Cable Splitter Question

We currently have three X1 boxes (2 DVRs and 1 satellite), an Xfinity phone modem, and my own internet modem.

 

We wanted to add a fourth cable box to our service and I'd rather not have a tech come out if I don't need one.

 

The cable currently comes into our house and then hits a four-way splitter.  Three of the outputs go upstairs and the fourth goes to the phone modem which is pretty much right next to the splitter.

 

The TV we would be adding would also be in the basement very close to the splitter.  I am wondering if I should replace the four-way splitter with a five-way splitter or, split the cable going to the phone modem with a two-way splitter and use that for the new TV downstairs.

 

I really don't want to degrade any of the signals going upstairs and swapping out to a five-way splitter may do that.

 

What would be best?  Swap to a five-way splitter or split the cable going to the phone modem?  Or, should I just try splitting the phone modem cable and see what happens?

Find one of these and actually improve your signal to all equipment

Thanks.

 

We actually used to have one of these that Comcast put in but they took it out a few years ago because they said our signal was too strong.

Same thing different manufacturer.
If that’s the case add a 2 way splitter with one leg going to the Internet modem, the other leg feeding the 4 way, this would only affect lowering levels by 3.5 dB

"No such thing" followed by "it happens"... sounds like it does happen. I've had Xfinity reps tell me I don't know how many times that the signal is too strong.
