Upstream Power SB6190

I just moved my modem to another room, and had to install a splitter.  I see my upstream power levels are right aroung 50dbmv now, as opposed to about 45dbmv before the move.  Things seem to be working fine, but wondering if this is still within spec?

Yes, barely. What type of splitter? 2,3, or 4 way? You should also note the downstream power

Re: Upstream Power SB6190

Here's a snapshot.  I have a Commspec amplifier outside the house that's connected via power from inside.  I also noticed that the green light on the Comspec amp doesn't appear to be on, however the one on the power adapter in the house IS on.

Hi @philco52

 

Thank you for posting your signal levels. It appears as if your Upstream Receive Power ann Upstream SNR is a little out of spec. I'd like to help get a tech scheduled if you're open to it. Is so, can you please send me a private message with your first and last name and the best day of the week to send a tech? To send a private message click on my name "ComcastChe", then click send a message.
