If you\u2019re reading this, then you\u2019ve probably come across the WAN connection down error. It\u2019s only natural to explore the internet for a fix before contacting support or a friend that\u2019s more tech-savvy than we are.<\/p>\r\n\r\n\r\n\r\n

This article is going to discuss what WAN (Wide Area Network)<\/a> is, how it works, why there\u2019s such an error<\/a>, and if there\u2019s a possibility of fixing it. Hopefully, after reading this, you\u2019ll understand what you can do to get everything working properly.<\/p>\r\n\r\n\r\n\r\n

What Is WAN?<\/h2>\r\n\r\n\r\n\r\n

In the network taxonomy, we have LAN (Local Area Network), WAN (Wide Area Network), and RAN (Regional Area Network). These are all different according to the areas they cover. LAN covers the local network, i.e. our home network.<\/p>\r\n\r\n\r\n\r\n

WAN covers a wider range, and it\u2019s a network that has a radius of more than half a mile. This is usually our entire neighborhood, or university campus, etc. Finally, RAN is something that\u2019s constructed by our ISP (Internet Service Provider).<\/p>\r\n\r\n\r\n\r\n

WAN can be considered a network of networks, and it\u2019s widely used by ISPs, universities, libraries, dormitories, etc. We can think of the Internet as a wide area network because it\u2019s a network that covers a lot of areas and almost every other network is connected to it.<\/p>\r\n\r\n\r\n\r\n

How Does WAN Work?<\/h2>\r\n\r\n\r\n\r\n

There are many ways we can establish a WAN connection, and there are several types, but the most common means to create a WAN network is packet switching. The method of forming data packets and transferring them through a digital network.<\/p>\r\n\r\n\r\n\r\n

The packet switching method is the primary method and the foundation of network communication. Data packets<\/a> are composed of two pieces, the one containing the routing information, the metadata (header), and the one that contains the data we see (payload).<\/p>\r\n\r\n\r\n\r\n

Now, to send and receive these data packets, we also have protocols on the network. The Wide Area Network uses the X.25 protocol, which is one of the oldest communication protocols.<\/p>\r\n\r\n\r\n\r\n

It\u2019s one protocol that is still used to operate hardware like POTS (Plain Old Telephone Service) and ISDN (Integrated Services Digital Network). This is what the Wide Area Network comprises.<\/p>\r\n\r\n\r\n\r\n

The utilization of old telephone lines <\/a>allows us to have the internet or the largest Wide Area Network of all networks. So, WAN works much like our home network, but it uses different protocols and covers a much wider area.<\/p>\r\n\r\n\r\n\r\n

Why Does WAN Connection Go Down?<\/h2>\r\n\r\n\r\n\r\n

There are several reasons we can experience WAN connection down<\/a> issues with our network. It\u2019s an unusual error, but it happens when something\u2019s wrong with the ports we\u2019re using on our router, the cables, the ISP\u2019s infrastructure, or the outlets in our home:<\/p>\r\n\r\n\r\n\r\n
