In theory, premium home modems might enable quicker internet speeds, but ISPs are lagging in bandwidth availability. Expanding infrastructure remains costly, which explains why many still rely on wireless setups instead of traditional modems. I wasn’t fully aware of this since fiber connections don’t require a modem at all—I just use an Amazon router connected directly to my network box. Thank you for your time and clear explanation; it helps me grasp the challenges cable providers now face.
The faster the modem, the quicker the connections become. Even with a more powerful modem on a weaker link, performance remains solid since minor issues rarely impact overall speed. Cable Co shares the same frequency ranges as TV broadcasts and cell networks. Regarding uploads, Cable Co limits upstream traffic to 5 MHz to 42 MHz, which is quite restricted. Updates in Docis 3.1 should expand this capacity for better upstream handling. Being constrained by bandwidth is accurate—Comcast operates with roughly 100 to 300 nodes, each linked via fiber back to the company. While fiber supports substantial data transfer, actual throughput depends on the equipment at each end. I’ve heard some nodes only get around 10 Gbps, which explains why speeds drop during peak hours.
The reality is they found themselves in a tough situation due to self-interest. Many major ISPs received hundreds of millions to boost network performance, yet improvements beyond hardware upgrades remain limited—essentially offering free upgrades for new tech. Recently, they've simply increased their prices, making us even less competitive internationally. When examining profit margins for companies like Comcast and Time Warner, their high-speed internet profits stand at around 97%, meaning the cost to deliver that service is only 3% of your payment. The data limits they set aren’t about necessity but about extracting more from customers. For instance, if I hadn’t opted for the unlimited data add-on, I could use my connection nonstop for two and a half hours without hitting the 1 terabyte limit. This approach to data management in the U.S. feels unfair—they charge for speed while also charging per unit delivered. In theory, we should have tiered caps that reflect actual usage. Someone needing 150 Mbps works well with a 1 TB cap, but those requiring 400 or more will need significantly more than that. The issue is clear: greed drives decisions, not fairness. The solution would be to support higher upload speeds if necessary, but major cable firms prioritize profits over progress, slowing upgrades until it suits their bottom line.
It's odd you bring this up. Comcast recently added a fourth downstream channel to your cable lineup, but it stopped working about a month ago. It looks like this issue affected many regions nationwide. They seem reluctant to offer the upload speed, even though WOW provides 50 Mbps upload on most plans and doesn’t impose data limits. Instead, they’re offering only around 10 Mbps upload.
