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.
