I have tried getting the proper drivers and installing them with ndiswrapper. Unfortunately, I can't seem to get it to work. The chip is the Atheros 5418, which according to what I've found, should require the ar5416.sys driver, with the net5416.inf and net5416.cab files. I have all these, but I cannot seem to get my drivers properly installed.

I try: sudo ndiswrapper -i net5416.inf
and get:
couldn't open NET5416.INF: No such file or directory at /usr/sbin/ndiswrapper-1.9 line 181.

Then if I type ndiswrapper -l I get:
net5416 : invalid driver!

Thank you very much in advance for your help.
