Review of Best Xfinity Compatible Modems
Xfinity recently raised the price of their rental from $10 to $11 – and there is no indication that it won’t happen again. This fee may seem small but will quickly add up to carve a dent in your pocket. When you rent a modem, you are not sure of what Xfinity will deliver to your doorstep until it arrives. However, when you buy your own modem you have the luxury of choosing exactly what you want. That said, here is our list.
Motorola MG7550 – Best overall
Arguably the best modem for Xfinity is Motorola MG7550. This modem ticks the boxes in the areas that matter the most starting from the design. The tower design allows it to take up less space as well as gives room for the integration of more ventilation. Note that good ventilation improves the life of a modem. This modem has 16 upload and 4 download channels which is pretty impressive. It comes with 4 Gigabit Ethernet ports which extend the number of connected devices you can use at a time.
best modem for Xfinity, Period!
One of the major problems among modems with router is poor range. Motorola MG7550 has impressive range, thanks to the AC1900 dual band Wi-Fi router. In addition to that, it has wireless Power Boost technology which amplifies the wireless signal’s speed and range up to the legal limit. MG7550 works on Wi-Fi DFS frequencies thereby lowering the chance of interference for neighboring devices. The main benefit of a modem router combo is that it eliminated clutter from wiring and conserves space.
The icing on this product is a 2-year warranty, Broadcom cable modem chipset that provides security from Denial of Service attack (DoS), as well as lightning and power surge circuits. You can have a decent rest knowing that it will outlive the cost. Talking about cost, Motorola MG7550 can be considered expensive. Also, it lacks USB port meaning you can’t share files from hard drives. However, the pros far outweigh the cons.
- Combines Gigabit modem and AC1900 dual band Wi-Fi router
- Integrates DFS and wireless Power Boost technology
- Broadcom chipset prevents DoS attack
- Circuit has lightning and power surge protection
- Comes with 2-year warranty
- Slightly pricey

You will get 1 Gigabit Ethernet port which you can connect directly to your device or to a wireless router. Thankfully, it works with any router.

Buying Guide for the Best Modems for Xfinity
Besides the ten modems on our list, there are over fifty more approved modems by Xfinity. Perhaps you don’t like any of the modems on our list or you simply want to do your own research, there are a few factors you need to bear in mind when doing so. This buying guide was designed to help you to make the best decision in this regard.
Buying a modem that has not been approved by Xfinity will set you on a path of multiple problems. Since the modem has not been approved by the provider, you may not be able to activate it. It is best you scroll through Xfinity’s website and check to see if the modem has been approved.
Xfinity has seven package plans and each of these plans have their speed cap. When buying a modem, it is always important to make sure that they fit into your subscription package. For example, using a modem that is suitable for Performance Pro+ on Blast! will only lead to a limitation of speed. Likewise, the fastest modem will not increase the speed of your Internet if you are on Performance Starter+ package.
Modem Router Combo
A modem router combo eliminates clutter of wires as well as frees up space on your shelve. However, they are more difficult to upgrade. On the other hand, a standalone modem is a lot easier to upgrade. The choice is ultimately up to you.
When buying a modem router combo, it is crucial to pay attention to the wireless range. Preferably, you should go for a router with the 802.11ac technology or the advance Wi-Fi 6 with 802.11ax technology. These Wi-Fi technologies have better coverage than the previous versions. Also, keep your eyes peeled for beamforming and power boost technologies which enhance the Wi-Fi range as well as give you the luxury of focusing your network on a particular device.
For standalone modems, the number of Ethernet ports is vital. Modems with 4 Ethernet ports allows you to connect more devices at the same time. When you have 1 Ethernet port, the best you can do is to get a router and connect your modem to the router.
Modems with some form of security is always better than those without special securities. The emphasis on security should not be about protection from hackers alone. Security in this case should consider the interference from neighboring Wi-Fi.
Thankfully, there is a large number of Xfinity compatible modems. Therefore, irrespective of your subscription package you will certainly find the right modem for you at a reasonable price. Ideally, pay more attention to other features and less on the price.
