I have a Rosewill RNX-N180UBE (with Realtek RTL8191SU chipset) that I want to work with Raspbian Wheezy (Raspberry Pi). Right now "lsmod" shows that the wifi driver being loaded is "r8712u", and apparently what I need is the "r8192cu" module. (based on this thread: http://forum.stmlabs.com/showthread.php?pid=17460)
I'd like to stop having the wrong module loaded, and get the right one to load, but I need some specific instructions on how to do it. I am not sure that the "r8192cu" module exists on my SD card.
