A local area network (in our context, a home network) is a group of interconnected computers, laptops, printers, TVs located within a house or room.
Benefits of using a local network:
- Access to shared network services.
A) unimpeded exchange of file resources over the network (no need to transfer a file (photo, music, movie) from one computer to another, using a USB drive, you can transfer it using a local home network).
B) Using a network printer. If you have a printer installed at home, you can use your home network to print from any computer/laptop to this printer.
C) Using the home network to build a play area. Many games support LAN play, and if you have one, you will be able to play games with computers on your LAN.
- All members of the local network can access the Internet (if configured). If you use Wi-Fi in building a home local network, then tablets and phones can also be connected to a local network and access the Internet from them.
A local home network can be created in various ways, I will give diagrams of the most popular of them, starting with the most primitive and ending with more complicated methods, with setting up the Internet on a local network.

Connecting two computers / laptops to a home local network using a network cable.

Let's analyze the easiest way to combine two computers into a home network (computer-computer or laptop computer). To do this, we need two computers / laptops and one network cable. Modern network cards are able to recognize what kind of crimp your network cable has, so you can crimp or buy a crimped cable Computer-Hub/Switch (straight crimp).

Schematically, the computer-to-computer connection looks like this:

The advantages of this method of creating a home network:

All you need to create a network is a cable and a clear head.

In this way, in most cases, only two computers / laptops can be connected, since most computers / laptops have one network card.

It is necessary to manually enter the IP address and mask on all computers / laptops on the home network.

Combining several computers / laptops into a home local network using Wi-Fi.

For this method, you need Wi-Fi on computers / laptops.

Wiring diagram:

The advantages of this method:

No wires

High workplace mobility

Combining network devices into a home local network using a switch (switch).

For this method, we need several computers / laptops, the same number of network cables and a switch (hub). The general connection scheme using a network switch looks like this:


Those. we connect one of the devices to each port of the switch (laptop, computer, printer or TV).
The advantages of this method:
- Ability to connect more than two computers / laptops to the local network (depends on the number of ports in the switch (switch))
Minuses:
- It is necessary to additionally buy a switch (switch), it costs about 500 rubles.
- You must manually enter the IP address and mask on all computers / laptops on the local network.

Connecting computers to a home local network using a router.

Using a router, you can set up a home local network with the Internet, if your router supports Wi-Fi wireless data transfer, then in addition to computers, laptops, printers, TVs, you can add tablets and phones to the local network.
Diagram of a home local network using a Wi-Fi router / router:


With this method of creating a local home network, you need to enable DHCP on the router - the service responsible for automatically distributing network settings (this function is enabled by default).
Advantages of creating a home network using a router:

It helps to combine various devices (computer, laptop, printer, tablet, smartphone) into one local network.

The ability to set up the Internet in your home network.

There is no need to manually write network settings on each device.

The need to purchase a router (from 1000 rubles) and its configuration.

There was a small problem, I got tired of constantly connecting the cable to the computer, choosing the flash drive mode on the phone. Despite the fact that I constantly throw files on the phone’s flash drive. I rushed to look for a solution, and this is what I found: fly: Now you don’t need to constantly connect the cable, but just turn it on wifi.
The article is written exclusively for owners of Android animals. Do not flood the topic !! Do not write "Wow, how cool" "Is it possible on my calculator?" etc. If you have any questions, write in the topic.

You must have an Android smartphone and your own home wifi router. for this method, it must be smart and the computer is on the same network (local). You can do it with an external one, via 3G or GPRS, but there will be a lot of traffic.

1. Installing SwiFTP

SwiFTP can be downloaded from the Android Market. This is a small application that runs its own FTP server on the phone. Access to the phone from remote networks through a proxy is also supported, but this will not be covered in this article. As stated in the description, any client can be used (such as FileZilla or Cyberduck), but we will use the functionality built into Windows.

2. Setting up SwiFTP

Once installed, open SwiFTP. Press the Setup button, the screen shown above will open. Fill in the empty fields with the data that you would like to use to connect to the phone from a computer. The port number can be left at the default 2121.

3. Start FTP server

Now return to the main screen and click Start. A line like ftp://192.168.X.Y:Z/ will appear next to the Wifi URL line. This is the address of the phone on the local network, followed by the port number of the FTP server.

