Online games + spotify not connecting but browsers/downloads working well

Hello, I've had this problem for a few months since I have been home (I had this problem last December as well when I was back home) and have been looking for ways to solve it. I am not able to use spotify, play games online, or look at Steam/Origin's homepages (yet downloads still work with high speeds) and have looked everywhere for a solution. No games work online as well as other applications. This is not a problem when I am away at school, only when I'm home so I find it hard to believe it is a problem with me changing settings on my laptop.

The other computer in my house can play online games fine and no one else has problems with connecting their applications so there must be something wrong with my individual connection.

Thank you!
