”.

Look, now the icon of our section has changed slightly, two people have appeared next to it. This means that public access is open.

OS customization

In order to connect a laptop to a computer correctly, you need to make sure that these devices have different names, different ip-addresses and one workgroup.

In order to change the name of the computer and the workgroup, go to “Start” and right-click on the item “Computer”. from the drop-down menu, select the item “Properties”

In the window that opens, on the left, select the item “Additional system parameters”:

In the window that opens, in the “Computer name” tab, click on the “Change” button:

If necessary, change the name of the computer and workgroup:

Now let’s take a look at ip-addresses and other network settings. Everything that I will describe will need to be done both on a computer and on a laptop.

Right-click on the network status icon (near the clock) and select “Network and Sharing Center”.

Next, in the left column of the window that opens, select “Change adapter parameters”:

We are looking for our local network connection and right-click on it, select “Properties”.

We are looking for the component “Internet Protocol Version 4” in the list. select it and click on the “Properties” button

We put the switch in the position “Use the following IP-address” and enter the IP-address. and the subnet mask is We enter this for the computer:

For a laptop, we just put a slightly different address: the subnet mask remains the same:

How to distribute the Internet from a laptop connected via Wi-Fi via a network cable? Configuring a network bridge

Hello friends! Today I needed to connect a regular desktop computer to the Internet in order to update the antivirus on it. It doesn’t have Wi-Fi, and it’s very difficult to connect a network cable directly to the router, it’s just that the router is not installed in a very convenient place. And my laptop is connected to the Internet via Wi-Fi and I decided to try to connect a stationary computer to a laptop via a network cable and use a network bridge to distribute the Internet to the computer through the laptop.

Everything is somehow confused :). But now everything will become clear. I thought that maybe not only I may have such a situation and my advice may be useful to someone else.

This means that I had Internet on my laptop, which I received via Wi-Fi. The task was as follows: connect a stationary computer with a laptop via a network cable and make it so that the computer and laptop have access to the Internet, and not just a network.

Configuring a network bridge

The laptop has the Internet. We connect the computer to the laptop using a network cable (for how to crimp a network cable, see the article How to properly crimp an RJ-45 network cable). On the computer, the Internet connection status will be a network without Internet access. We need to make sure that there is access to the Internet.

To do this, go to Control Panel. Network and Internet. Network and Sharing Center (or right-click on the Internet connection status in the tray and select “Network and Sharing Center”). Then on the right select “Change adapter settings”.

Hold down the Ctrl key and select two connections. I have this Wireless Network Connection (through which the laptop is connected to the Internet) and Local Area Connection (this connection is used to connect the computer to the laptop via a cable).

Select these two connections and right-click on one of them. Select “Bridge Configuration”.

We are waiting a little while the bridge settings are created and we have a new “Network Bridge” connection. And two connections, wireless and LAN connection should get the status “Connected, Connected”.

If, during the creation of the Network Bridge, a message appears that it is impossible to continue because one of the connections is configured to share the Internet, then do this:

Right click on one of the two connections and select Properties. Then go to the “Access” tab and see that there is no checkmark next to “Allow other network users to connect to the Internet” If this checkbox is checked, then remove it. Also check another connection.

On a computer that is connected to a laptop via a network cable, the Internet should appear, at least everything worked for me. I updated the antivirus on my computer and I no longer need the Network Bridge. If you also want to delete the Network Bridge, then just right-click on it and select “Delete”.

If you encounter problems during setup and connection, try disabling your antivirus. Very often they block all kinds of connections.

That’s all I wanted to tell you in this article. Perhaps my advice is useful to you.
