I have Xfinity/Comcast and have had their XB3 gateway for quite a while. It delivers (wired and wirelessly) above the quoted speed for downloads (480 vs 400). However, upload speeds have always hovered between 11 and 13 gbps. I got an email from them that they would like to replace the gateway with a new one with higher upload speeds. (looks like an Arris? XP-7) Upload speeds are now averaging about 115 mbps, which is really handy for passing along large documents or sending them to the cloud. I don’t like renting from Xfinity. What modern gateways could I buy outright that would do this trick of higher upload speeds? I see this same gateway on Ebay, but every one is “not tested.” I prefer a gateway if possible instead of a separate modem and router because of the limited space I have for it. Thanks in advance for your help.

    Comcast only allows certain modems for the upload speed increases, any docsis 3.1 modem won’t do. It’s not the fact that some modems are better than others, it’s just what they allow, so the list might be updated to have more in the future. At the moment the only gateway device that is supported by comcast for the upload speeds the arris g54, which is 600 dollars, way too expensive in my opinion. The standalone modems are the hitron coda, hitron coda56 (I have one, it works good, 240mbps upload), and the netgear cm2050v. Yes, only 4.
