Excellent modem for gigabit speeds
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Setup was super easy — I had the Motorola B12 DOCSIS 3.1 modem up and running in about 15 minutes. It connected right away with my ISP and has been fast and reliable ever since. Streaming, gaming, and video calls all run smoothly with no lag or drops. The 2.5 Gbps Ethernet port is a huge plus if you’re on a gigabit or higher plan. Speeds are consistently strong, and I like that the design is compact with just a single status light (cleaner look than most modems). Keep in mind this is modem-only — no built‑in Wi‑Fi. You’ll need a separate router, but that gives you flexibility to pair it with whatever system you prefer. --- Pros: • Fast DOCSIS 3.1 performance with 2.5 Gbps port • Easy setup with major ISPs • Reliable connection, low latency for gaming/streaming • Sleek, compact design • Saves money vs. renting a modem Cons: • No Wi‑Fi (router required) • Only one Ethernet port --- Bottom line: If you want a future‑proof modem that delivers top speeds and stability, the Motorola B12 is a great buy.

Great upgrade from 1 Gbps Modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I got this modem to replace a 7 year old modem that has been disconnecting intermittently (CM1000). With a 1 Gbps speed with Spectrum as service provider I am able to reach up to 1.1 Gbps with this modem. The CM1000 is rated at a 1 Gbps and it went up to as high as 940 Mbps. This modem looks like a mini speaker and it's super light. It can easily fall over if the coax cable is not situated in specific angle. So far I have used it for one week and no issues with internet speeds using it along side eero 7 Max mesh system. It's a great modem for those who need up to 2.5 Gbps speeds.

You need this modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This modem is amazing. I get nearly double the internet speed I am paying for. That's what this modem is all about. This next part I had to find in a blog and confirm it with motorola: "Active Queue Management (AQM), helps organize data packets to reduce latency and improve streaming, gaming, and conferencing performance." Yeah especially for the price, you get what you pay for. Its compatible with most internet providers as well.

Works well but runs hot
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Appears to work fine. Not easy to get connected to Xfinity. Had to go through chat to get it connected and even then they had to have someone call me back to get it to connect. My old modem connected automatically with no interaction from Comcast needed. This thing runs super hot compared to my old Motorola modem. Even the cable connector gets super hot. Ended up returning because of that.
