The Best WiFi Extender for Xfinity Internet Service
Do you have WiFi “dead zones” of your apartment or house? Suffering from data delays with slow-loading websites and buffering Netflix? After ensuring you’ve optimized your WiFi network, it’s time to get a WiFi extender, which, as its name suggests, extends the reach of your Xfinity WiFi network to all corners of your home.
Why is a mesh WiFi system the best extender for most Xfinity customers?
The most convenient and cost-effective WiFi extender for Xfinity customers is a mesh WiFi system, which uses signal amplifying/repeating nodes placed around your home to bounce the signal to all corners.
Simply put, mesh WiFi systems provide the best coverage with the easiest setup. The base unit of a mesh WiFi kit simply plugs into an Ethernet port on an Xfinity Gateway (or compatible third-party modem) and then assumes the signal-beaming duties of a router. The companion mesh network “nodes” (wireless signal receivers/re-transmitters) are plugged into power outlets, spaced out 20-30 feet from the router and then from each other, in a pattern that circles around the worst WiFi signal blocking barriers in your abode. Designed for self-installation in just 30 minutes, you are guided through the entire setup process using a companion app (for smartphone or tablet) that activates and monitors the component parts, and indicates (with a gauge or color coding) when you’ve ideally placed the nodes for optimal coverage.
How we picked the best mesh WiFi system for Xfinity
Not all mesh WiFi systems are created equal. When evaluating mesh WiFi systems, we took into consideration speed, signal strength, the ability to handle older products (which require a 2.4Ghz WiFi band), aesthetics, and ease of use.
From an aesthetics standpoint, some of the nodes are kinda clunky, trophy-sized obelisks (think a mini Washington Monument); others (like Xfinity’s own branded xFi Pods) are little roundish things that plug directly into a wall outlet (and resemble a night light, air freshener or rodent repellent). Most hide their antennas inside the packaging – a nod to aesthetics that arguably diminishes performance. Some nodes have an ethernet port for hardwiring to a piece of gear, like a gaming console or smart home device hub.
Speed & range
The latest WiFi technology is WiFi 6, or 802.11ax, with speeds of up to 6.6Gbps. (All WiFi speeds are cited at their top theoretical speed since real-life conditions vary the actual speed considerably.) However, the top tier of service for Xfinity customers is Gigabit Pro, which delivers up to 2Gbps. So, unless you’re just sending data between devices in your home, the 6.6Gbps products are overkill and cost two to three times other systems.
Mesh WiFi systems operate at two bands or different sets of frequencies. These dual-band systems have two networks, one running at 2.4Ghz and one at 5Ghz. For most people, a dual-band system provides plenty of throughput. Tri-band systems have one 2.4Ghz band and two 5Ghz bands, which makes it easier to manage congestion and optimize speeds. However, tri-band systems cost more than dual-band systems and aren’t worth the upgrade for most people.
When considering range, it’s important to note that all mesh WiFi systems and WiFi extenders suffer some signal drop off as you move further from the base. Like a new car that loses value the moment you drive it off the dealer’s lot, a mesh net starts decreasing the available signal strength as soon as you move a few feet from the Gateway and connected router. Then that signal continues to diminish in strength with each successive node you add to the chain. The best mesh WiFi systems lose little throughput even far away from the main base.
Handling old and new devices on the same network
Mesh WiFi systems mash-up the signals running on both 2.4 GHz and 5GHz radio bands, so the two bands are accessed with a single SSID (network name) and password. Intelligent “band steering” and “beamforming” technology then directs the traffic, so your gear connects to the most appropriate frequency and node. 2.4 GHz signals travel farther but more slowly; 5 GHz signals are shorter in range but run far faster – so are better for data-intensive applications like video gaming.
A complication can arise with creating a single network, though, when you have older products like security and baby cams, smart door locks and multi-room speaker systems that only work on 2.4 GHz. Sometimes, these older products can't "see" the new mesh WiFi network because the new network is trying to connect on the 5Ghz band. The best mesh WiFi systems can identify devices that require a 2.4Ghz and provide a temporary separation of the two bands so that devices that require a 2.4Ghz connection are identified and handled accordingly.
Our pick for the best Xfinity extender for most people: Xfinity Gen 2 xFi Pods
Comcast offers a mesh network solution that is custom-designed to work with Xfinity WiFi routers, called xFi Pods ($119). The xFi Pods being sold today on the Xfinity site are new second-generation xFi Pods that offer the best combination of speed, range, and ease of use for most Xfinity customers looking to extend their home WiFi network.
Gen 2 xFi Pods use the router built into the Xfinity Gateway and run with the same xFi app you’ve probably already installed on a smartphone or tablet to monitor bandwidth use, set parental restrictions, and check on your Xfinity Home security system. Because Xfi Pods are part of the xFi platform, they are easy to install, with the app directing and showing when you’ve made an ideal placement. And because they are small and cute and plug directly into a wall outlet, these xFi Pods virtually disappear.
The new Gen 2 xFi Pods have a tri-band AC3000 radio and a maximum throughput of 500 Mbps (versus 200 Mbps of the Gen xFi Pods). And, the Gen 2 xFi Pods have a third (5Ghz channel) radio devoted to back-channel communications and service optimization, in addition to a 2.4Ghz band and 5Ghz band. This puts the Gen 2 xFi Pods in the same class of mesh system as Amazon’s popular eero systems and Google’s Nest WiFi.
In our recent hands-on testing of the Gen 2 xFi Pods, we found little drop off in speed when separated from the Gateway by a wall and more than 30 feet away (the Gen 1 xFi Pods had roughly a six-times reduction in signal strength from the Gateway’s direct output in our tests). And when testing on another floor and approximately 25 feet from the Gateway, there was a mere 21 percent drop in speed.
