It also performs the reverse of this process. Now, you need a device that turns these signals into digital to make them readable by your digital devices. These signals are all analog and aren’t readable by computers and other smart devices. Your ISP transfers data signals via telephone lines, DSL, optic fiber, or satellite from its centers to your home. You require a router if you have several devices that need an internet connection.īefore wireless technology took over our lives, the internet was only accessible via a wired connection made possible by modems.Īs a result, the modem was the only device required for an internet connection. However, the modem can give internet to only one device via a cabled connection. To better clarify whether a router can work without a modem, we need to know the difference between these two devices.īoth are essential for establishing an internet connection but have different functions.Ī modem is a device that brings internet from your ISP centers to your home. You can use the router to create a local area network (LAN), connecting several devices and sharing files inside the network. However, the router doesn’t need the modem if you don’t want to access the internet.
The router distributes connections among devices, enabling them to connect to the internet wirelessly. On the other hand, a modem can work without a router because it can access the WAN and deliver internet to one device via an Ethernet cable. Without a modem, the router can’t access the world wide web or WAN to communicate with the outside world. Yes, a router can’t work without a modem if you want to connect to the internet because a modem provides internet to the router.Ī modem works like a translator that changes analog signals to digital and makes them readable by computers and smart devices. More importantly, can one work without the other?įor example, if you have a router, do you need a modem to use it, or can it be used alone?ĭoes A Router Have To Be Connected To A Modem? If you’ve never bought a modem and router, you may not know how they work and fit into a home internet network.įor example, can these two devices replace each other? Now we use the term “modem” to mean any device that receives the raw signal from an Internet service provider and puts out a signal the computer and other devices can use.Routers and modems are critical components of any internet network to give you access to the world wide web. Some examples of modems include – Cable Modem, ADSL Modem, HDSL Modem etc.A modem (modulator/demodulator) was originally a device that took the analog signal of the phone line and converted it into a digital signal that a computer can understand. The functionality of modems is to modulate and then demodulate the signal and so that they are received at the each side of the connection. Modems generally work in pairs, with one modem at provider end and other at customer premises end. The dynamic or static public IP address which the modem obtains from ISP is passed on to your PC.
CABKE MODEM VS ROUTER PC
The modem acts as a “bridge” between customer PC and your ISP.
Ī Modem is a device that transmits and receives data over the plain old telephone system’s (POTS) analogue lines. The computers can connect to printers and other devices on the network and infact share each other data. For instance, in a home network, various desktop computers, laptops, printers and scanners may be connected through an Ethernet cable to the router. It will have several Ethernet ports to which one device per port is attached. A router can also select the best route for packets to take in large interconnected networks. A router rejects packets unless they match defined attributes (eg specific source or destination network addresses). A router learns more about the networks to which it is connected and can be more selective about the packets it passes on. It forwards packets based on network addresses (Internet Protocol addresses) between ISP’s router and LAN. A Router is a device which acts as an interface between two networks ie LAN and WAN.