Your phone is now ready for connections from computers on the local network.

4. Mounting a network drive


Open "My Computer" and select "Map Network Drive".

5. Connecting to a website

A window will appear for you to enter the drive letter and folder. Ignore them and click the link below to mount the Web drive.

6. Entering a phone address


Enter the Wifi URL from step 3, and click Next.

7. Entering a login


Now enter the login that you entered in step 2. Later, when you map a network drive, you will need to enter a password, which will then be saved so that you do not have to enter it every time you connect.

8. Final steps


Now enter the drive name as it will appear in Explorer. This is the final step, if everything is done correctly, then the phone will appear in the network drives of the computer. An FTP connection is a little slower than a USB connection, but you will save a lot of time by not having to turn off your phone and take out the card every time, or connect your phone via a cable. All you need to remember is to remember to run SwiFTP on your phone in order for the connection to be established.

It is displayed in "My Computer" here it is.

Important: If you write this when entering any folder (pictures below), then specify the path in the SwiFTP program not / sdcard but / mnt / sdcard.
Via Embedded Windows

Via FileZilla

Connecting Android to a local network

In this article, we will consider how to connect a phone or tablet to a computer's local network. This is useful even in cases where you do not have a local network, as such, but only a computer connected to a wireless network. The advantages of connecting to a local network are obvious - you will be able to access Windows files and folders right on your phone.

This is necessary, for example, when you need to watch a movie on your phone. To do this, it is not necessary to connect it to a computer, copy it to a phone, and so on. It is enough to view it by connecting to a local folder. Well, let's start setting up the phone's access to the local network.

First of all, you need to set up a local network on your computer, and set up access to certain files and folders that you will have access to in the future. This is done quite simply, for this it is enough to know how to set up a local network in Windows.

And in order to connect the phone to the local network, you need an application. Let's take the ES File Explorer application as an example. This is a fairly popular file manager program, and with its help you can really get local access to your computer. You can download it from the Play Market, there are no problems with this.

After installing the application, launch it and go to the network connection tab (at the top of the screen, you need to select the computer icon labeled LAN). Now, click the "Scan" button and search for local networks in the area of ​​​​your phone.

Another connection path can be done by manually creating it. That is, you will need to click on the "Create" button and configure the connection settings manually. In other words, knowing the parameters for connecting to your network, you manually make connections on your phone. To do this, you will need to know the IP of the computer, as well as set a password if you have set one on your local network. After that, the phone will connect to the local network and all folders and files open for access will become available to you.

That's all you need to know about connecting an Android phone to a Windows LAN. In fact, this is all much simpler than it might seem at first glance, in addition, other applications can be used for such a connection, but the example given is the easiest to implement.

If users think about distributing the Internet via Wi-Fi for their Android phone / tablet in the first place, then after a while there is a desire to transfer their files to a computer via the same Wi-Fi. This approach will allow you to get several advantages - quick access to remote media (including playback of audio / video files), and ... there is no need to use bluetooth or usb-cable!

In this guide, I will describe how to implement:
1) Connecting a mobile device to the hard drives of a Windows PC;
2) General principles for creating a home local area network (LAN).

Connecting an Android device to a LAN

So, here's what we need (typical set):

1. Mobile device (in my case Asus Nexus tablet);
2. Android App ES File Explorer;
3. The computer to whose hard drives we will connect;
4. The router to which the computer and Android device are connected;

It is assumed that your mobile device is already connected to the router via Wi-Fi, since this topic deserves a separate discussion, we will not consider it within the framework of this article.

LAN setup

Usually, when connecting through a router, there are no problems, everything happens automatically, dynamic IP addresses are issued for devices. But it is important that all your computers are in the same workgroup. How to do it?

Go to "Control Panel > System", look for the section "Computer name, domain name, workgroup name" and click "Change settings" and again "Change".

In the "Workgroup" field, write "WORKGROUP". Then click "OK" and restart your PC.

Go to "Control Panel > Network and Internet > Network and Sharing Center" and share folders.

If for some reason we get an error about the unavailability of the RPC server, then go to "Management (right-click on the "My Computer" icon")> Services and Applications" and start the services:

• Remote procedure call (RPC);
• Server;
• DCOM server process launcher;

We try to detect our PCs in EN Explorer, if it fails again, go to the next section.

