Motorola SURFboard SB6121 DOCSIS 3.0 Cable Modem for $57.99 + Tax @ Staples AC/PM

Quote from Sim-X : Anyone know where to get staples coupons? Can't find any on ejunkie

ebay? I think all these coupon sites got shut down.

I have performance internet from Comcast. Any thoughts on buying this smaller unit, the SB6121, vs the SB6120?

Quote from luckyyear2009 : I have performance internet from Comcast. Any thoughts on buying this smaller unit, the SB6121, vs the SB6120?

found this review on amazon comparing the 2

have tried both the SB6120 and the SB6121 and the signal levels and speeds were the same on both.
The SB6121 is a little smaller than the SB6120 but runs much warmer than the SB6120. Looks like they tried to cram too much hardware into too small of a space.

My SB6121 did not come with the power save button (it's listed as an optional feature), so about the only difference between the two models is the design. Both the SB6120 and the SB6121 use the same firmware: labeled SB612X.

So unless you want the different looking LED lights and a smaller and warmer box for a higher price, stay with the SB6120.

As far as speeds are concerned: the multiple channel bonding on these DOCSIS 3.0 modems is nice for sustained constant speeds. It also makes it easier for your ISP to enforce the speed cap if they choose to do so (Comcast in my case does). I was getting 20+ Mbps down and 3+ Mbps up on my old Linksys DOCSIS 2.0 modem, however that was the peak when the transfer first started, then it would taper off.
The DOCSIS 3.0 modem stays right at the 12/2 ceiling of my speed tier, but at least the speeds stay right up there and do not drop off after a few seconds.

Thanks for the help BrentH & repped!

Quote from tornadog : lol, I was going to order this and realized I had uverse @ home!

How is your Uverse Internet? I am switching from TWC to Uverse. I'm scared of the cap though! Can you provide some details on speed and reliability.

Thanks

Does anyone have a spare 25 off 75 coupon? I found they sell on eBay for about $6 but I wanted to ask here first. If it matters, I'm moving to begin graduate school and want to buy a modem for my new apartment. Just trying to conserve. Thank you.

Quote from PossumLodge : A modem is a modem is a modem. Even old DOCSIS 1.0 units will work, although the cable company will try to tell you otherwise to get another $5-$10 monthly out of you. As a former cable marketing guy, I can tell you stupid people renting them is a huge plus on the P&L. Simple math tells you you're into the black after 8 or 9 months when buying one.

This is exactly right. I literally just bought this item off amazon, paid the full 84.99...and I'm not even blinking in anger about having not checked SD BEFORE making this purchase.

The only thing that angers me is that I've stupidly/lazily spent many hundreds of dollars in modem rental fees when I could have done this years upon years ago. At the end of the day finally having taken the few seconds to find out which modem is rated best for comcast and buying it is the slick deal. When you talk about renting vs. purchasing...it has nothing to do with "is this modem better than that modem". I mean, I'm certain that this modem is "better" that your rental modem. That's just fact. Or at a minimum, it certainly isn't worse. And at 7 bucks/mo for rental...it'll take me one year to pay off the modem and make it a free/saving me money for the duration of my comcast life. Those on this SD can start realizing these savings in an even quicker span than that.

Did you sign up for just internet or a bundle? Trying to figure out how you got it for free.

I am signing up for a new account. Thanks!

Quote from leonimish : You still can get if FAR, just pay $13 S&H if you activate new internet service with comcast. I just signed up for this and having it installed tomorrow. For more details visit www.comcastoffers.com

Thanks for all the useful/helpful information by other SDers on here!

It's been backordered at Amazon for the past few weeks, but it's back in stock at $85.99. Not as slick, but still a great deal. Also, you can find coupons on the Bay for a little bit more (~$6), BUT BE SURE TO CHECK EXPIRATION DATE.

Travel back in time much?

Quote from Slercher : Just a heads up as a warning. Don't want to start any disagreement but want to share some awareness. We replaced our rented non-motorola modem with one of these and six weeks later (two weeks ago) began having problems. Our router got stuck in refresh mode. We've had three comcast techs out and we finally identified the issue. Motorola pushed a bad boot file out to Comcast for certain areas and comcast never caught it. If your router continually gets stuck refreshing, this is likely the problem. It will take comcast some time to fix it but that's what the issue was. To troubleshoot,' we've replaced our modem twice, router, then switched to a motorola 6120. The 6120 also got stuck in refresh mode. We then switched to a cisco modem and no issues whatsoever Don't waste a month having problems. If there's a loading issue and it's not from your signal, consider that you might have a bad patch from the provider. We went through alot before we got here. Just feel like I owe others for all the trouble we went through.

Quote from yazyazoo : I have been having weird issues with my Comcast lately. I have tried three different routers and they seem to get stuck and I have to power down all the components to reset the connection. I am using an older Motorola modem and a DDWRT router. I have tried three routers and they all do this after some time. What were your symptoms and what do you tell Comcast to do to fix this.

Quote from Slercher : We had three reps come out. The modem would get stuck in refresh mode after being locked on and drop off every two minutes. After confirming good signal strength, we swapped to a non-motorola modem after testing 3 non working motorola modems and it worked great.

There we go.

bump still good
