The second problem is what another poster said, and that 11.2 dBmV downstream is too hot. The TW techs that came out to my house put a splitter in line with my cable modem with terminators on the unused ports when my levels were up around 7 dBmV! A two-port splitter will drop your downstream signal by 3.5 dB, which would help here. Your SNR looks good, as well as your upstream level. If you go with a splitter, ask for one from TW (they usually give them out without charge) because the ones from TW are somewhat better quality than what you find at Home Depot, and are good to at least 1 GHz.

As for the connection dropping - you want to look at your modem's log. If you're seeing errors such as "no ranging response received" or anything having to do with ranging response errors, these are significant problems that only a level 3 tech from TW can really diagnose. There are a bunch of reasons why it can happen, and frankly I wish I understood it better because before I had a DOCSIS 3 modem, I would have periods where my service would drop out all the time and I'd see these errors. Nobody at TW was able to figure out the problem, though, and I'm hoping now with a good cable modem and multiple downstream channels that all goes away (so far, so good!).

You may want to post your issue to the Time Warner Cable direct support forum instead of here. I've never tried this, but it's supposed to get you in touch with a TW cable tech who can help. I would say given what you've said here that there are issues that a competent tech should be able to start addressing right away.]]> http://www.dslreports.com/forum/Re-TWC-Modem-Problem-27685244 Thu, 01 Nov 2012 21:34:32 EDT http://www.dslreports.com/forum/Re-TWC-Modem-Problem-27684876 http://www.dslreports.com/forum/Re-TWC-Modem-Problem-27684876 Thu, 01 Nov 2012 19:40:34 EDT http://www.dslreports.com/forum/Re-TWC-Modem-Problem-27667977 With a 12db atten, you may have killed a separate issue affecting your service, not to +11db downstream level itself.]]> http://www.dslreports.com/forum/Re-TWC-Modem-Problem-27667977 Sun, 28 Oct 2012 10:25:07 EDT http://www.dslreports.com/forum/Re-TWC-Modem-Problem-27667678 this one).

A new modem will not fix this problem, but it could make it either better or worse depending on how sensitive the new one is to a too high power level.

It's a motorola sb6150 I believe with wifi built in but I turned it off.

The modem will lose connection at random times.

I called in and they said it was a power level problem, but couldn't be sure. A tech came out and said he didn't know what was wrong.

It'll work fine for a while, during which I get 20/5, then just randomly drop off.

How can I tell if it's the modem or the service?

I can fix it by rebooting the modem most of the time, even though I can ping the modem and see the login screen but I don't have the log in.

Thanks