Setting up IP addresses

If it is difficult to connect devices in the local network, it is recommended to enter the IP addresses of the devices manually. Occupation is tedious, but not difficult :)

1. We go on the computer to "Control Panel> Network and Internet> change the view to" Large icons "in the upper right corner> Network and Sharing Center> Change adapter settings".

We select our connection, my laptop is connected to the router via an Ethernet cable ("Local Area Connection"), so I configure it. Similarly, you can configure the "Wireless connection".

2. To simplify our task, right-click on the icon of our connection and select the "Status" item, in the window that opens, click the "Details" button.

We are interested in the current IP address of the computer and the main gateway. We will need them in the next paragraph. Leave this window open for now.

Today we will talk about a seemingly very banal topic, namely the local network.

The local network, LAN(slang. locale; English Local Area Network (LAN) - a computer network covering a relatively small area or group of buildings (home, office, company, institute).

Ask: “What is the connection between LAN and smartphones?”. Everything is very simple. When I bought my first Android-smartphone (HTC Wildfire), I was very interested in how this "smart guy" is able to tightly "communicate" with computers without the help of a synchronization cable, using only a Wi-Fi module.

Having studied it up and down, I noticed that the firmware is not adapted for a network environment. Only in later versions of Android did DLNA appear.

D digital L iving N work A lliance is a standard that allows compatible devices to transmit and receive various media content (images, music, video) over a home network, as well as display it in real time.

But I wanted to transfer not only music, but also documents and other files. And a huge thank you to the third party developers who came up with a cool android app that helped me make my dream come true, “ This app combines a file manager with its own archiver, media support and more and more. But her point is something else. Using “ES File Explorer” it is very easy and convenient to share files over the network and with cloud services (Google Drive, Sky Drive, Drop Box, etc.).

So, we need a computer (OS - Windows, Linux, possibly OS X), a smartphone (Android OS) and a shared Wi-Fi point (router).

Download the application “(it is free) from Google Play and install it on your smartphone.

At the top you see three tabs. By default, there are four of them, but I removed one (FTP), since I do not use this protocol. Let's talk about the LAN and "Network" tabs. Let's start with LAN.

When you click on the bookmark, we see the following picture:

Here I have added the computers that I use. To do this, click on the second button on the right (with a plus sign), and then a window will appear in which you will be prompted to create a server or scan the network environment. I note right away that the scanning process can be lengthy and not always effective. So select the "Server" item.

Here you are invited to specify the domain name (if you have a DNS server), the server IP address (for example, 192.168. in fact, enter the name of the connection (the name that you will display on your smartphone; it can be anything, for example, “Home computer”).

If you check the "Anonymous" box, it will look like this:

All you have to do is enter the computer's IP address and connection name, which is enough to exchange documents between your smartphone and PC. Now you need to share folders or drives on your computer.

Smartphone and PC must be on the same Wi-Fi network

Now we take a smartphone and go to our computer, select a folder or file, hold down the icon.

Now we select an action (for example, copy or cut) and go to the PDA tab.

Select the folder where you want to paste the file - and voila, you have it on your phone.

The same can be done with cloud servers. Select the "Network" tab.

We add the server in the same way as we added the computer, only here you will have to enter the credentials of your account in the cloud service.

After adding cloud servers, you can do the same file sharing steps as from a PC. You can also exchange directly between the cloud and a PC using a smartphone (without downloading information to it).

If you, unlike me, use an FTP server somewhere, then know that adding and configuring are similar. The only thing - check the correctness of the port, login and password (if required). It is much more interesting to get through the browser to the smartphone using FTP. To do this, go to the settings of the “ES-Explorer”.

Select the remote access settings (Root rights are not needed).

And we set everything up: we select the port (any one is possible, but let it be as it is) and the root folder (the folder into which the first entry will be made). Next, we set up accounts (this is if you want to restrict access to your smartphone), then set up the encoding (if the browser shows hieroglyphs), and a quick launch of the FTP server (creates a shortcut on the smartphone’s desktop). To get to your smartphone from a computer, you need to type ftp://192.168.0.102:3721 in your browser (just enter the IP address of your phone, it is listed in the “Remote Access” item).

P.S. And advice to students. If you have a Wi-Fi network deployed at your university, buy yourself a Wi-Fi adapter. This will greatly simplify the task of copying information.
