How convenient, I was just looking at buying a modem to stop shelling out $8/month to cable provider. How nice that woot decides to sell the “updated” version of the surfboard for the same price as the one I have in my amazon cart currently.

Great modem. I am using it on Time Warner Road Runner and I haven’t even rebooted it since it was installed last August. It saves me from paying that dreaded monthly rental fee.

I’ve had the SB6121 for about 4 years now, and I have had ZERO issues with it. The SB6141 is ALMOST identical, with the exception of double the bandwidth capabilities. This is a GREAT deal. If I was looking for a new cable modem, I wouldn’t hesitate for a SECOND to get this.

Paid $100 for mine a year ago and change, never had any problems. Only had to restart a couple times due to power outage or whatnot.

Red light blinks all the time, but I hardly notice anymore. Works fine with my Airport Express router.

I did a bunch of research before buying because this is my first modem of my own, and I’m quite pleased with the result. This was well-recommended and it’s great with my Comcast service. Check your carrier to see if the device is compatible or not before buying.

Another review that states it’s compatible with Comcast, Time Warner, and Cox Cable:

Trust me, it’s better to buy a modem than rent one. Same goes with a DVR. :stuck_out_tongue:

The Wirecutter has had this model listed as their top choice for a cable modem since 6 January 2013.

I’ve been running one of these for about a year on Comcast, no problems so far. Not unusual to see over 6MB/s download rate through it.

Really on the fence since $16 more gets a new one with 9 additional months of warranty. what to do? what to do?

Will this manage an internet connection and wi-fi telephone service simultaneously? I currently have one modem for internet and another one for the phone service because the cable company was out of the newer modem which would have handled both.

Wow… I just ordered this last night from Staples for about $85 shipped… and my Staples order just shipped. That one’s going back the minute it gets here!

Granted, the one from Staples is new and would have a 2 year warranty (1 year warranty from Arris + 1 year additional from my credit card warranty extension benefit), and the one Sellout.Woot is offering today only has a 90 day warranty, but I’m not really sure that the extra warranty is really worth the additional $20. I got my current modem used from Ebay shortly after I switched to WOW back in Sept. 2011 and it’s still going.

In for one to replace my Cisco DPC2100R2 DOCSIS 2.0 modem currently on WOW Cable. This will give me an easier transition back to Time Warner since the SB6141 is on TWC’s approved modems list. I’ve had too many outages with WOW and had more reliable service with TWC.

The condition of these is stated as being “Factory Refurbished” on the item description page. Does this mean that Motorola has verified that each of these refurb modems is not active on someone else’s account at any cable company?

I guess I would be SOL if I try to activate this on WOW Cable and they say it’s already tied to someone else’s account?

This one is just simply a modem. It doesn’t have a built-in router or phone adapter. You will still need to use your current modem that provides your phone service.

I have Comcast for internet only. What will I have to do once I get this to get it activated with my account?

Call Comcast (or use the online chat, which which I did last time to do this for my girlfriend) and ask for a shipping box to be sent out to return the modem. It takes a few days and comes with everything you need to return it so all you need to do is drop it off with UPS (get the shipping receipt so you have the tracking number). Set up your modem (this particular modem is highly rated in Comcast’s modem compatability chart, so no worries - though you might have to try to activate more than once depending on your connection). Once you know they have the old modem, you have to call back to get it taken off your bill. The first time I had someone that was a pain in the butt and said I would have to cancel or renew the contract which is totally bogus (front line support are just there to make it as difficult as possible). Just ask for the retention department. Retention guys are way more knowledgeable and can do anything in the system (don’t have to bounce you around different departments) and their job is to make you happy so they’ve always been a huge help. They’ll knock it off your bill.

I have the Motorola SB6121 modem and I’m happy with it. It does its job well and was a big improvement over the Cisco Linksys modem I was running previously. Download speeds improved a touch and latency in games decreased about 20%.

If I could change anything on the SB6121 it’d be that freaking annoying orange light that blinks constantly since my router doesn’t have a Gigabit port.

If you have a compatible VOIP service, Obihai is a great option to go along side a modem like this. I have one for when I could use Google Voice (Google no longer supports 3rd party - sad).

Otherwise, if you use your provider’s VOIP (which are usually not compatible with an adapter - ie Comcast) and aren’t looking to switch to a different VOIP service, you should go with a modem that can support it. My girlfriend has Comcast voice so I got her an Arris TM822G modem, which is $136 on Amazon.

LOL me too. For the first month I thought something was wrong every time I saw it. I think it’s supposed to turn blue if connected to a gigabit port, so I don’t know why the orange has to be blinking :confused:

I am thinking the same… Got it in my amazon cart, and for that little difference, gonna go NEW :wink:
