Best Modems of 2025

"I recently upgraded to the NETGEAR Nighthawk CM3000 DOCSIS 3.1 cable modem, and it has been exceptional for my high-speed internet needs. The modem supports top-tier speeds and works with all major cable providers. Plus, its DOCSIS 3.1 technology is perfect for heavy users like me. I love its compact design, which fits nicely with my other equipment."

"I bought this modem in November 2022 for my COX Giga Blast plan. The initial setup was smooth, but I recently experienced fluctuating download speeds. After contacting Netgear, I was disappointed to find out that technical support is unavailable for products over 90 days old. It felt frustrating to be redirected and then pitched a Pro-Protection plan instead of receiving help."

"On day one of using the modem, I found the setup with the Xfinity app to be incredibly easy, taking only about 15 minutes. I noticed an immediate improvement over my previous 8-year-old modem. This modem seems like a great addition to my system, especially with a new Netgear router on the way!"

"I found the installation ridiculously easy, needing zero help from Comcast. With just my phone and the Xfinity app, I had everything set up in about 5 minutes. This Hitron Coda56 modem gives me identical speeds to the X-Fi gateway. Just remember, it doesn’t have telephony jacks or Wi-Fi, so have a router ready if you need one. I'm really impressed and will be returning the gateway to save some cash!"

"My previous modem was fried from electrical surges, and I replaced it with this one. The performance is a million times better, taking my download speeds from 200 to 800 Mbps. I’m not sure what was wrong with the old modem, but this one is fantastic! Plus, it’s cheaper than renting from Comcast."

"I switched to this modem after struggling with a Netgear cax80 that dropped signals frequently. Since I made the change, I've had no issues at all. Unlike some Netgear models, this one supports high-speed upload rates, and for a fraction of the cost at around a third of the price of comparable Netgear modems, it’s a 10/10 in my book!"

"I purchased the ARRIS SBG8300 gateway to switch to Sparklight cable internet service. It was straightforward to configure, but I had to contact Sparklight support for a firmware update. Once updated, it performed excellently, delivering 110 Mbps download and 20 Mbps upload speeds. I did notice that the firewall was set to weak by default, but I switched it to medium for better security. Overall, I'm quite pleased with its performance after about a week."

"I upgraded my modem to the ARRIS Surfboard S34 to handle faster speeds with Comcast Xfinity. Setup was a breeze, and I was online in minutes. It supports multi-gig speeds up to 2.5 Gbps, ensuring I'm ready for future upgrades. Streaming and gaming are smooth, with no buffering or lag. The only thing to note is that it doesn’t come with a built-in router, but that’s typical for high-performance modems."

"My experience with the ARRIS modem has been great! It was very straightforward to set up and has provided fast speeds with Spectrum. I haven't encountered any issues, and it feels reliable so far."

"I found the setup to be incredibly simple and it worked perfectly with my ISP. In just five minutes, I had it running throughout my house."

"After replacing a Spectrum modem with the Netgear Nighthawk, my son has been able to game without interruptions. This modem has been vital for our consistent connection and speed while I work from home. I highly recommend it!"

"As an Xfinity customer, transitioning to my own modem was straightforward thanks to the Netgear app. The setup was smooth and self-explanatory, and the performance has been impressive. It fits perfectly in my switchboard."

"I’ve been using the ARRIS SB6190 modem with my 500 Mbps Xfinity WiFi, and I’m really impressed. The speed is excellent, and I’ve tested both upload and download rates without any problems. The installation was straightforward, making my internet experience smooth and reliable."

"I wanted to use my older Netgear Nighthawk D7000 as my primary router, and it took some effort to get everything set up. After contacting both Netgear and Arris, I finally found the right steps. Despite the setup challenges, the modem delivers full speed, and I’m satisfied with its performance."

"I purchased a refurbished unit and was concerned about the setup process. While I did face some issues with the app, once I got it registered, the modem worked perfectly. Fast internet has been a relief, but the app experience was frustrating."

"I was thrilled to find a renewed unit at less than half the retail price. Using the Xfinity phone app, I activated it easily, and my internet speed hit 800mb/s without any issues. After a couple of hours, however, I faced some internet struggles, which led to me reconnecting my original Xfinity Gateway. I suspect it might be a signal strength issue, but I'm planning to give the Netgear modem another try soon."

"I bought this modem to stop wasting $16 a month on renting a modem that I only used as a glorified cable modem. The activation was seamless, and I was online in minutes. The telephone activation did require a call to Comcast, but that was a minor inconvenience. Just a heads up, only one Ethernet port is functional unless you pay for more IP addresses."

"I purchased this refurbished modem and had a 90-day warranty. Initially, it worked well, but after three months, I encountered connection problems. Despite calling Netgear for support, I was told my warranty had expired, and I ended up buying a new modem from another brand. Just a word of caution if you're considering refurbished products."

“This modem is a solid workhorse. It connects effortlessly, and since I got it a month ago, it hasn't failed me. I called my ISP, provided the MAC address, and it was ready to go. I love not having to rent a modem anymore.”

“I appreciate having a separate modem from my router. It gives me the flexibility to upgrade either component without hassle. This has really improved my network reliability compared to the ISP's rental unit.”

“The speed is impressive. I was frustrated with my ISP's modem dropping the connection, but this modem has been blazing fast and stable. I feel much happier and secure with it.”

"I found this router/modem combo to be easy to setup and simple to use. It has all the features I wanted, and the customer support is great. I was pleasantly surprised that my 'renewed' item arrived in pristine condition with a 90-day warranty from the manufacturer."

"After renting a modem/router for years, I decided to switch to the Netgear modem/router. While the setup wasn't completely straightforward, the activation was easy. I was disappointed that the NightHawk app doesn't support my model, but I found a workaround with the Netgear Genie app."

"Connecting my Netgear modem/router to Xfinity was a breeze! I love that I can customize settings with the app, and I'm thrilled that I won't have to pay a monthly rental fee anymore. This purchase is definitely worth it!"

"After 58 days, my SB8200 stopped working. I replaced it twice, but both replacements failed too. A Comcast tech confirmed low SNR and poor signal. After a new cable was installed, the third modem worked perfectly. Arris support was fantastic throughout this ordeal—it’s some of the best I've experienced. I initially rated it two stars but have now changed it to five stars. I'd give them six stars if I could!"

"I found this modem easy to set up after downloading the app. It works well with Xfinity, and the payback was about 11 months compared to the $14 monthly rental fee from Comcast. Solid performance!"

"This modem does exactly what I need. I have it set up in a corner where the cable comes in, and my main Wi-Fi hub is centrally located. With six decos across my 5000 square foot house, I enjoy seamless internet everywhere. It's much better than an all-in-one unit, and I appreciate the flexibility to upgrade Wi-Fi without needing to replace the modem."
