These kind of installation problems are not rare.
TWC did the original installation here.
A few years later while troubleshooting a low signal problem they found:
1)Several corroded connectors from the street to the house
2)An extra unterminated splitter in their house mounted box.
3)Replaced an F connector in the wall plate fixture for the cable modem.
4)Replaced the cable modem.
A few weeks later they had to come out to replace the modem in (4) that
was a huge source of RFI. (Switching supply I believe). New modem was
quiet. I'm sure the replaced modem will end up in somebody else's house.

Make sure ALL of his cable drops are terminated at a piece of equipment or

through a cable splitter of correct impedance. Make sure all cable
splitters are turned the correct direction. Time Warner installed one
backwards in my house causing poor TV reception. Lastly, your cable
company has the option to "up" the signal strength at individual houses.
Perhaps your neighbor's level is so low as to be a problem.
When I had my house remodeled several years ago the electrician thought is
was OK to simply twist the cable center conductors and shields together and
put wire nuts on them. He did this in several spots. Needless to say he
got an earful from me.
