Need Advice on Cable Amp Install


I researched the below critical error I'm getting on my modem due to noisy upstream cable issues. I have no splitter, attenuater, etc.

I'd like to install an active return cable amplifier, but there is only one cable coming into my house from the outside junction box. I thought for the amps, you have to have one power cable and one data cable, so I need help.

Here's my error:
