A few pieces of network equipment are necessary to bring the internet inside your home or workplace. The modem is the most important piece of equipment. The modem acts like a gateway between your network’s internet connection and the rest of it. Three modems are the most commonly used today for each type of internet connection. DSL, fibre-optic and cable are the most common types of modems. The modem you’ll need is determined by your ISP (Internet Service Provider) and the infrastructure available.
You’ll probably want to use the internet signal on more than one device after you get it into the space where you wish to connect to the network of all networks. You’ll now need to purchase a router, connect it to your modem, and configure it to meet your needs.
What is a router in a network?
A network router is a device that transmits data packets between networks.
Is it difficult to understand?
Let’s explain using a post office analogy.
Each device in your network (e.g., a tablet, a notebook, a computer, etc.) is like a house or business in your town, city, or village. Every device on your network has an address. It sends and receives data every time you connect to the internet via one of these devices. These data are sent in small data packets, similar to letters. Each one has a specific address to which they must be delivered. The router is a post office. All packages that arrive at the router are forwarded to the next router (postoffice) if they are leaving a network or delivered to the device in your network. It is the equivalent of not having a postal office. There is no one to help you redirect your mail and get it to where you need it.
Now let’s see how you can access the settings and configure the router.
This can be done in three ways:
- Direct or local access
- Remote command line access
- Remote use of web GUI
Direct or local access to the router
You’ll need physical access to the router and a special cable called a rollover cable to make modifications to the router this manner, as the name implies. The console port on the router receives one end of the cable, while the other ends are connected to your computer. Remote access to router configuration is not permitted. This is your only option if you require additional security. If you choose this option, you’ll need to download and install a terminal emulator programme like PuTTy, HyperTerminal, TeraTerm, or something similar. You can edit the router’s configuration file with these tools. These programmes are usually free to download and may be found by conducting a simple Google search. You will, however, need to setup them in order for them to detect and display router settings in their window.
This is the safest option, but only use it if you’re certain you know what you’re doing.
Remote command line access
This is where you can connect to the router over the network. Two methods are available for connecting to the router, Telnet and SSH. They provide the same functionality as direct access, but you don’t have to plug your PC into the router. This means that you can access the router from any location in the world, and use command lines to make adjustments. This must be enabled in router settings. The preferred method to connect is via SSH, which is encrypted. This is another method you should trust professionals with if you don’t have the right knowledge.
Remote use of web GUI
We now have the easiest way to set up your router. This is done via the web browser and the graphic user interface. It’s simple and most settings are explained in the admin panel.
What is a network switch?
A network switch allows you to quickly connect multiple devices via cable. There are two main types: managed and unmanaged switches.
Unmanaged switches are a plug-and-play device that is ready to use right out of the box. You only need to plug in the Ethernet cables to connect your devices. It will work.
Only one thing. Make sure you read the specifications and purchase the appropriate Ethernet cables if you want the fastest possible speeds from your switch. If your switch can handle speeds up to 1Gb/s, you should buy an Ethernet cable labeled cat5e or cat6 for faster rates and better reliability.
This type of switch doesn’t come preset, and its settings can be adjusted to your needs using the same methods you use to set up the router. They are best suited for businesses and large networks that require fast access to all devices and fine tuning. You don’t need to be tech-savvy if you do not know how to use them.
How to set up the router
There are three types: static IP, PPPoE and dynamic IP.
Regardless of the type, to set up the router, you’ll need to go to the Admin panel or enter the changes manually. A web browser is recommended, as well as a GUI (Graphic User Interface).
Access the admin panel by using a web browser and a computer that is connected to the same network. The router’s IP address, as well as the administrator’s username and password, are required. These details can be found on the label on the back of your router. In the browser address bar, type the IP address. This will take you to the login page, where you must enter your username and password.
Look for the internet or WAN settings, as well as the “internet connection type,” once you’ve entered the admin panel. Choose the one you have (if you’re not sure, ask your ISP).
If your provider employs Static IP, you’ll be given a page of information to type into the router’s admin panel. There will be a WAP IP address and subnet mask provided. Also provided will be the gateway IP address and DNS server address.
Save the settings and type them in.
If the service is PPPoE your ISP will give you a username/password. In certain cases, you may also be given a service number. These can be entered and saved.
Dynamic IP is the third and most popular option. If you are unsure, then choose dynamic IP. The ISP will handle the rest. Enjoy the settings.
How do you set it up?
Unmanaged switches are used in most home and small office applications, as previously stated. Plug-and-play gadgets in small packages. The Ethernet wire must only be connected to the router’s port. Separate cables and ports can be used to connect other devices to the switch. This concludes the discussion.
