If you want to know what WAN is, or how WAN differs from LAN, then you have come to the right place. Now we will try to figure out what kind of technology, connectors, connections, what they are for and what is the difference.
I think that in most cases, when someone is looking for information on the WAN, he means the connector on the Wi-Fi router. Indeed, in almost every instruction for setting up a router, you can find this abbreviation. Everyone writes about connecting some cables to WAN connectors, or LAN. Let's go in order:
WAN(Wide Area Network) is the global computer network. Simply put, it's the internet. If we talk about the WAN connector, then this is the connector on the router into which the cable from the provider is connected. Network cable through which the router accesses the Internet.
On almost all routers, this is a blue connector, and it looks like this:
The photo above shows that the connector is even signed. Also, on the router, as a rule, there is an indicator of the connected WAN cable. At normal operation, it should flash actively. And near the indicator itself, they usually draw an icon in the form of a planet.
Now you know what WAN is. Let's see how it differs from LAN.
What is the difference between a WAN connector and a LAN connector?
Here, too, everything is very simple. What is LAN?
LAN(Local Area Network) is the local network. Simply put, these are computers that are not very interconnected. long distance. For example, computers, televisions, mobile devices, which are interconnected through a router within the home or office. This is the local network.
On routers, you can usually find 4 LAN connectors. They are yellow and look like this:
They serve to connect devices to the local network via a network cable.
The difference between WAN and LAN is that WAN is access to the Internet, and LAN is a local area network to which devices that are close to each other can be connected.
I think that's all you need to know about these two designations. You can, of course, delve into technical points, abstruse definitions, etc., but this is unlikely to be of interest to anyone.
A router is a network device designed to distribute the Internet to several computers or laptops connected to it by cable or via wireless connection WiFi
Before using the router, you need it correctly
You can find the prices for setting up network equipment in the section ""
For additional instructions and options for solving problems related to poor Internet performance, you can get from the section
This port, depending on the router model, is used to connect:
Storage media (flash drive or NAS)
3G/4G modem for Internet distribution
Printer

Please note that the router can only have one of two types of ports for the ISP cable - WAN(Ethernet cable with connector) or DSL(telephone cable with connector). A router with a DSL connector is suitable for use only with a provider that provides Internet via. Routers with a connector for a connector are suitable for providers that offer Internet services over a dedicated line (Ethernet)
Do not confuse it with a telephone cable
RJ-45 connector is 2mm wider than RJ-12
One of the main criteria when choosing a router is the type of cable through which the Internet is connected to your apartment or office. It is this cable that needs to be connected to the WAN / Internet (or DSL) port of the router. There are mainly two types of wired Internet connection: two-wire telephone cable and leased line (category 5e or 6 twisted-pair cable)
On a computer or laptop with an operating Windows system press Win + R, in the "Open" field, enter the command " ping 8.8.8.8 -t" without quotes (this is the address Google DNS servers), then press OK. If there is an Internet connection, then in the console window you will see lines with . Readings are measured and displayed every second
If there is no Internet connection yet, you can ping the router itself with the command " ping 192.168.1.1 -t". The address of your router can be pumped to the other two octets: 192.168. 0.1 ... 192.168.10.1 ... 192.168.100.1 ... 192.168.1.254
You can find the address of the router in the settings network card- this is discussed in
As you move away from the source wifi signal or when the interference pattern between the laptop and the router changes, the ping will change
At a large distance from the router, the PING console command will issue lines with errors "Interval exceeded ...", "Transmission failure", "General Failure" and others
To use the LAN port as a WAN, it is not necessary to sit at the manual or flash the ADSL modem, losing the warranty. Meanwhile, we have a backup channel that can be used for important tasks that do not suffer network outages.
What could it be useful for? It's no secret that ISPs are suspicious of large traffic generation, especially if it refers to "mail" (smtp, pop3). Sending sms over the Internet can also fall into the "spam" category. Even when the router is rebooted (changing the IP address), it does not guarantee blocking by the provider. Therefore, the second channel will come in handy here.
