Hi All my CM1000 I bought in 2017 seems to be end of life, this past month I had to rent a Comcast all in one (I know) to rule out that it was the internet service but it definitely seems to be my modem at fault.
What would you guys recommend I replace it with? I'm limited to 1Gbps in my neighborhood.
Almost all 32x8 (capable of 1 gig) docsis 3 modems are going to be puma based.
No reason not to get docsis 3.1 unless you are truly cash strapped. That leaves the SB8200 if you're ok with 1Gbe ports, or the S33 if you want a 2.5 port.
My unpopular opinion.. Comcast's XB7 and XB8 boxes are fine hardware wise. If you're paying for unlimited data its literally cheaper to rent their modem with unlimited.
