very few ISPs are still supporting 3.0. Do your homework.

No kidding… Echoing the above comments… I literally thought who TF would ever want this old technology. Who cares what it cost… You don't want it in my opinion

In my experience Xfinity will provision you 600Mbps with DOCSIS 3.0, so it's still useable for lower speed plans

No. That's why he said very few are still supporting it. This moden literally won't even connect to most ISPs.

Yep - even worse the ISPs are not keeping their modem website/compatibility lists updated. I found this out the hard way with 3.0 and Xfinity in Tallahassee recently. I'd recommend to use the latest versions of modems on the compatibility lists to avoid the hassle I went through.

If your ISP supports it, 600Mb speed and AC WiFi, and y'all crying? Yeah it's not top tier, but plenty useable for the bulk of houses.
