Hi!
As the subject objects, i have noticed that when i switch to super high performance mode, the wifi stops working. A few weeks ago i was playing with aircrack-ng, i'll try to remove it and see if it fixes it. if not, may i get any help with this?
I use eeebuntu Standard 3.0 on a 701 SD.

Is there any way to fix this?

It's not aircrack, as I have that installed as well, and no issues.

Can you check the logs to see if there are any messages related to wifi? System->Admin->System logs.

i don't really know what is it i should look for due to my noobiness to linux, but i found these, hope it helps:
