|You should be able log into the router's Admin settings and enable your wireless settings from there. Typically, you can access this section by using your web browser and going to 192.168.1.1 then supplying Admin as the username and either password as the password or leave that field blank. You may have also modified these at an earlier time.|
If that IP address isn't correct for your router, open up Command Prompt (Start > Run > type: cmd) and type in ipconfig /all Look for an IP address next to Default Gateway and that is your router's IP address.
If you can't gain access to the Admin settings, either consult your router's manual for the default login settings or find the tiny button on the back of the router and press it with a paperclip for 30 seconds. That will reset all the defaults for the router.
