Review: Easy with Xfinity - Super easy setup with Xfinity. The Xfinity app did it all. All I had to do was connect it, turn it on and scan the label on the box in the app. Unboxing and the physical connections took longer than the network setup. Review: Bit of a battle to get up and running. Does not include wifi. - It took me a while to get it to actually get online and working with Xfinity and the network I have setup in my home. I needed to go online with my cellphone and go to the activate a new device page while just my computer and the new modem were networked together. Once it was activated I had to reboot the modem and it then went online and was networked into my computer and online. Then I had to get my wifi router passing the internet from the new modem which took some time. I reset the automatic DNS selection settings and that got everything working together so all my network devices got online. Since then everything has just worked including the phone lines and it's fast. It's a nice fast cable modem with telephone voice support, just be prepared for some work to get it setup and working properly if you have a complicated network with a lot of devices to work with. ## Features - BUILT FOR FASTEST MULTI-GIG SPEEDS: Best for cable provider plans up to 2.5Gbps. - COMPATIBLE WITH XFINITY INTERNET & VOICE SERVICE: Certified by Xfinity and ideal for Xfinity’s Triple Play plan.

The CM1200 has four ports, the CM1000 has one. **Q: With the cm1200 and xfinity residential cable internet, can you use one wan port to your computer for a direct connection and on wan port to router?** A: Both the CM1150V and CM1200 have 4 Ethernet ports. That does not mean you don't need a router. These four Ethernet ports support future multi-gig services by using link aggregation and two or more different IP addresses. The CM1100 has two Ethernet ports for the same purpose of future link aggregation. If you want a multi-gig cable modem (2.5 Gbps) without the need for aggregation, you'd like the CM2000 or CM2050V with XFINITY voice support. I know NETGEAR does not do a very good job explaining this to potential buyers and I hope this helps someone. CM1100 - https://amzn.to/3peEGGR **Q: So, up to 2gbit modem with - drumroll please - 1gbit network ports. not 2.5gbit. which engineer was responsible for this fail?** A: which "engineer"? It was probably "beancounters" in marketing. this CM1200 model has 4 ethernet ports. but only 2 are functional. the first 2 ports can be Link Aggregated, to get downloads up to 2 Gbps. the other 2 ports are mere decoration to trick naive trusting people to buy this model. not to overlook, Netgear only certifies this model to 800 Mbps with Xfinity. that's what it says here in the ad. (and also on Netgear website) **Q: Can I replace my existing cable modem from Spectrum with this, on my own/ without a service call or having to call customer service?** A: Replacing your modem does not require a service call, but you will need to call Spectrum customer service, as they will need to activate the modem as an authorized device on their network before it will be able to lock down a connection. You will need to provide them with the unique MAC address of the device - specified on the modem's label. Customer service calls can be irritating, but when I did the same a month or so ago, the tech knew what needed to be done and the entire call, once speaking with the tech, lasted about 5 minutes - little hassle...this time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy with Xfinity *by D***V on February 15, 2026* Super easy setup with Xfinity. The Xfinity app did it all. All I had to do was connect it, turn it on and scan the label on the box in the app. Unboxing and the physical connections took longer than the network setup. ### ⭐⭐⭐⭐⭐ Bit of a battle to get up and running. Does not include wifi. *by T***Z on June 23, 2022* It took me a while to get it to actually get online and working with Xfinity and the network I have setup in my home. I needed to go online with my cellphone and go to the activate a new device page while just my computer and the new modem were networked together. Once it was activated I had to reboot the modem and it then went online and was networked into my computer and online.

I purchased the NETGEAR Nighthawk Multi-Gig Cable Modem for Xfinity Voice (CM2050V) on October 21, 2025, paying full retail price ($299 + tax). The unit received was clearly used, improperly packaged, and security-compromised. Evidence of Prior Use (Not New Condition): Outer box was torn, unsealed, and forcibly opened Device surface had grease marks and fingerprints Power cable was loosely thrown into the box Missing required accessories: Installation documentation Ethernet cable Telephone cable All other items in the same shipment arrived factory-sealed and new, making this discrepancy unmistakable. Functional & Security Defect After installation and ISP MAC registration, the modem becomes operational; however, the administrative credentials cannot be reset: Factory reset procedures do not restore default credentials The default admin password (“password”) no longer applies Admin password cannot be changed or recovered This indicates one of the following: The device retains prior owner credentials, or The reset mechanism is non-functional Both conditions render the modem defective and insecure. A consumer networking gateway that does not allow credential control is not fit for purpose and presents a security risk. As a Network Infrastructure Engineer, I can state unequivocally that a modem in this condition fails basic security and usability requirements. Return Window Impact: This modem was shipped directly to Texas for an elderly family member. Due to an unforeseen family death, I was unable to install the device until November 26, 2025, at which point the return window (November 22) had expired. The defects were discovered immediately upon first installation. Conclusion: This is not a matter of buyer error or preference. It is a case of: Used hardware sold as new Incomplete contents Security-related functional defect At this price point, and for a foundational network device, this is unacceptable. Amazon must ensure that items sold as “New” meet minimum packaging, reset, and security integrity standards. I will follow-up this review with a formal Executive Escalation letter to request escalation regarding this defective and misrepresented product sold and shipped by Amazon as Brand New. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/230590441-cm2050v](https://www.desertcart.kr/products/230590441-cm2050v) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-29*
