Are they hiding something about the modem rental?
When I enrolled in Xfinity service, they suggested against purchasing a compatible modem. Their explanations included: the company’s protocol could change near year-end, limiting full bandwidth use; updates would require yearly purchases costing more than the monthly rental; and I’d need to handle security firmware myself. They also mentioned that newer Xfinity modems restrict features like mode changes, channel selection, and bandwidth adjustments. Previously, I managed those settings on an older device, but now they’re locked away. This affects my ability to configure a smart home properly. I’m weighing whether buying my own modem or sticking with Xfinity’s rental makes more sense, especially since I’m unsure if the bandwidth claims hold true for a self-installed unit.
I’ll purchase my own modem since the ISP’s equipment rarely delivers good performance. They primarily aim to sell their devices because they profit from it. You can achieve maximum speeds with your own gear as long as it matches their compatibility standards (they list speed tiers). I’ll buy a separate modem and router, which is usually more reliable and allows you to upgrade parts individually.
The US government mandates cable companies let you use your own gear at any time. Ignoring this would breach FCC rules. The representative might be making improvements. I understand that the "Gigabit" plan actually delivers around 1.4 Gbps, not the advertised 1.2 Gbps. Upload speeds are typically 35 Mbps, rising to 45 Mbps with extra capacity. Older Docsis 3.1 modems won’t reach these rates. Newer models like the S33 support a 2.5 Gbps Ethernet port, whereas older ones used multiple ports for aggregation. Regarding firmware, standard modems can’t be updated by users—only the ISP can do it. That’s why option three is accurate. You won’t be able to use their extenders or the advanced security features. If they keep pushing issues, file a complaint with the FCC.
