Xfinity provides the xFi gateway if you opt for equipment rental. They charge around $14/month as a rental. I surveyed 190 Xfinity gigabit users and found that around 63.8% of them use the xFi XB6 aka Arris TG3482G. In case you’ve upgraded to the Gigabit speed or are a new customer and want to know if the xFi XB6 would work for your requirements then this review shall be helpful.
In this review, I’ll be talking about the XB6 gateway, my likes & dislikes, speeds & throughput, wireless & voice connectivity, design, hardware, and overall performance. Everything written here is a personal experience. However, please contact me via comments if I’ve missed any detail you’d be interested in knowing.

Xfinity xFi XB6 Review
Xfinity xFi XB6 is an easy-to-setup wireless voice gateway. It’s highly suitable for people who care less about the technical setups and don’t want more control. However, in my experience, it has a coverage area of 1,200 sq ft and the capacity to handle over 30 devices. However, if you live in a large house then get the xFi Pods which costs around $199 for 2 pods.
Overall, I believe that the rental ends up costing $144/year and these last for 4-5 years, so you’ll end up paying around $600-720 over a period of time. However, you could get an Xfinity compatible modem (even the high-end devices like Arris S33 or the Arris SB8200) shall cost around $150-180 and a router could cost anywhere between $100-$200. So eventually, it’d cost around $300 for 5 years.
In the case of large homes, the cost shall go around $920 ($720 for rental + $199 for xFi Pods) on the other hand if you don’t rent, you can get the Arris SB8200 for around $150, and a reliable mesh system for Xfinity which could cost between $150-$350 depending on the features. If I calculate the maximum costs involved, it’d still be $500 ($150 for the modem, $350 for the mesh system) with much more power and control!
What I Like and Dislike
- Gigabit wired and wireless internet
- Easy to set up & manage
- Straightforward design
- App offers numerous control features
- Updates from Xfinity
- Features Intel Puma 7 (bad chipset)
- Single heat dissipation vent
- Limited coverage area
xFi XB6 Speeds & Throughput
Arris TG3482G Xfinity wireless gateway features DOCSIS 3.1 and Wi-Fi 6 standards. DOCSIS 3.1 is the latest technology used in cable modems that supports speeds up to 2.5 Gbps. And integrated with dual-band WiFi, you can expect good download and upload speeds by connecting wirelessly.
The built-in WiFi 6 router comes with seven additional 160MHz channels, which is supposed to improve bandwidth distribution.
However, it performs quite average, especially in terms of latency due to the inferior Intel Puma 7 chipset. Hence, I can’t recommend XB6 gateway for data-intensive tasks such as gaming and live streaming.
So, Kurt, does the Xfinity XB6 xFi advanced gateway modem work fine for browsing? Well, yes. I tested it thoroughly by browsing on multiple devices to understand if it was worth it.
And if you ask me about the Arris TG3482G speed, I tested it with Xfinity’s gigabit plan and received download and upload speeds up to 750 Mbps and 300 Mbps, respectively. But again, it’s a speed test result and may vary based on your internet plan, location, placement, and more.
ISP Compatibility & Service Plan Suitability
Arris TG3482G is an Xfinity-exclusive device, so it won’t work with any other ISP. However, the Xfinity XB6 modem is backward compatible with DOCSIS 3.0 technology so it will work with most internet plans from Comcast Xfinity. However, I won’t suggest investing in this device if you plan to use it with internet packages of less than 500 Mbps.
Design & Connectivity
XB6 modem by Xfinity boasts a straightforward design with an exterior matt black finish and a sturdy case. The device comes with dimension tags of 6.69 x 9.06 x 6.69 inches and weighs 3.25 pounds, making it a tad heavy. Nevertheless, its vertical orientation and flat bottom let you keep it anywhere without wobbling.
Further, it comes with a single blue light, which promises a plain view of the surroundings without any distractions and hindrances. (Learn more about Arris modem lights)
Being an xFi advanced gateway, it demands a coaxial cable connection, and there’s a port for that at the rear. There you’ll also find four Ethernet Ports (single 2.5Gbps, three 1Gbps) and two phone jacks to use Comcast’s voice services.
And if you’re wondering if there are any alternative voice-capable modems that work with Xfinity, then check out my list of recommended modems with phone jack.
What I didn’t like about its design is that it comes with a single vent at the top, which might not be enough to dissipate its heat. Using it for longer overheats the device and crashes the speeds across several devices, which was a potential issue. I tried using it with an exhaust fan on the top, but it didn’t work much.
Hardware & Performance
That said, you gain advantages in networking and computing performance, packet processor flexibility, RF noise rejection, and engineered for various LAN and WAN use cases.
The processor works with 673 MB of RAM. And a decent amount of NAND memory. It stores necessary network-related information, which is passed on to the processor when running and speeds up the data transmission process. Thereby, the existing network congestion is eliminated, and you can now enjoy a lag-free internet user experience.
Xfinity xFi XB6 Setup
Setting up networking devices can be difficult, especially if you have no idea how these devices work or are unfamiliar with modern technology like my grandpa. Well, it’s about to change with this Xfinity xFi gateway setup.
I’m saying this because once you’ve installed the free Xfinity xFi app on your device, you just have to tap through following the displayed instructions, and you are ready to go. This app offers a higher degree of control over setup and maintenance, where you can create various profiles, block WiFi, set parental controls, and many others.
Besides, you can also limit devices and internet consumption.
Frequently Asked Questions
xFi gateways of Xfinity gateways are all-in-one devices that come with several features like voice and internet connectivity, network security, WiFi coverage, speed, and control for an ultimate experience.
I tested the xFi XB6 aka Arris TG3482G at my workspace, and it got the job done in delivering internet throughout the 900 Sq Ft area. However, you might need to reboot the device monthly to ensure uninterrupted delivery.
To install the XB6 modem, start with connecting one end of the coaxial cable to a socket, and another to the input of the gateway. Then, take the power club to connect it to plug one end into the device and the other into the outlet. Your gateway should automatically turn on, and if not, press the power button and watch for the connection light to turn on.
xFi complete is basically an upgrade of xFi and comes with some advanced features. So, the difference between xFi and xFi complete is the latter comes with features like whole home WiFi that evaluates your network performance to deliver most network coverage throughout your home.
xFi gateway is secured in terms of keeping unknown networks and devices away from connecting to it. However, Norton is an antivirus with advanced security to prevent attacks from third-party sources, ransomware, and other potential network threats. So, you need to run antivirus on your device despite having xFi security.
If you’re an existing Xfinity user or planning to be one, Arris TG3482G Xfinity wireless gateway is a good choice unless you indulge in latency-related activities. With 32 x 8 bonding channels, DOCSIS 3.1, and Wi-Fi 6 support, it’s one of the most promising wireless gateways I tested so far. I had no problem recommending this device if it didn’t feature the Intel Puma chip.
Intel Puma chip makes it a bad choice, so I would suggest getting a reliable router for Xfinity.
