Re: [Signals] New SB6121

I was wondering to about the high downstream values. In the summertime, the downstream stays near 0 to +4, and upstream stays near 42 to +47. This summer I had Comcast fix the high upstream issue. Before Comcast fixed the upstream, the upstream was in the 51 to 55 range. I guess when they "fix" the upstream it either increases or decreases the downstream depending on how they adjust the upstream.

Should the upstream and downstream values very enough so they need adjust them when the weather changes from cold to hot? Is there a permanent fix for more moderate change in the upstream and downstream values? It would be nice to not have to worry with the upstream and downstream values.

There are "AGC" (Automatic Gain Control) circuits in the line actives which compensate for seasonal ambient temperature variations. Perhaps one is malfunctioning.

I forgot to mention that we paid Comcast to extend their service to our home in summer 2010. I rely on the Internet for my job so it is important to have a reliable connection. ComcastSteve had a tech make adjustments to the upstream. Should I ask ComcastSteve to look into my levels again? Should I try the splitter first? If so, can someone recommend a splitter to use and where to install it? This is not my area of expertise. If possible, I would prefer Comcast to fix the issue.

Your signal levels look fine. I wouldn't worry about anything.

Are you having problems NOW?
It's pretty hard for them to fix something thats not broken, as well as being a bad idea to try.

I'm sure CCSteve could have someone look, but without obvious problems the trip might be a your expense, with no adjustments needed.
BTW is this a business account? because you'd get a quicker tech visit if it was and it went down/had problems.
Also, as nice as a remote home office is, if you REALLY need 100% up time, you'll need at least 1 alternete provider hooked up(or an alternete location) in case of a major (not just your local line) problem.

I decided just to monitor the levels for now. My connection has not had any disconnects yet, which is a good thing.
