am I ridiculous for thinking about buying a DOCSIS 3.1 for a 75/15 connection?
I'm having a double nat problem with my comcast business SMC cable modem. Their tech support guy basically said it is a pain to get & keep the SMC in bridge mode. He recommended that I just buy my own modem. I'm not going to get a discount since the voice goes through a different modem & they are charged as one fee. I have a staples credit & can get the $110 off the Netgear CM1000. This will connect to an Orbi (two satelites - on wireless backhaul, because, you know...) which then connects to a netgear GS724Tv4 switch. I have four workstations, two printers, a ReadyNAS business pro & an Apple TV hard wired. It's a home business so then there is all of the wireless traffic of a typical home with teen+ kids.
Should I just save the extra money & get a CM600 or CM700 instead of the CM1000?
@jbruce I think everyone should buy a DOCSIS 3.1 modem right now for one simple reason: Buffer Bloat protection. Cable Labs mandated that all DOCSIS 3.1 modems use the new DOCSIS PIE queuing algorithm which almost completely resolves the Buffer Bloat issues that existed in all prior DOCSIS modems.
And, it doesn't only apply to 3.1 connections. All connections made by a DOCSIS 3.1 modem will use the new queuing.
Maybe the quesiton is, whether buffer bloat will affect you. We all know Dave has a family that slurps data in both directions as if it is unlimited, and based on his internet connections, it is.
I'm sure Dave will correct me if I'm wrong, but Buffer Bloat is where lots of data being uploaded, clogs the up-link channel so that things like ACK's for downloaded packets cannot be sent so the next chunk can be downloaded.
If you are not in the habit of uploading lots of stuff, such as vacation pictures from 4 family members while you are in the middle of recording a podcast, I'm not sure Buffer Bloat is going to affect you, especailly if it has not been something that has annoyed you to date.
Basically look at the cost of the DOCSIS 3.1 vs the DOCSIS 3.0 modem and figure in 2 or 3 years the price of the DOCSIS 3.1 will drop to the current prices 3.0 modem and ask youself if you will save money overall by buying a 3.0 today and a 3.1 in 2 or 3 years.
A) I have an eero, so I cannot complain about Buffer Bloat, but in truth, I never really noticed it before either (I mostly worried about as an academic issue, but not because it was an issue).
B) The Arris DOCSYS 3.0 VoIP based modem cost me $65 vs a Netgear DOCSIS 3.1 VoIP modem cost $230 on Amazon. Because I needed VoIP support, the DOCSIS 3.1 was 3 1/2 times as expensive. It was worth it to me to wait a few years before getting a 3.1
The prices for non-VoIP DOCSIS 3.1 modems is less, so your math may come out different.
