Check the lights on the router if it's on, access the admin page of your router and make sure that the SSID or wireless name is being broadcast, try changing the name if you are using the default one to easily distinguish it... If other wireless computer can detect your existing wireless network then I would suggest you to check on the computer if the wireless adapter is enabled and detect wireless networks available