From the Xfinity app, you can set parental controls for your children’s devices, including blocking explicit content, pausing the internet, and setting time limits. These parental controls are on par with other mesh systems.
When you install the Xfinity Gen 2 xFi Pods, one network is created with two bands instead of two networks with separate network IDs (SSIDs) and passwords. The Xfinity Gateway and xFi Pods automatically steer traffic to one of the two bands, 2.4Ghz or 5Ghz. For most people, this isn’t a problem. However, without two networks and manual control over which devices access each network, you can run into issues with old devices that can only run on the 2.4Ghz band not being able to “see” other devices because they are operating on the 5Ghz band. There are also some people who may want to manually allocate bandwidth to ensure maximum throughput for a gaming system or streaming device, for instance.
For most people, the new Gen 2 xFi Pods are the right choice for extending WiFi service throughout their home. They provide the maximum throughput, easy setup, robust parental controls, and Xfinity tech support to help with all of your internet issues.

Our pick for the best Xfinity extender for people with old 2.4Ghz devices: Google Nest WiFi
Robust performance, easy setup, and some unique extras make the Google Nest WiFi system the best WiFi extender for Xfinity customers that have old devices that just work on the 2.4Ghz band. The Nest WiFi system has an attractive design, so you’ll be happy to place the node, or Points as Google calls them, out in the open. And, with such a strong signal, you can get away with fewer nodes than other mesh systems and still have whole-home coverage.
No surprise given its Google lineage, the Nest WiFi system is praised for its cloud-based Artificial Intelligence, which helps the Nest WiFi system to “beam steer” WiFi signals in the most efficient manner to deliver WiFi throughout your house. Nest WiFi uses an active monitoring protocol to weigh the relative distance between a device needing WiFi and the Nest WiFi components, as well as the current WiFi needs for each connected device and the capacity of the available frequency bands (2.4 or 5 GHz). All of that is done to increase overall system efficiency and make the most robust and fastest possible connection at any given moment. CNET found the two-piece $299 combo offered enough signal strength and band steering to provide sufficient coverage at the 5,800-square-foot CNET Smart Home. The rig “aced” the mesh tests and was never guilty of “routing the connection through the extender when connecting directly to the router was faster” – a common complaint with less agile systems.
From the Google Home app, you can set parental controls for your children’s devices, including blocking explicit content, pausing the internet, and setting time limits. You can also prioritize devices, so you can ensure your living room TV will get flawless 4K streaming.
Beyond its WiFi capabilities, Nest WiFi distinguishes itself by building Google Assistant smart speakers into the Points. This opens up all sorts of voice-activated opportunities you won’t find built into other mesh systems, including the ability to prioritize specific devices, shut off WiFi to specific devices, block adult sites and create a guest network. And like conventional smart speakers, Points can recite a recipe and set a timer, share news, sports scores, and the weather, play music, make a hands-free phone call, control room lights, thermostats, and door locks. The discreet mushroom-shaped Points come in three colors – white, light blue, and a light peach – to blend into your décor more easily. (A privacy switch on the back of the Points mutes the microphone.)
Nest WiFi tops several “best of 2020” reviewers lists, including being rated “Best overall” and “most well rounded” mesh WiFi system of 2020 by CNET, earning an “Excellent” rating (4 out of 5 stars) by PCMag, and scoring 4.5 (out of 5 stars) by TechRadar. Consumers also love Nest WiFi, giving it 4.3 stars on Amazon and 4.5 stars on Best Buy.

The best Xfinity WiFi extender for heavy users: eero Pro
While mesh WiFi systems can handle up to 100 devices, most have trouble smartly juggling the data demands of four or five simultaneous heavy users. The eero Pro (2nd generation) mesh WiFi system not only manages heavy data loads with ease, but it also outperforms other systems in reach and speed at the far ends of the network, making it our pick for the best Xfinity extender for heavy users.
In lab testing by Wirecutter, they found that even with six devices pounding simultaneously at the system, the eero Pro base router and nodes, called Beacons, connected “seamlessly to devices all over” the lab. And despite signal hops through two Beacons, the measurable signal speed was still plentiful at the other end of the 80-foot long, multi-room facility – with speeds reduced by just one-third from that measured at the base station. Reviewers at Android Central also marvel at how “seamless” the handoff of service is when moving a smartphone or tablet from one eero node to another – a talent observable in the app.
How does all that happen? The eero Pro is a tri-band system with a separate, second 5GHz channel radio that is devoted to communicating the millisecond-by-millisecond needs for signal apportioning and steering.
Both professional reviewers at Consumer Reports and user reviewers (Amazon rating is 4.6, Best Buy is 4.8) also applaud the app-coached setup of the eero Pro and Beacon nodes as unusually easy and speedy – with each piece taking just ten minutes to add to the system. Once the network is set up, controlling the network functionality, including the scheduling of device access times for kids, pausing internet access, and checking device usage is also just a few taps away.
Like the Nest WiFi Points, the Beacons have a second function. Each Beacon has a built-in LED nightlight with an ambient light sensor and automatic dimmer, befitting its wall-hugging, night-light-like appearance.
Size: 4.76 (w) x 2.91 (d) x 1.18 (h) inches per Beacon
Speed: Tri-band, AC2200 MU-MIMO with backhaul
Range: 1,750 square feet per router, 1,500 per Beacon
Ethernet jacks: 2 on the router
Parental controls: Yes
Extras: Built-in LED nightlight with automatic dimming
Price: $399 for eero Pro router and two Beacons on eero, check price on Amazon
