Comcast internet + TV issue

[mknabster]

I was helping a friend out with her Internet hookup in her apartment earlier this evening, and she had a peculiar problem. Let me let you know what her setup is first:

cable jack going to a cable splitter
one coax going to modem then another to the cable box
Then ethernet from modem to Cisco Linksys E900 router

So i was able to figure out what the problem was, the splitter. It turned out that it only splits and transmits the video signal, not the internet. So iw as able to figure out one of 2 problems, their internet works, but the cable does not. I think i'll have to go back to finish this off, but can anyone suggest what i can do so that their internet and cable work without them switching coax cables between the modem and cable box? Thanks

I've used splitters before cable TV and Internet before, no problems. Is this perhaps a powered splitter? What's the rating (MHz)? (fwiw, the one I'm currently using is 1000MHz)

I honestly can't saw the rating on it, i didn't take a look at it.
