help with lag issues because of router

[Wolf12]

hey i recently got a new computer which is great but i have a higher lag than before. im sure its because of the router that i now have in my house.

my question is, is there any way aside from unplugging the router to lower my lag?

Play around with the router settings, what kind of router is it exactly?
