Hi, I just finished building my computer but I am having problems connecting it to the internet. I am using a TP-LINK TL-WN821N 300mbps usb modem thing but I lost the cd so I got the drivers off the internet and transferred it onto the self-built computer via usb. So the drivers are installed but it still isn't recognising my tp link and when I go to connect to internet, in control panel, the only option is Broadband (PPPoE)
