[zeshanch]

I have just installed successfully mojave. This is my first build. Ethernet is working perfectly but wifi does not work.
I have the TL-WN881ND wifi card. I have tried installing the IO80211Family and the AtherosWIFIInjector.kext but did not worked for me.

How i can get working with this card, please help!!

thanks in advance!!
