Routers

Router Connections

A router boasts multiple connection options, either through physical RJ45 ports or wireless methods, such as Wi-Fi. However, not all routers feature the same types of connections. It all depends on the type of router you have. The following list is some options you may find on a router:

• Ethernet Ethernet is the most common form of physical network connectivity. This utilises the RJ45 port and is connected via an ethernet cable. Ethernet offers high-speed reliable transmission with minimal susceptibility to interference from outside sources.
• Wi-Fi Wi-Fi is a wireless network technology, which allows the router to communicate with other devices without a physical connection. Instead, Wi-Fi utilises radio signals, generally using the 2.4GHz and 5GHz ranges. However, Wi-Fi signals are susceptible to interference, either from crosstalk between devices or physical impediments, such as thick walls or distance. Modern routers overcome these issues, by featuring the latest Wi-Fi technologies, which add additional radio wavelengths and boost the power of existing signals.
• DSL DSL is the most common way a router connects to the internet. DSL modems utilise phone lines to transmit and receive data.
• Cable Cable is another method of connecting to the internet. Unlike DSL models, cable routers utilise specialised coaxial cables to access the internet. As these are designed for internet access only, they provide a notably faster connection than DSL. However, a cable connection requires additional hardware, meaning they are commonly only seen in highly developed areas, such as cities or large towns.
• Fibre Fibre optic connectivity is an advanced type of cable connectivity. Instead of using electrical transmission along copper cables, fibre optics transmit data through light signals via optical fibres. This is an extremely fast transmission method, offering magnitudes faster connection speeds compared to traditional DSL. However, it requires specialised equipment, meaning access is limited, even in urban areas.
