Update: I bought an Atheros 5008 wifi pci-e. When I put it into my Acer 6930 nothing happens. It doesn't matter weither I put on iAtkos, iDeneb, or Snow Leopard the airport doesn't show up.

I used a guide from someone who installed iAtkos and Snow Leopard on an Acer 6935g and got airport without any problems.

Also in his guide others with 6930 had the same network problems I am having but there was never a solution given.

If someone could please point me in the right direction, I would really appreciate it! I will run any test needed.
