How to Choose the Best Fiber Optic Modem?

Your Router Should Have a Smartphone App

Until recently, it was impossible to configure wireless router settings without using a complicated UI accessed via a browser. Since many users found it too difficult to adjust settings in this way, manufacturers released handy mobile apps that allow people to configure various parameters in no time. If you aren’t ready to spend hours trying to figure out how to configure your router, check if a model of your choice has a smartphone app. It will allow you to adjust the settings on the go and manage access rights regardless of your location.

When making your choice, keep in mind that there are different apps available that vary in their usability and sets of features. For instance, some routers have mobile apps that allow you to set the Wi-Fi password and configure other basic parameters. If you want to control other settings, it’s better to select a model with a more advanced app.

Upload and Download Speeds

When looking for a modem, you will notice that manufacturers indicate its upload and download speeds in the description. While some users tend to disregard this information, make sure to read the description to find it. For instance, you might see that a modem has speeds of up to 600 Mbps without any indication whether it’s an upload or download speed. In this way, manufacturers always indicate download speeds. If a model has an estimated download speed of 1 Gigabit, it indicates that you will be able to download files at up to 1,000 Mbps. An upload speed is usually lower. It’s about one-quarter the download speed.

While advanced fiber modems allow you to download large amounts of data more quickly, you need to understand that the speed also depends on your subscription plan. If your modem supports a download speed of 1.4 Gigabits, but you are paying for a subscription plan that allows you to download data at 25 Mbps, the overall speed can’t be higher than the limit set by your ISP. However, if you want to purchase a future-proof model, it’s better to buy a more expensive modem to avoid upgrades if you decide to switch to another subscription plan.

What about Security?

While many routers allow you to configure their privacy settings to your liking, you won’t need to think about security issues when choosing a modem. However, sometimes you will still need to make some adjustments to ensure that your data is safe. For instance, many modems are fitted with Broadcom chips. They have a dangerous vulnerability that allows hackers to control your modem and use it to access suspicious websites. While Broadcom claims that they have fixed this issue, you still need to contact your ISP to check if your modem has it or not. Internet Service Providers usually upgrade the firmware if any issue arises, but these updates are often late. For better protection, you can also purchase antivirus software, however, there is no guarantee that it will block all online threats.


  • • Does a type of modem matter?

Yes, since different models vary in upload and download speeds. While basic fiber modems support low speeds, more expensive models allow for a high-speed connection.

  • • How do I know what model I use?

You can find this information on your modem. Usually, manufacturers indicate a number of a model and a download speed. If you can’t see the name of a manufacturer or a model number on your modem, you can find this information by using an FCC number.

  • • Should I buy a modem and router separately?

It’s better to purchase both a modem and a router since it allows you to configure the network settings to get faster speeds. Besides, you can quickly replace your router if it gets outdated. If you are on a budget, you can buy a 2-in-1 model, but a separate router will have more advanced features.

  • • Is it necessary to have both a modem and a router?

Routers are convenient when you need to connect your devices, such as computers, Smart TVs or printers, to the modem. They can be used without a modem as well. For instance, you can create a LAN without accessing the Internet. In this way, your devices will be connected.
