I noted only one curve lit up on the connection while I'm at my parents house and decided to test it.

Something's wrong! I'm switching to the other one. I'll edit the results.
EDIT: MUCH BETTER!


My parents have 3 connections. An old one they don't use anymore, a main one and a secondary one. The first is the main one, the second is the secondary one. Looks like I'm using the secondary one today.
