Re: [TWC] RR Standard with Motorola SB6141 Speed Increase?

No, you will not see a speed increase unless you're on a congested node. In fact, you'll most likely lose speed (assuming you currently have a D2 modem) as most TWC divisions do not allow Power Boost on D3 equipment.

I'm currently paying $52.99/mo plus an additional $10/mo for the old, no longer offered 15/1.5 "Turbo" upgrade; no modem rental fee.

Why did you say i will lose the speed? i'm on RCA DCM425 DOCSIS 1 modem that time warner provided for $2.50 per month.

So i shouldn't buy the Motorola SB6141 and it will be waste of money? Should i just keep paying $2.50 per month then?

Thanks

Like I said, you'll probably lose Power Boost if you switch to a D3 modem. »[TWC] No more perboost? A quick Googling shows that's actually a DOCSIS 2 modem.

As for rent vs buy, that's all up to you. I personally just bought a SB6141 even though they're not charging me a rental fee as I'm not getting Power Boost as it is and am planning on upgrading to the 30/5 "Extreme" tier soon and didn't want their crappy all-in-one gateway they insist on providing.

This is the first time I heard monthly fee $2.50 for internet modems in NYC area, I know I don't. If you are paying monthly fee for your modem, do not buy a modem instead go to a TWC local office and ask/exchange for a D3 modem, you deserve to have one if they are charging you monthly for it.

By the way, there's a new discussion about the Modem Fee going up to $3.95 per month. I've been eyeing the SB6141, and expect a 25-month ROI.
About the increased speed - here's how it works (correct me if I'm wrong).
Each cable channel gives you about 38 Mbps, and when you're tuned to one channel that's almost fully used, and another has open capacity, the modem has to tune to the other channel to use the available bandwidth. With DOCSIS 3.0, you can tune to 8 channels at once and get bandwidth from all of them, up to your 10 Mbps cap. I imagine that this would deliver more consistent bandwidth.
Also, you might not need the SB6141. It bonds up to 8 channels, giving you about 300 Mbps throughput. The SB6121 bonds 4, giving you about 150 throughput. If you don't think you'll ever want more than 150 Mbps during the life of the router, you just need the SB6121, which retails for $80 on Amazon.
You could also get a DOCSIS 2.0 modem, which are cheaper and most similar to the DCM425 and won't perform any better/worse, just make sure to get one that's DOCSIS 2.0+IPv6 certified. Now would be a bad time to invest in IPv4 equipment.

actually I would not recommend getting a DOCSIS 2.0 modem simply because they will probably EOL'd by the end of 2013 or 2014 the way things are going. TWC in Dallas already has bonding on the upstreams we are the third or fourth cluster to get upstream bonding behind NY, and Hawaii.

I am betting an upstream speed increase is in my future soon now that I am bonding four upstreams.

Sorry, the SB6121 is NOT approved by TWC. People have reported here that they were able to talk TWC into provisioning it for the Standard tier, but TWC will NOT provision it for use with the Extreme (30) or Ultimate (50) tiers. Either save your money and get a cheap D2 modem, or spend the extra $20 and get the approved SB6141.

Which is odd to me since both the 6121 and the 6141 use the same software versions, one would expect they would both run the same on the network. This is eventually what has allowed comcast users to start owning the 6141, since that model was never on their allowed list.

Are you sure about that? My (limited) research shows the 6121 uses a Broadcom chip whereas the 6120 and 6141 use a TI chip.

As far as TWC not approving the 6120 and 6121, I'm assuming it's an administrative prohibition. Even though it does bonding, it only bonds 4 channels. With 38 Mbps channels, someone on the Ultimate (50) tier will be using almost 50% of all 4 channels by themselves. That's not gonna play nice with D2 equipment also trying to use those channels!

From the 2nd page:
"Benefits:
Easily add the SB6141
to a deployed family of
SB6120s and SB6121s,
all three models utilize

Is there any technical reason for this? I was aware my 30/5 service would never have PowerBoost, but I didn't really care. But why should someone with a D3 modem provisioned for 10/1 standard service also lose this?

"Dear Time Warner Cable Customer:

As of Oct. 15, 2012 an internet modem lease fee will be applied to Time Warner Cable provided internet modems at a rate of $3.95 per month."

I live in brooklyn. F TWC. I am going to buy a 6141, not paying these thieves any more money.

No, no technical reason, they just have it disabled in the modem config file.
