To Buy or To Rent: Modem vs Router

Table of Contents

When it comes to setting up an internet connection at home, there are two main devices that are essential for a smooth and seamless internet experience – the router and the modem.

These two terms are often used interchangeably, but in reality, they serve different purposes.

So, when it comes to purchasing these devices, the question arises – should you buy or rent them? Let’s break down the differences and find out the best option for you.

What is a Modem?

A modem, or modulator-demodulator, is a hardware device that connects your home network to the internet service provider (ISP).

It is responsible for converting the analog signal from the ISP into digital data that your devices can understand and vice versa. In simpler terms, it is the gateway that allows you to access the internet.

What is a Router?

A router is a device that connects multiple devices to a single internet connection.

It acts as a central hub for your home network, allowing different devices to communicate with each other and access the internet.

Now, coming to the question of whether it is important to have a router if you already have a modem.

Its largely depends on your internet usage and the size of your home. If you live in a small apartment and only use the internet for basic tasks like browsing the web and checking emails, then a modem may suffice.

However, if you have a larger home or multiple devices that require internet access, then a router is a must-have.

Pros and Cons of buying router and modem


Cost savings

The most obvious benefit of buying a router and modem is the cost savings. Renting these devices from your internet service provider can add up over time, and buying your own can save you money in the long run.

Flexibility and customization

When you own your router and modem, you have the flexibility to choose the models and brands that best suit your needs. This allows you to customize your network according to your specific requirements, such as faster internet speeds or better coverage.

Better performance

In some cases, purchasing your own router and modem can result in better performance. This is because rental devices are often older models with limited features, while newer models on the market offer improved speeds and advanced features like dual-band or tri-band technology.

No monthly fees

When you buy a router and modem, you are not tied to any monthly fees or contracts. This gives you more control over your internet expenses and the freedom to switch internet service providers without any additional costs.

One-time investment

Buying a router and modem is a one-time investment. You don't have to worry about upgrading or returning rental devices when you switch to a different internet service provider. This can save you time and hassle in the long run.


Upfront cost

The biggest drawback of buying a router and modem is the upfront cost. While it may save you money in the long run, the initial investment can be significant. This may not be feasible for everyone, especially if you are on a tight budget.

Technical knowledge required

Setting up and managing your own router and modem may require some technical knowledge. This can be a challenge for those who are not familiar with networking concepts. However, there are many online tutorials and resources available to help you with the setup process.

Maintenance and upgrades

When you own a router and modem, you are responsible for its maintenance and upgrading. This means troubleshooting any issues that may arise and keeping up with the latest updates and security patches. This can be time-consuming and may require some technical expertise.

Compatibility issues

Not all routers and modems are compatible with every internet service provider. This means you may have to do some research or consult with your provider before making a purchase to ensure compatibility. In some cases, you may also need additional equipment, such as a separate modem and router, to set up your network.

No technical support

When you rent a router and modem from your internet service provider, you have the option to call their technical support for any issues. However, when you own your devices, you are solely responsible for troubleshooting and fixing any problems that may arise.

Pros and Cons of Renting router and modem

Renting a modem and router from your ISP is a popular option for many. Let's look at the pros and cons.


Lower upfront cost

Renting a modem and router means you don't have to pay a significant upfront cost, making it a more affordable option.

Technical support

Most ISPs offer technical support for the modems and routers they rent out. If you encounter any issues, they will take care of it for you.

Easy upgrades

If you want to upgrade your internet speed, you can easily do so by upgrading your rented modem and router.


Monthly fees

Renting a modem and router means paying a monthly fee, which can add up over time.

No customization

When you rent a modem and router, you have limited control and customization options. You have to use the devices provided by your ISP.

Long-term costs

Although renting may seem like a more affordable option in the short-term, it can end up costing you more in the long run.


In conclusion, whether you should buy or rent a router and modem depends on your specific needs and preferences. Buying a modem and router can save you money in the long run and give you better control and customization over your home network. However, it also requires an initial investment and can be technically challenging.

On the other hand, renting a modem and router is a hassle-free option and does not require any technical knowledge. But, it can be a pricier option in the long run. Ultimately, weigh the pros and cons and choose the option that works best for you and your budget.


Q1. What is the difference between a router and a modem?

A router is a networking device that connects multiple devices to a single network and directs traffic between them, while a modem is a device that connects your home or business to the internet.

Q2. should I buy or rent a modem?

It depends on your individual needs and preferences. Here are some factors to consider:

1. Cost: Buying a modem upfront may be a larger initial investment, but in the long run it can save you money compared to monthly rental fees.

2. Flexibility: If you like to upgrade your equipment frequently or switch internet providers, renting a modem may be a better option since you can easily swap it out for a different one.

3. Reliability: Generally, owning your own modem means you have more control over its maintenance and can ensure it is functioning properly. Renting a modem may mean relying on the provider for repairs or replacements.

4. Compatibility: Make sure the modem you purchase is compatible with your internet provider. If not, you may have to rent one from them anyway.

Q3. Can router work without modem?

No, a router cannot work without a modem. A modem is needed to connect to the internet service provider and establish a connection to the internet. The router then takes that connection and distributes it to multiple devices within a home or office network. Without a modem, the router would not have an internet connection to distribute.
