Modem vs modem-router combo

One of the major factors that you will need to consider is whether you opt for a modem or a modem-router combo. A modem on its own will be arguably much cheaper than a modem-router combo. So you will still be saving on those rental fees that you can invest in other things. However, it’s worth bearing in mind that a modem is only part of the technology you need to get connected to the internet. You will still need a router to attach to your modem so that you can get those super fast speeds.

A modem-router is two devices built into one. So you’ll still be able to save on those modem rental fees, but you won’t have to fork out extra money on getting a suitable WiFi router to get connected to the internet. However, the downside to these models is that they are often much more expensive than the modem on their own. You should weigh up the pros and cons of both to help you decide which will be the best option for your needs.
