Install TP-link drivers without internet

[vellamy]

Hi,

Today I have re-installed the debian image for A13-Olinuxino. Now, I want to have access to internet using a TP-LINK WiFi-USB. I know that this Debian image have the ath9k drivers I need because this WIFI-USB was working before in Olinuxino.
I am having a lots of problems to install it.
How can I install the WiFI-Usb on A13 Olinuxino without Internet connection? What commands should I write?
What step I have to do?

Thanks
