every time i type in 192.168.2.254 in my browser it just says "oops" - while my internet cord is connected from my pc to the cube

The cube's ip adress is 192.168.1.254, will i need to change my pc ip address?

Not sure if my linksys router needs configuring or what  . I followed every single setup guide and the common factor in my problem is that i can not access the setup screen.
