Here is an excerpt from this webpage: http://www.squidoo.com/motorola-s...ould-i-buy
However there are two main things that makes the SB6141 different from the SB6121. Most important of all is that the SB6141 has twice the download capacity than that of the SB6121. This is due to the fact that the SB6141 has the ability to channel bond up to eight channel downstream instead of four for the SB6121. The other factor is that the SB6141 is not only the latest of the SB61xx family but it is also slightly cheaper than its predecessor even though it has a bigger capacity
Who's got 343down/131up service that the sb6141 'puts out'? lol I agree that "the latest of the SB61xx family", but where is it cheaper than the sb6121?

No, it is a prepaid visa card, with a newegg logo on it. It is a rebate, the prepaid visa can be used anywhere visa is accepted.

The way I understand it, the fact that it can bond 8 channels means it will be able to better sustain a consistent speed than something that could only bond 4 or doesn't support bonding. You might peak better speeds on those others still.

Indeed. Basically with a docsis 2.0 modem you're driving on a one lane (one channel) road both ways. If that channel becomes congested, you're stuck. With the 6121 and docsis 3, you get four down and four up, if your cable plant is provisioned for that many channels. With the 6141 you get an 8 lane highway down and 4 up. Very little chance of getting stuck on a congested channel, and much more consistency and quality of service.

Look at the results. Bottom two are with the 6121 and the performance was extremely variable. My service then was 25/3, but I usually got variable pings and variable performance. From the 3rd from the bottom up is a 6141. Rock solid no matter when I did a test. You can then see where comcast bumped my speed for free, and I'm seeing a pretty solid 35/5 since then. The good numbers are even more impressive when you consider that the last two weeks have been spring break for the local schools and everyone is sitting home whacking away at the internet, not sitting in school all day.

Both the 6121 and 6141 bonded 5 downstream and 3 upstream channels, but when I took the old 6121 to my ex wifes house across town, it only bonded 4 down and 1 up, so YMMV. In a year or so, everyone should have plenty of channels.

Do note that some ISP's, particularly time warner, are getting bashed for not updating the firmware on customer owned modems, and some really old 6121's and some newer 6141's that have been sitting around a while have older firmware that in some cases disconnects periodically. TW will blame your modem and then install theirs to show you that it works and its your fault. shake head Comcast updated my firmware on provisioning the modem. Motorola will not release firmware for end users, stating that its up to the ISP to provide that. Looking at the 1 star reviews on amazon and newegg, most of them are from TW customers.

I bought the 6141 the other day from Ebay. I'm curious for when it arrives, how do I update the firmware with Comcast? Will it automatically do it or do I need to do something? Also, how did you go about getting a Comcast to boost your speeds for free?

I missed out on the Amazon deal on 3/31. I ordered the brown box from Amazon for $69.99. It's to arrive on 4/5. The technician from Comcast will be here 4/6 to install. Should I keep the Amazon's or return it for this one? Decision.
If I were you I would keep the one you have. Better to not have to deal with rebates. Also, no need for Comcast to come to you. Just call them and read off the MAC address to them and it will register with their network.

Comcast will do everything for you. You'll need the manufacturer and model (motorola sb6141), the serial number and the mac address from the label on the modem. Call them (the online activation tool has not worked at all for me for over a month) and they'll activate it, provision it, and send the latest firmware to it. You'll see the modem reset and blink its data light for some time while it downloads the firmware, about 2-3 minutes. You might want to break out paper and pen and a magnifying glass and write down the numbers. Unless you have superior eyesight, they used the very smallest type font on the smallest sticker possible. I have one modem with one character in the mac address that is so small its unreadable, so we had to guess at it until the modem worked....

You need to do nothing to get the speed increase. Comcast did it ~2 weeks ago. My 25/3 turned into 35/5, Not sure how that works if you're a new customer. And it may not have rolled out in your area yet, but when it does you'll get an email from them to power cycle the modem to take in the higher speed provisioning.

One interesting thing I noted while shuffling cable modems around. When I originally put the older SB6121 back into service at my ex wifes house but hadn't activated or provisioned it yet, its status page (usually locate at 192.168.100.1) showed it had bonded 5 downstream channels when the hardware is only supposed to support 4. I wonder if the 6121 and 6141 use the same hardware and artificially limit the 6121 to 4 downstream. Once comcast activated and provisioned it, it set to 4 down and 1 up.

Are prices on ebay usually about 65 for this? Quick research says yes, so I am holding off for now. I don't really need it for a little while and if it's a difference of 10 bucks I will wait. Thanks in advance
