you still have to have a Ethernet cable that is connected from your router or cable modem. Almost all come with ethernet ports from your internet provider. You need a ethernet cable for the length, then you need plug the cable into the modem or router that you have and into the adapter which is connected to your comper. Leave your wifi on so the driver can be found, you may have reboot, but if you see the internet is connected then you just need to turn off your wifi and make sure it works.
