TP-LINK has a great web site and cool wireless router simulator. You did not say what model of router you have, however first you need an eithernet cable from the router to your computer. Then open up a browser window and type in the address 192.168.1.1 , that should bring up a tp-link window. Once your in there go on the left side and click on wireless settings. change your SSID as an option but definitely checkmark were it says " Enable Wireless Security" and have at least min. WEP. Computers in the future may have only 1,000 vacuum tubes and perhapsonly weigh 1 1/2 tons. ~ Popular Mechanics, 1949~
