Establishing a connection between a router and a modem involves physically linking these two devices to facilitate internet access for multiple devices within a network. This process typically utilizes Ethernet cables to create a wired connection, enabling data transmission between the modem, which receives the internet signal from the service provider, and the router, which distributes this signal to connected devices.
The proper connection of these devices is essential for creating a functional home or office network. It allows multiple devices, such as computers, smartphones, and smart home appliances, to simultaneously access the internet. Furthermore, a router provides added security features, such as firewalls and password protection, safeguarding the network from unauthorized access. Historically, direct modem connections were common for single devices, but the proliferation of internet-enabled devices necessitates a router for efficient network management.
