When I added internet to my cable, they came out and added a grounding
block, grounded it to my AC distro panel, put new terminators on my
RG59 home runs and installed a new 1:4 splitter. I asked them for a
75-100' cable so I could later run it myself through the ceiling to my
cable modem and they whipped up a cable, tested it and handed it to me.

They'll pretty much give you whatever you need if you ask nice has been
my experience.

Agreed.

Since cable companies don't really know how to respond to change
requests for existing customers, one tack for Drydem to take is to
move the cable modem to an outlet where it doesn't work, then call in
a service request indicating it's not working to the point they send a
technician out, and they'll get you squared away generally, applying
DC's appropriately as needed.

Dunno how many if any cable companies actually track where in your
home they installed the modem. The tech onsite will see that you made
your own ends perhaps, and that the cable might be wrong, but they
also might assume that the original installer didn't want to deal with
running new cable and that the homeowner might not have had anything
to do with it. Applying the right level of "I'm not sure what's going
on, but I'm hoping you can help make it work" along with being affable
generally gets you in a better place by the time the tech leaves.

"I moved my office, and needed the cable modem in this room, and
thought it was like DSL at my other office where I could just move the
the box to any other jack in the house."

the cable company won't want to make too big a deal of how cable modem
technology is more finicky than DSL, and they'll most likely do what
they can to make it work where you want your modem. They'll install
quality directional couplers and splitters and remake ends with high
quality crimp connections until it works, generally.

One thing to watch out for and not underestimate: tight cable bends.
I had a tight 90 degree cable bend back in a wall jack that turned out
to be the culprit of 9 friggin dB of signal loss. I couldn't believe
it myself. STraighted it out, redid the end and voila.
