Re: SB6141 Firmware Update?

So even with a different brand modem, Arris, you still see essentially the same exact error messages and disconnects?? Jeez.

What kind of signal problems did tech believe he/she saw? It sounded like the previous tech that came out had put your levels at near perfect.

It seems like there are a number of people nationwide having this problem. Maybe of their approved/leased devices, only 1 or 2 truly still work depending on area? Maybe it is something beyond a modem/residential problem?

I share your frustration as I am experiencing the same dropouts.
Please keep us up to date with any findings.


Well, the tech had put the levels at near perfect, because I had asked him to. When he was about to leave I was getting 7-8 dBmV down and 35 dBmV up, which according to him was in range and should be fine. Knowing that Motorola wanted closer to 0/40 dBmV, I asked him if he could tweak it and he added a splitter in to move the levels to closer to that.

When I started having problems last evening, I pulled the splitter out for a few hours, which included the time when I talked to the tech that saw the 'signal problems' which amazingly were the same levels that the tech was planning to leave them at in the first place. Regardless, I put the splitter back in, but continued to have problems.


I've also figured out that every time it happens I see this in the modem Error Logs.

Alright, I caught a crash in midstream and grabbed some screenshots. I started losing connection at 2:40 PM ET and saw two error messages in the log and then the upstream signal died. The modem then became unresponsive for a minute or two before finally reconnecting upstream with a bunch more error messages around 2:42.

It happened again at 2:46 and was down till about 2:48, again at 2:56 till about 2:58, at 3:05 to 3:06, at 3:31 to 3:22, at 3:35 to 3:36 and 3:39 to 3:40...
