Hello,

Jörg, I did what you told me, saw what the problem was and fixed it.
Then I compiled the driver.
The driver recognizes my device, but it has problems to find
my ISP:s access point (it has only succeded once). Is there some way to fix this? (mabye to modify the source code? it would be nice if I could set the ap:s address with "iwconfig ap ...") I know
that the ap is on 00:08:1E:01:00:4A

/Robin
