[IL] Mediacom Cable Internet and Motorola SB6121 Modem

MaddChatter, I will be happy to look into the speed issues you are currently having. You can use the 6121, but unfortunately we do not offer any firmware for it at this time. Can you IM me your account or phone number and I will see why you are having issues?

I also recently purchased an SB6121 this week. Setup via walled garden and it has been getting around 30/3 on the 20/2 prime plus.

I've had a couple of recent problems (in IA) that suggest that perhaps my now ancient SB5100 is finally ready for retirement (although for the past three days it has been fine again).

The local stores no longer sell the SB6120 and none of the major e-tailers have it in stock now either, they all now sell the SB6121.
However, I understand that Mediacom doesn't (yet) officially support the SB6121?

MediacomChad:
Given that I've been using this SB5100 for 9 years now, it makes me want to be loyal to Motorola and get the SB6121, assuming this old SB gives it up soon, but should I instead look to get the Cisco DPC3008? The more research I do, the more I find that every model of cable modem has people saying it is the worst thing ever made (and killed their puppy to boot). I also see there is a DPC3010, but also not yet supported by Mediacom?

ivorygate, I am just wondering what modem issues you thought you were having. I am also in Iowa (Burlington), and have the SB5100. Last week I thought I was having modem problems too. I kept getting low receive levels and high upstream levels. Now the past 3 days have been back to normal.

On 8/30 and again on 8/31 I was having a problem where my modem was resetting itself about every 5 to 7 seconds. On 8/30 it happened at 8:25pm and lasted for about 10 minutes and then was fine for the rest of the evening. On 8/31, it happened again at 9am and lasted about 5 minutes.
However, on 8/31, after I unplugged my router, to reset it, it wouldn't come back on. I unplugged it several times and I think on the 6th or 7th try it finally came back on... um, that makes me nervous, thus why I need a plan on what to do here if it gives it up in the next few days.

Uh... ok, I don't know if someone is messing with me, but I kid you not, 5 minutes after I posted this, my modem just did it again...

It's alive, it's ALIVE!

Can you send me an IM with your account or phone number? I would like to look into this issue for you.

I did some checking and apparently Comcast doesn't play nice with this modem after a firmware update. Wonder if Mediacom has the same issue.

I have a SB6120 and am having frequent disconencts lately and am wondering if it is experiencing the same issue.

The 6120 is unsupported from our end at this time. It may work but we do not offer a firmware update for it

Chad, do you mean 6121? Becuae before I bought my 6120 I checked and Mediacom said it was supported.

That was a typo, yes I meant the 6121.
