I have an Atheros AR5B195 wifi card that actually works pretty good on Yosemite after a proper DSDT patch.
The problem now is that the card can't seem to discover any network when the computer wakes from sleep.
I have to restart the computer before the card can discover networks again.
I used a DSDT patch to make it work. I have also tried some injectors found here on this forum and OSXLatitude but they did not fix this issue.
Can someone please help?
