You can get any modem with a 2.5Gbps port, Jorge. The RT-AX86U Pro has only one 2.5Gbps port, it can host a Gig broadband line (with full bandwidth) but you won’t be able to have it on the receiving end due to the fact it only has Gigabit ports left and Wi-Fi is generally finicky—more here. As for extending the system, check out this post on mesh and related ones in the same series.

I recently upgraded to spectrums internet gig with speeds up to 1000Mbps. I also purchased a new router (RT-AX86U PRO).

What modem would pair best with my current setup? I would also like to extend the range of the WiFi throughout my home. Would it be practical to add a mesh system?

Thanks in advance.

Note: The product link goes to the Hitron Coda 56, not the Coda. For whatever reason the 56 is not recommended by Xfinity. It is compatible however. Looking at customer reviews, the 56 seems less reliable. The Coda is listed at $99.99. Also interesting. I’d been looking at the Coda on Amazon for awhile and a $15.00 limited time discount popped up.

👍

I haven’t tested it but it looks like a good deal if it holds up well. Good luck and keep us posted! Thanks for sharing, Mark.

I’ll answer my own question. Hitron Coda is recommended by Xfinity and is under $100. Doubled upload and download speeds from my son’s Docsis 3.0 modem. Easy setup and so far works great. Hopefully it stands the test of time. Good for up to
900+Mbps.

The Netgear CM1000 (DOCSIS 3.1) also doesn’t seem to be supported. The only Netgear modem that seems to be supported is the CM2000. I have a SMC1604 that is still working but gets only about the half the speed it should. (Supposed 150/20 plan) Any suggestions for an inexpensive modem that Xfinity will support?

Thanks for the input, LD. I guess Comcast is phasing out DOCSIS 3.0 and no longer accepting new activation. The one we have still worked with no issue or warning. Maybe it’s just a matter of time.

All modems will work with all routers or mesh systems, Pooja, as long as they use standard network ports (which the two you mentioned do.)

I’d not recommend Google Nest Wifi, though, but that’s a different story.
