Because docsis 3.0 standard is nearly 20 years old at this point and 3.1 is significantly faster. Docsis 3.1 is only 15, but 4 (which is still 8 years old) probably isn’t supported by your ISP yet. But the speed difference is quite noticeable. 3.0 will theoretically do 1gbps down, and 100-200 up, but 3.1 could do 10 down and 1gbps up. In the age of symmetrical fiber internet those upload speeds are dire. 3.1 realistically gets you a symmetrical gig connection.
I have a 3.1 modem but my ISP only has 3.0 speeds as far as I can tell. 1000/100 is their highest plan so the extra doesn’t really do anything.
My modem is 32x8 and I can see in the UI that only 4 of the 8 upload channels are actually bonded to reach that 100, which is half of the 200 that 3.0 can theoretically do.

Ah, so 3.0 is fine if your internet still sucks. Got it.

Exactly. So it’s great for xfinity