If you decide to change your provider, leave Rostelecom for TTK. Both providers do not give out equipment for free now - you will need an additional router to work with TTK, because. A standard ADSL modem does not have an RJ-45 WAN interface. You have two options - either buy a router, such as DIR 300 or 620, or reconfigure one of the four LAN ports in the WAN direction. Our method differs in that we will not use special firmware, such as DD-WRT or OpenWRT, but will perform all the steps on standard firmware(on the example of Dlink 2640 nru)
old firmware
We go into the modem settings. At 192.168.1.1. Finding an item "Additionally" and choose "Interface grouping". In step Ethernet WAN port put a dot on the port that we want to use for the WAN connection, for example, LAN1:
For some modems, the top menu is in the left column - they are identical:
Now you need to configure this WAN port. Let's say your provider uses PPPoE authorization (by login and password). This is how it works, for example TTK. To do this, go to the "Network" tab and select "WAN". Click the "Add" button:
Name WAN PPPoE
Connection type- PPPoE
Physical interfaceโ LAN1
PPP usernameโ Here write your login to access the Internet
Without authorization - there should NOT be a checkmark
Password- your password for accessing the Internet
Password confirmation- repeat password
MTU โ 1492
The rest of the settings remain as default!
Now plug your ethernet cable into LAN1 and you're good to go.
New firmware
Switch the wire from the modem to the computer to LAN2 before starting the settings!. Go to Advanced settings:
Below (scroll with the mouse if not visible) in the menu, check the box "Make WAN-ohm":
All questions write in the comments.
I noticed that in the comments to various articles on the site, they ask questions about WiFi connection routers to regular ADSL modems. Many people have problems setting up such a connection. But, there is nothing difficult. In this article, we will consider the connection diagram and configuration of the ADSL modem + router bundle. We will connect normally network cable. Which you can buy, or take the one that comes with the router / modem.
Why connect two similar devices at all? If you have ADSL Internet, then it is clear that there is a modem. Many modems don't have the ability to distribute Wi-Fi, and we need Wi-Fi, it's hard without it now ๐
So, there are two options:
- Buy a new ADSL modem that has the ability to distribute the Internet via wireless technology. There are many such devices on the market today. If you don't want to make a choice, then call (or go) to your Internet provider, and he will advise you on a specific model and manufacturer. Or offer your device. Many providers have network equipment that they seem to recommend using.
- And the second option (which this article will be about). You can buy a regular Wi-Fi router, any, and connect it via a network cable to a modem. The modem definitely has network outputs (LAN). The router will simply take the Internet from the modem and distribute it over the air.
As you can see, everything is very simple. We need the modem itself (which should already be configured and distribute the Internet), network cable (which is included with the router), and the Wi-Fi router itself. Now we will connect and configure all this.
By the way, we already have a similar article on . You can view.
We connect the router to the ADSL modem
before connection, necessarily do it on a wifi router. Even if it is new, from the store.
Next, take the network cable. One end is connected to the modem in LAN connector (it is usually signed and highlighted in yellow). Your modem may have several LAN connectors. You can connect to any
We connect the second end on the router in blue WAN connector. Watch carefully.
That's actually the whole connection diagram. If you reset the settings on the router, and your modem distributes IP automatically, then the router should already distribute the Internet via Wi-Fi. And by cable, to the router, you can connect the devices that you had connected to the modem. Here are the instructions just in case.
Router settings
If it doesn't work automatically, then let's check the settings. We will only configure the router, we do not touch the modem. But, your modem must be configured, and the Internet must work through it.
You need to check if the router settings are set to automatically obtain an IP address. Provided that the modem distributes IP automatically.
Go to your router settings. If you don't know how, then.
Go to the tab WAN. Depending on the brand and model, this tab may be called differently. Internet, network, etc.
And see what would be in the field WAN Connection Type (Type of WAN connection) was found Dynamic IP (Dynamic IP address). Set and save settings. This is on the example of TP-Link.
