The router asserts the unique public IP address your Internet Service Provider assigns to you and it offers security features such as a firewall with port forwarding and quality of service, which prioritizes Internet traffic. WAN port is used to connect with a modem for Internet source while LAN port is utilized to share that Internet connection with all devices associated to routers such as a computer, printer, and mobile phones.
The user needs to know what is the difference between these ports while connecting a home router to the Internet. Remember that a LAN socket is needed to connect computers if there are several, and the WAN is needed to connect with the modem which allows you to receive a signal from the Internet provider. Also, the ports differ in the data transfer rate. The speed of data transfer in a local network is often higher than the speed of downloading data from the Internet.
This can be both because of a limitation in the levy plan from the provider, and due to the limitations of the connector itself. Therefore, devices can exchange data via Wi-Fi with each other at a high speed, provided that the network cards of the devices support this speed. LAN port is used to provide Internet access or files sharing facility to all the connected devices.
WAN port is used to provide Internet access by connecting with a modem or wireless broadband to all the connected routers. Networking Devices. In general, a modem has a LAN port for connecting to the WAN port of a router and a service-related port, such as a coaxial port cable modems or a telephone port DSL modems which connects to the service line.
If you only have the modem, only an Ethernet-ready device, such as a computer, will be able to connect to the Internet. To connect more than one device to the Internet, you will need a router. Some providers offer a combo device, which is a combination of a modem and a router, or wireless router, all in one.
The LAN ports on the modem are intended for connecting to a local network, but they can always be made WAN, in the modem settings, if necessary. It is used to connect to your modem which in turn allows you to connect to the Internet.
Unless you access the Internet via a telephone link, without a WAN connection there will be no Internet connectivity. LAN and WAN ports are found on the back of your router, so it is important to know the difference between the two so you can plug the correct cables into the correct ports.
On a typical router, you will see usually four LAN marked ports and one WAN marked port, although without these labels the ports will look identical unless they are colored differently. LAN is the abbreviation for Local Area Network and is essentially a group of devices connected to each other over your home network. In your home, every device connected to the Internet via your router is part of your LAN. Devices connected over a LAN allow the sharing of resources such as files or printers, but also allow connectivity to each other.
A good example of this is having a networked printer connected to your LAN which allows any of your print-enabled devices to print directly to it. Ask your neighbor to print to it, however, and they will quickly find they are unable to do so due to not being connected to your LAN. Unless you decided to share your Wi-Fi password with them, of course. WANs are a little bit more complicated in that they can be both private or public, but are easy to understand when you think of a few examples.
A good way to understand how a private WAN works would be to think of a large corporation with many offices spread out from each other. As a side note, as a WAN connects LANs together over the Internet, safeguards need to be put in place by corporations to prevent any unauthorized access to their networks.
Note: The type of Wi-Fi connection mentioned above is established in the Infrastructure mode , which is the most popular mode in real-life usage. Technically, you can skip an access point and make two Wi-Fi clients connect directly to each other, in the Adhoc mode. However, as with using a crossover network cable, this is rather complicated and inefficient.
Wi-Fi range: This is the radius an access point's Wi-Fi signal can reach. Typically, a good Wi-Fi network is most viable within about feet from the access point. This distance, however, changes based on the power of the devices involved, the environment and most importantly the Wi-Fi standard.
The Wi-Fi standard also determines how fast a wireless connection can be and is the reason Wi-Fi gets complicated and confusing, especially when considering the fact there are multiple Wi-Fi frequency bands.
Frequency bands: These bands are the radio frequencies used by the Wi-Fi standards: 2. The 2. Generally, the 5 Ghz band delivers faster data rates but a little less range than the 2. Note that a 60 GHz band is also used but only by the Depending on the standard, some Wi-Fi devices use either the 2. Wi-Fi standards decide the speed and range of a Wi-Fi network. Generally later standards are backward compatible with earlier ones. It offers a top speed of 11 Mbps and operates only on the 2.
The standard was first available in and is now totally obsolete; It's also now obsolete, though it's still supported by new access points for backward compatibility. The standard offers the top speed of 54 Mbps but operates on the 2. It's used by many older mobile devices, such as the iPhone 3G and the iPhone 3Gs. This standard is supported by access points of later standards. The standard operates on both 2.
There are two types of dual-band routers: selectable dual-band routers now defunct that can operate in one band at a time and true dual-band routers that simultaneously transmit Wi-Fi signals on both bands. On each band, the Wireless-N standard is available in three setups, depending on the number of spatial streams being used: single-stream 1x1 , dual-stream 2x2 and three-stream 3x3 , offering cap speeds of Mbps, Mbps and Mbps, respectively.
This in turns creates three types of true dual-band routers: N each of the two bands offers a Mbps speed cap , N one band has a Mbps speed cap while the other caps at Mbps and N each of the two bands allows up to Mbps cap speed.
Note: In order to create a Wi-Fi connection, both the access point router and the client need to operate on the same frequency band. For example, a 2. Also, a Wi-Fi connection takes place on just one band at a time. If you have a dual-band capable client such as the iPhone 6 with a dual-band router, the two will connect on just one band, likely the 5 Ghz.
The standard also comes with the 3x3, 2x2, 1x1 setups that cap at 1, Mbps, Mbps and Mbps, respectively. Technically, each spatial stream of the In real-world testing so far, with the same amount of streams, I've found that Note that the real-world sustained speeds of wireless standards are always much lower than the theoretical speed cap.
This is partly because the cap speed is determined in controlled, interference-free environments. The fastest peak real-world speed of an On the same 5 GHz band, While That said, all Prior to that, it was considered a different type of wireless networking.
Operating in the 60 Ghz frequency band, the It can't penetrate walls very well, either. For this reason, the new standard is a supplement to the existing It's an ideal wireless solution for devices at a close range, with a clear line of sight no obstacles in between such as between a laptop and its base-station, or a set-top box and a big screen TV. All Like However, it's the first standard that focuses not only on faster speed but also on Wi-Fi efficiency, especially in crowded air space.
In other words, Ultimately, this means it allows for higher ratio of real-world speed versus theoretical ceiling speed. It's also said to reduce energy consumption by two thirds compared to On paper, For instance, the high-speed information comes to a single router, and that router then has connections from its LAN ports to three other routers where it plugs into their WAN ports.
These internal networks would contain independent information and have no more of a connection to one another than they have to a network in a different building. Please enter the following code:. Login: Forgot password?
