Comcast Cable Internet question

Specs: Macintosh
Can you split a single cable outlet between your
Comcast cable modem and Comcast cable TV set-top

I received the Comcast cable internet self-install kit
today. It came with a splitter, coax and the modem. I
attached both the cable modem and cable TV box to
the splitter, then the splitter to the wall outlet.

I popped the Comcast internet installation disk into
my computer, went through the install, it connected to
Comcast and had me setup a user account. After that
I could only access some Comcast sites, and nothing else.

I disconnected the modem from the splitter, and
connected it directly to the wall outlet. Since then, I've
been able to connect to everything.

I read elsewhere, on other message boards, that
others were running both from the same outlet. Was
this not true? Comcast's website says nothing about sharing an outlet with CATV, at least, not during the purchase process (only asks if you have a outlet within 20ft of computer)

I've been in the queue for Comcast support for about
25 minutes.

Thanks in advance.

BTW, I'm using Comcast's 30mbit "Ultra" cable internet and
digital cable television.

The modem is a Docsis 3.0 modem by Cisco
