*Until last week* 4 Upstream Channels (6.4MHz ATDMA 64-QAM?) set in my Netgear CM1000 modem profile.
[All 4 6.4MHz Channels available WERE provisioned (DOCSIS RF 5-42MHz upstream ?]
(RF too noisy at low end to use full allocation 100% and/or legacy CATV stuffs at the bottom frequencies?)
Anyway...
NOW only have *3* upstream Channels and upstream "Channel ID" *numbering* scheme has changed?** Pic.
Implies either a 5th mini upstream channel add coming? OR new numbering for mid-split 5-85MHz capacity coming? OR ?
RF math (14.1MHz to 84.5MHz) "Channel ID 12" is DOCSIS 3.1 ?*mid-split numbering*? 5-85MHz
i.e. "Channel ID 12" is RF 14.1MHZ@low(-3.2MHz)
implied "Channel ID 1"@RF84.5MHz@top(+3.2MHz from center)
"Gigabit" service. 1000/35 Mbps (1200/42 provisioned per interwebs?)
SPEEDTEST to Comcast server [i.e. all Comcast network] ~11-14 ms. test to ~940(ethernet limit)/~40 NIGHT & pre-COVID. :)
During "work-school times" test ~14-20 Mbps upstream. :( FYI RF was and has been essentially perfect.
Overloaded (or nearly so) upstream during the workday pretty sure. : :uhh: Sometimes "glitchy" but not awful....yet.
Like some other Comcast markets apparently --- one can surmise we need a node split or something...
Xfinity App (a really good thing BTW) says: "To make sure your XFINITY services are performing optimally, we'll be doing some work in your area today. While we're working, you could experience brief interruptions to your service. We apologize for any inconvenience caused by our work."
This part of town is pretty low in "homes passed" I'd guess...wonder if this is a traditional "node split" or something else ....
We can always hope! Thoughts?
