So our flatmates left and took the other router but I swear they tugged the connector too hard as I'm trying to connect to a different router we have but to me it seems like an issue with the connection itself as I have done everything needed to setup a new router. Here are the pictures of it, I don't think the blue part should be coming out like that right? We have a bunch of other WAN cables coming from the wall but only one seems to get some kind of connection which is the one that got tugged on. Like it seems like it needs to be redone and crimped properly.
