Other suggestions in this thread are probably good, but I wonder about
something. For DSL, you have to have filters on the phones because DSL
uses sidebands. I'm wondering if cable internet doesn't do the same
thing. In which case, one question might be whether splitters and
repeaters and such actually capture the sidebands as well. For example,
if a component on the line effectively splits the signal but doesn't
respond very well in the area of the sidebands, you may have the type of
difficulty you describe.
Another thing to look at is whether you're getting a lot of dropped or
malformed packets as a result of this. A program like tcpdump or
ethereal might tell you that.
But in the end, I think the cat5 suggestion is the best. You can pull
the cable back from the office with a cord taped to the office end. Then
when you get it out of the wall, attach your cat5 to the package and
pull it back through using the cord. Now you have both coax and cat5 in
the office. And maybe not have to go back into the attic. ;-}
