DOCSIS signal improvement

Howdy all you network junkies. Gotta a very specific question about my cable internet signal levels and such.

My cox internet was just installed a month ago. The way the installer set it up was not very professional. He unhooked one of our TVs and ran it to the cable modem. And he did not do anything to split the signal elsewhere to restore the signal back to the TV he took it from (Very unprofessional, I know, but that's besides the point). What I have done is put a splitter:

The in port has the main coax line from the street. The 6dB out goes to the cable modem. The 2.8 dB out goes to another 4 way splitter which sends signal to the 4 TVs in our house. So...would it have been better to put the line to the modem on the 2.8dB output instead? I put it on the 6dB only because it brought the power levels on the downstream from +5 down to +3. I know 0 is the ideal number, but anything from -8 to +8 is good. By putting it on the 6dB output, it increased the upstream power levels from 35 to 40, so I know I have some signal loss there.

My question is should I move the line to the cable modem back to the 2.8dB output even though it raises the downstream power up to +5?

 

No one has any insight on this!?!?

 

I'd do it the same way you did it (sorry for not very elaborate answer- but that seems more logical way to connect it)

 

Aye. Unless you're looking at packet loss or something actually wrong, I wouldn't worry about it. It's not just your splitting that affects it, all kinds of losses and such in the line from your place to the box, etc., etc.

Like Downloads said... that's the best/only way to do it. Just make sure you use as few a splits as you can, and everything should work out alright.

 

Don't worry about it until connection and stability is hindered. if you are so worried about it pay the extra money to have them run a coax to the modem only if you are that worried about stability. I have like 3 tv's running on my coax that is hooked to my modem and I get very good stability, speed and ping. but yours by the sound of it is a splitter off the tv which sucks. just make sure that it has its own line to the large splitter and you are good.

 

Roger that. I'll leave it alone then.
