If you want to buy your own device, you have to take into account some important things to purchase a model that suits your needs most.

Speed

Each Internet plan offers super-fast performance. When you subscribe to Xfinity, check the speed offered by your subscription plan before buying a modem. If it’s not powerful enough, you won’t get the speed you pay for.

Channel Bonding

Imagine that modem channels are lanes on a freeway. More channels allow more data to be transferred per second. Due to this, you can get faster Internet. However, more channels will be more expensive, so if you want to save some money, choose a model with channels that are suitable for the speed that your plan offers.

Wireless Standard

When choosing the best modem for Xfinity, you’ll notice various numbers and letters that start with “802.11.” Three common standards can be found in modern models:

11ac is the most common for modern models. It’s also called Wi-Fi 5, 802.11ac and it provides speeds of up to 1.3 Gbps.

11n (Wi-Fi 4) was used for the previous generation. It supported speeds of up to 450 Mbps and is still present in some inexpensive devices.

11ad and 11ax (Wi-Fi 6) are the latest standards supported by some high-performance routers. They offer up to 4.8 Gbps (4 times faster than 802.11ac), but not many devices and Internet connections allow you to make the most out of this protocol.

Choose a model that supports 802.11ac or Wi-Fi 5 to use modern connection speeds.

Ethernet Ports

For modems, the number of Ethernet ports is very important. 4 ports let you connect more devices simultaneously. If you have just 1, all you can do is to purchase a router and connect your modem to it.

Security

This is another significant aspect, you need to pay attention to when looking for the best modem for Xfinity. It should protect your data from being accessed by hackers. Remember to set at least a WPA2 or WPA3 encrypted password.
