Here are some router ideas:
I’m checking if you’re using Comcast’s business class internet. They don’t provide regular modems for home connections. On the residential side they offer 1.4 Gbps down and 45 Mbps up, with some areas up to 2 Gbps and 100 to 200 Mbps up. That could explain why they sent a new modem. I’m not sure what speeds are available on the business side, but I know it’s very costly. The main concern is how much internet speed your router needs to handle. With Gigabit and multi-gig options, many routers struggle to support NAT at those rates. For a while, you had to use a PF-Sense box to get the most out of gigabit service. My advice for routers is to switch to Wi-Fi 6. It seems the standard has been established enough that it’s usually fine to invest in it.
I'm using an R7000 router with 802.11ac dual-band gigabit capabilities. The setup includes WPA/WPA2-PSK security. Everything appears to be in order. We've been connected through Comcast since they acquired our previous provider, and they provided a modem even before we started our business. Our current residential plan offers 800 Mbps down and 20 Mbps up—this seems more suitable than what you described for a business environment. There don't seem to be any other available options in the details we reviewed. At this stage, a router that matches our existing bandwidth is sufficient. No rush for a faster connection right now.
On the home end they offer just a single entry point. I’m certain we’ve been using Comcast since the early 2000s after they acquired our local service. Comcast ceased offering regular cable modems around the time of the Docsis 3.0 rollout. A gateway combines a modem and router into one unit. When people mention an ISP modem, they usually mean a gateway. Most US ISPs provide gateway devices, while Charter is the only one I’m aware of that supplies standard modems. Verizon is the sole fiber provider I know that offers a standard ONT. Here’s what equipment they currently list (https://www.xfinity.com/support/articles...userguides). Keep in mind none are typical basic cable boxes—this applies mainly to residential customers, while business users likely use different systems.
It depends on the codec being used. The slash symbol usually indicates a version difference—like Wi-Fi 5 (802.11ac) versus Wi-Fi 6 (802.11ax). I’m not sure what that means here. Ac stands for Wi-Fi 5, which is sometimes called Wi-Fi 6E in some contexts. The numbers you mentioned (4, g3, b2, a1) seem like a mix of standards and versions, but they’re not standard. It looks like Wi-Fi 5 was often seen as a step down rather than an improvement, compared to newer technologies. Marketing claims about upgrades might not always reflect real progress.
Alright, I got it. They delivered the "XFI ADVANCED GATEWAY (XB6)" to us.
By the time issues arise, Wi-Fi 7 gadgets will be common. It’s wise to get a used version of your existing router as a safety net. If it eventually stops working—whether soon or later—it gives you a backup option, allowing you to upgrade to a more recent model in ten years or beyond.
