Just a few years ago, the LAN setup through the DIR 300 router in Windows 7 and Windows 8 could only be done by a specialist. Today, this simple, thanks to full automation, operation can be performed even by an inexperienced user. All that is needed for this is a computer, an accessible Internet and a router.
When a common communication channel can be used for several home devices, but there is only one wire, in this case the router is simply irreplaceable.
A router is a device with an individual power supply, when connected to it, each computer, regardless of quantity, gets free access to the Internet.
You can connect several devices to a router (router) simultaneously: an e-book, a smartphone, a set-top box, a laptop, a computer, and a tablet.
Connecting gadgets will provide each of them with access to the Internet and help the rapid exchange of information.
Connection for the router can be done in two ways:
It depends on the model of the router (availability of Wi-Fi) and the desire of the user. For example, setting up a local network through a dir 30 router is not a difficult job that even an inexperienced user can do.
Instructions for wired connection:
UTP network cable, if necessary, crimp correctly;
connect the router to the mains;
connect gadget cables to it;
configure network functions.
A connection through a router not only creates a network between several computers, but also protects them from some breakdowns (for example: provider cable wear, breaking this cable, lightning strikes).
A cable from the provider is inserted into the corresponding socket on the router. Then, the IP address of the user, the mask of the secondary network, the main gateway, two DNS servers (preferred and alternative) are registered in the settings of the router. Additionally, you can copy the MAC address of the network card, password and login to the network.
Basically, router models are equipped with four jacks for connecting. Each of them is carried out according to a single algorithm. Then you should check and configure network connections.
Checking physical connection
Having completed the necessary work, you should make sure that the switches and cables work correctly, that is, the presence of functional physical communication between the gadgets.
To do this, you need a ping utility that checks the stability of TCP / IP settings and tests other host connections. The process consists in sending packet data of a limited volume to the address specified in the settings.
According to the rules, upon receiving an information packet, each network device immediately sends a response. The communication line between the configurations is broken or missing if the answer does not arrive within a certain time.
Before using the ping utility, you should:
computers that are checked for connectivity must be turned on;
make Start / Run commands;
enter ping 127.0.0.1 command data, allowing to check the functionality of the utility itself;
the address in the command, replace with the address of the local computer, this will allow you to check the operation of the network card;
check the target computer (for example, ping 10.20.16.1), if the response is the line “Exceeded the waiting interval for the request”, then this is a confirmation of a malfunction of the switch or cable.
You can send a large number of packets to the network using the – t switch, separated by a space from the ping command.
How to configure a local network via a wi fi router
A Wi-Fi router is needed to combine two or more devices into one network, to open shared access to various folders, files, disks, and to exchange information.
Wi-Fi router connected to a virtual network with an automated IP and DNS system:
A computer with a wired Internet connection
a computer with an OS similar to the first, but with a Wi-Fi connection
Getting started through a wifi router in Windows 7
First, you should check the connection with the ping command. To do this, we find the router settings in the browser. We carry out in a few clicks the necessary transitions on the menu and search. If in the end, after pressing the "Enter" key, the exchange of packets between devices starts, then the connection works.
It is necessary to disable antivirus, Windows firewall and firewalls in case of the first network connection problems. After that, you can begin to configure the existing network.
After checking the working groups of gadgets, we set a name or change what must be done, if any. You should also cancel the password request.
The work is done, the network is configured. It remains to restart all computers.
LAN in Windows 7
In order to configure the adapter parameters (mask and IP), we perform the necessary actions, after which the entire range of Internet connections is displayed:
you should select one of them corresponding to the adapter of the connected computer;
in Properties we find “Internet Protocol Version 4 (TCP / IPv4)”, through which the connection is made;
then enter the IP address.
It should be noted that the last digit in it is the number of the device, that is, depending on how many of them are connected in a particular network, enter 1 for the first, 2 for the second, and so on.
The subnet mask is set automatically after pressing the "Subnet Mask" key.
Now all the gadgets connected to the network will appear in the Network menu, but access to each of them will occur relative to the settings specified in the "Network and Sharing Center."
To open sharing documents, on computer 1, select the desired folder and open properties in the properties. To allow content changes by other network users, access must be allowed again.
In the network environment of computer 2, we find all the computers that are in the workgroup and click on the link.
After these steps, a shared folder will be displayed on computer 1.
Two network routers
Sometimes you need to connect two routers. This can also be done independently.
First, prepare the network wire and decide what effect we want to get as a result of the actions: connecting existing local networks, a single Internet access point, connecting devices, wired and wirelessly, to a second router.
Using Wi-Fi or a network cable, you can connect two routers to the network.
When using a cable connection, one end is connected to the main unit (LAN), and the other is inserted into the second (WAN). Having received the necessary data about the request, we complete the work by checking the box for automatically receiving IP addresses in the second router.
Using a cableless data transmission network to connect routers, you just need to go into the settings of the second router and, starting a search on wireless networks, join the Wi-Fi network created by that time by the first device. Next, do the same steps as during a wired connection.
LAN in Windows 8
The new Windows 8 system makes it possible to watch movies, games, talk with friends, work in Office, search for your favorite applications in the specially created Windows Store right from the screen.
To configure, go:
in the Start menu, it is displayed on the gadget screen when Windows 8 starts up;
next, go to a few clicks go to connections, for Windows 8 it is Ethernet;
In the properties we find "Internet Protocol Version 4 TCP / IPv4";
open the General tab;
select "Obtain an IP address automatically" and "Obtain a DNS server automatically."
We agree with the “OK” button, and with this action we complete the configuration of the local Windows 8. OS network. You can check the connection and Internet access by simply clicking on the “Connection” icon.
It is striking that the configuration of the local network through the router windows 8 and earlier versions of the OS are similar. The only difference between them is the entrance to the settings. But users of the eight have already mastered this item using hot keys and a search engine. Having mastered the search for the control panel, the owner of Windows 8 performs all other actions similarly to previous versions.
Connection and verification
When connecting and configuring wireless communications, you should check the basic settings:
connection to the power supply network of the access point;
checking its functionality using other gadgets (device discovery, reports on its operation);
control the installation of drivers;
enable the network adapter if it is off;
Click the Internet access icon to check the network settings.
To provide shared access to a network printer on a local network, you should find the connected device in the “printers and faxes” folder located on the main PC. In the printer menu, we agree with the availability of the device for all computers and it will automatically be detected on all computers with a local connection.
For further use of equipment that is in single access from computers connected to a shared network, you must follow the steps of the connection wizard in the "printer setup" folder.
First, select the item that talks about the network printer, with a connection to another gadget;
secondly, it is necessary to review printers;
thirdly, if we are confident in the frequent or constant use of the equipment, we agree to use it by default.
After completing the settings, we connect the gadgets using network cards using the Network Bridge method.
