When do i use the wan port

A wide area network usually traverses multiple geographical areas. The internet is the most prominent example of the WAN network type, though other wide area networks exist for scientific purposes, military and government work and to connect far flung offices and data centers within some big corporations. In all homes and most small businesses, the WAN port connects to a high-speed modem, like a DSL or cable modem, which in turn connects the router to the Internet.

Once connected, these computers can access the Internet and other computers on the LAN, just like those that use Wi-Fi. While modern routers are designed to connect computers and other devices wirelessly, they often have some physical ports on them as well where computers can connect directly, often using Ethernet cables.

They usually use an Ethernet cable to connect to a modem you receive from your internet service provider. In some cases, a router may also be a modem, in which case it may connect to a cable line or phone jack instead. Modems are for connecting to a specific type of broadband Internet service, usually either over phone line DSL or cable or increasingly, fibre optic cable. On a home broadband router, the DSL port is for connecting your Internet service to your home through a phone line as opposed to a coaxial cable line for cable Internet service.

Some routers have both a built-in modem and a WAN port; the WAN port in this case is provided so that you can use the router with an external modem instead of the built-in one not usually at the same time. This is useful if you change your broadband service in the future to one requiring a different modem, and you still want to continue using the same router. If you are extending your Internet service from your modem to a router, plug the Ethernet cable from your modem into the WAN port of your router.

So, a WAN cable is the same as an Ethernet cable, but to improve your network performance, choose the minimum Cat5e cable or Cat6 length required to connect your modem to your router. In this setup of two routers, the WAN port is for connecting your second router to a LAN port of the main router, switch, or modem.

Think of a Wi-Fi client as a device that has an invisible network port and an invisible network cable. This metaphorical cable is as long as the range of a Wi-Fi signal broadcast by an access point. 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. You can check this by looking at your settings in your PS4 to see if it received a private IP address. You can also check your SR settings as well, and you should see all the devices connected to it. If the IP address is one of the following ranges, then you have nothing to worry about: I use the google wifi system and they only have one port which is connected to my modem.

Great question. From my understanding of the mesh Google WiFi routers, each node should have 2 ethernet ports on them that both look the same, according to the most recent versions I have seen.

I am not sure if they ever came out with a version that only ever had one port, but I usually have seen two as the minimum. How old is your Google WiFi router? Does the bottom of yours look like this? If so, you will just need another internet cord to plug into your work laptop, and into the open port on the Google WiFi router, and it should work. I can already do this by usb tethering my smart phone to my linux pc then I can surf the net from my single pc. I understand the first step is to run an ethernet cable from my tethered pc to my router using the WAN point.

I believe the next step is to set up a a dhcp server on my linux pc. Then somehow I need the incoming ip address from the phone to be translated to an outgoing address for the router. I am a programmer not a network engineer and looking at my linux pc I cannot quite figure out what to do. I have set up 2 linux networks one restricted to the usb port the other restricted to the WAN port — eth0 — on the router. I found an opportunity to set up a third network called shared.

But there are too many options such as shared, local link, etc etc to know what to select. Combined with not knowing how to get the various addresses out of phone, pc and router and relating them to each other it makes for far to many unknowns.

Can you give me a description using addresses for selecting static or automatic addresses and relate them to my 3 designated networks in linux mint. This all came about because I wanted to set up a NAS based on a raspberry pi but all the tutorials seem to presume the LAN is already connected to the internet. Is that feasible? Personally, I come from a programming background as well, and only as of recently moved into IT Infrastructure and Information Security to really understand how the apps built by us programmers reside in an IT environment, its been quite enlightening.

First, I would probably hesitate to use your computer as a means to handle all of your public traffic. If its just for on demand instances, then this should suffice as a stop gap.

Then you will just need an easy firewall rule likely using iptables, depending on your flavor of linux , and just write a rule that forwards all incoming traffic to the raspberry pi, to the network interface that the internet is connected to whatever that interface name is on the raspberry pi.

That should then just about do it, and you can certainly find that rule on line doing a quick google search. Now this is if your raspberry pi is handling everything.

If it doesnt, and you want to use a router as you have mentioned, the same as above applies, but it will have to be done on your Linux Mint PC. In regards to the networks you have set up, I am not sure what those are in particular, but those networks will have to forward all of their outbound traffic onto the usb network interface that is connected to the internet, with the same commands as above, but three rules, one per your network.

As with your NAS, that should be easy enough to set up on your raspberry pi. Because if so, you will need to see if the USB tethering doesnt block all incoming connections as the phone itself might be a firewall and router and provide you internet access, but only outbound connections, and likely not let you configure incoming connections. This is why a dedicated device would be better, but also not USB tethered, but rather running on a 4G modem. As for your last scenario, I am not too aware of what owncloud is, but if you are just looking for networking area storage, any network connected device that has network file sharing capabilities, like samba, or ntfs, should work just fine, and might not need a whole LAMP stack to accomplish that.

I know I mentioned a lot above, but if I can get your use case down really well, we can come up with a configuration that suits your needs. I have a pace modem that has a built in router. For whatever reason, the ISP is telling me their modem needs to be bridged to another router I have a netgear AC Router in order to access the internet.

So not sure what type of connection this is.
