Yuck on taking some time because it could be an underground cable. Maybe not.
A junction box (NID) wouldn't need to leak water to cause signal interference. After it rains, open it and check for dampness, loose connections, exposed shielding, damage, etc. Then find your neighborhood node and check for open panels, cracks, holes, damage, etc.
If you found nothing, it could be your underground cable. On the other hand, it could be a neighbor's NID or underground cable getting soaked. I suppose you'd need to rule out your cable first. Got a lawn sprinkler?
Thanks for the ideas, Bruce, but I live in an older section of town. No underground cable here. Only a drop coming to a plastic box on the outside of the house (Pretty well protected from the rain.) and then a short run of coax into the house.
This is good to know. If you don't feel it's your NID or cabling, I'd email Cox as per Allan's recommendation. Cox could check their runs.
