My desktop machine exactly has the same issue. I use a 94360CD wi-fi + bluetooth 4.0 card. Hope unchecking wake for network access would fix this issue. I would try it tonight.You guys are the BEST! I could not figure this out on my CustoMacPro desktop. I was having the exact same issue. Disabling the wake for network access in Energy Saver worked perfect!
I have a apple native wifi card, installed with an adapter. And I had the same issue! After sleep, the ping is really unstable, 100ms or 200ms delay to router with 10% packet loss. Disabling wake on wifi solved the problem! But I don't know why this happens to apple card as well..Yes. Hackintosh is full of compromise.
Not that I know of. The problem is relatively pervasive, probably caused by slightly incompatible hardware.
If you can find room in your laptop, you might be able to install Apple native hardware with an adapter...
