I don't know if anyone is having this problem with Killer Intelligence Center.

So, I just got a new extender and for some reason, Killer thinks the main router is the strongest router, despite not being the closest. This isn't a first time thing either, I got an extender for myself and even if it's right at my desk, it think the main router in the kitchen is the main router. Can anyone explain this, why and how do I resolve this?
