You're going to need TWC out. the level at the modem is not adequate. The splitter arraingement is probably the culprit and I can't find that inline device anywhere in PPC's technical website. It sounds like a MOCA filter but has wrong markings on it.
You could try removing it and see if the upstream gives you 4 channels.
It looks something like this Idid end up removing it and of course my Speed test came out the same but I am still expericing the issue.... The Piece of equipment I am talking to looks alot like this
One end was connected to the coax and theo ther end went into my modem.
Edit: Also if I have to call in I know the technical support is gonna ask me to do the simple stuff is there anyway I could reference this Thread to let them know we have troubleshooted already?
I'll guess it's a Moca FilterBut that part number is way wrong... it should be a LP 1G C
..... If so, it shouldn't affect ahything below 1000 mHz where all the cable modem and TV channels are.
Repost the signal level page with it out.
If removing it didn't get the 4 upstream channels back, you need TWC out.
You shouldn't have a moca filter unles you have a wholehouse DVR setup.
Here are the upstream signals

You need to find where the splitter is and describe it... You have5 devices.. are there extra unused wall coax outlets? I have a feeling it's an 8 way rather than a 2 way feeding the modem and then to a moca filter then to a 4 way for the cable box/dvr's
Your upstream level is at the maximum and if it needs to go higher, you'll lose channels like the earlier post showed.
What you have is still unreliable.
There is only one Unused Coax Connection and that is in the master bed room.Our master bedroom has two coax connections.One is being used by my EHWH-DVR box and I have one playback in my kitcken and the other in my living room and in my study is where I have my modem.None of these are on an splitter and if the splitter is on the outside on the juncition box I think I may call TWC and have a tech come out.
