New Modem
It seems like you're expressing frustration about limited options in your area. Just remember to stay clear and respectful.
I'm trying to confirm if there are legal requirements for this. The fee of $15 per month seems unclear to me—what does it cover? I wasn't expecting to pay that regularly. I was planning to buy any available option, but I'm unsure if Xfinity supports all models. It's not a big deal since we already have a home phone, though smartphones are more popular. My upload speed is around 20-30 Mbps now, so unless a specific modem improves performance, it shouldn't be a major issue. I've never quoted many people in one chat, which might explain the quick replies.
There are devices that can enhance performance. The Unifi UCI supports upload speeds exceeding 40 Mbps. It's unclear what most users require in terms of upload bandwidth, but I believe plans with substantial downlink and uplink capacities would be ideal. This is why @Donut417 mentioned DOCSIS—it represents the newest technology, promising much faster upload rates than typical U.S. standards (40 Mbps or less). In certain locations, speeds will be symmetrical, providing equal download and upload capabilities. Comcast maintains a catalog of compatible modems and their supported speeds. I'll retrieve that information and share it here.
We enjoyed 10 Mbps for years before getting a upgrade to 20 Mbps. Yet in Mid Split zones faster packages offer 100 Mbps while premium tiers provide 200 Mbps, as I remember. Demand for uploads has risen since everyone now relies on cloud-connected security cameras, and safety concerns have grown. Many individuals work remotely, which adds more traffic. Cloud storage is common, and some of us run media servers that need access on the go. More folks are working from home, etc. Motorola ceased operations a long time ago; Google acquired them and significantly altered their direction. Arris introduced the Surfboard Name, and it seems Zoom took over the Motorola branding. Let me clarify a few points. Docsis is the protocol cable providers use to deliver internet through their hybrid fiber/coax setup. Most users rely on Docsis 3.0 or 3.1. Docsis 4 represents the latest version. Cable internet fundamentally depends on radio waves, similar to WiFi, but it stays confined within a cable network. Historically, upload speeds range from 5 MHz to 42 MHz, which has limited bandwidth and contributed to slow performance. Mid Split and High Split enable higher frequency usage, boosting speeds. Comcast has opted for Mid Splits, so in those regions uploads typically see 100 to 200 Mbps. The challenge is that only certain Docsis 3.1 modems support Mid Split, meaning without one, you’re limited to around 40 Mbps depending on your plan. I own a Netgear CM1000v2 which supports 940 Mbps down and 40 Mbps up – it functions properly.
You're asking about how you can achieve around 600 Mbps despite the mid-split system's limitations. It sounds like the issue is with the hardware setup, and a third-party modem might offer better performance than the standard Xfinity or Comcast equipment. You're also considering a Netgear model or similar for higher speeds.
Your download rate is being mixed up with your upload performance. The midpoint applies only to uploading. Traditionally, coax connections have struggled with speed consistency. On the download end, your limit is mainly the Ethernet port speed on your modem—Gigabit ports usually cap around 940 Mbps, though 2.5 Gbps ports might exist but are rare. Most providers offer up to 1.4 Gbps, so higher speeds are uncommon. Remember, these numbers reflect download capabilities, not upload performance.
