Networking and Connection

How do computers talk between one another?

With the advancement of information and technology it is important to have a basic understanding of how your computer communicates through a network and over the internet.

Generally speaking, a packet is the most basic unit that is sent from one point to another containing data, just like an envelope. Each packet is made up of information including its destination, it’s source and timestamps but primarily the data in which it contains known as the payload or body.

How are the packets sent?

An ‘IP’ (Internet Protocol) is an address in which computers use to communicate with other computers on a network.

Packets are sent through your network connection using a specific IP address to reach their destination. Your router assigns each device on your local area network an IP address. When connecting to the internet, your internet service provider provides your routers interface with a wide area network IP.

What is a LAN and WAN connection?

A LAN connection (Local Area Network) is your private network, generally in a home or workplace. Whereas, a WAN (Wide Area Network) refers to your public connection to the internet through your internet service provider.

Connecting to your network

There are two ways to connect your device or devices to your network. Using an Ethernet cable linking your modem/router to your device’s network card is undoubtedly the most efficient method for achieving the highest possible connection speeds.

Alternatively, connecting through Wi-Fi eliminates the inconvenience of undesirable cables running through your house or workplace. Wireless connections can practically attain close speeds to a cable connection but certain factors are involved.

Is your Wi-Fi connection achieving optimal speeds?

Router placement is paramount to receive your strongest possible signal. Ensuring that your router isn’t in a cluttered environment will reduce signal restriction. Keep your router toward the centre of your home or workplace away from electronics and heavy duty appliances as they disrupt signal strength.

If you have a dual-band router, you have the option to change the frequency of your signal. Switching to the 5GHz band may be beneficial as it offers fast speeds than the commonly used 2.4GHz. Although the 5GHz band doesn’t handle distance quite as well it is likely to encounter less interference as the frequency isn’t as commonly used. We recommend using the 5GHz band for faster speeds if your router is within sufficient range.

There are alternative methods to boost your Wi-Fi signal such as Wi-Fi extenders and router upgrades. Mobile PC Pro can help you diagnose and install such products to get your network connection up to optimal speeds.
