I dont know how to install or set up my linksys how do i do it

Is this the first time you will install it or was it edited before? If this is the first time you will set it up, then follow these steps. If in case that you have configured it before and you cant remember the password and username as well as the direct link to your router GUI then you can just hard reset the router by looking at the back of the router, you will see a reset button. You will need to push it hard enough for at least 15 secs before you release it and then powercycle the router afterwards. After that, follow these steps on this link: http://www.columbia.edu/acis/networks/aptnet/linksys/index.html
