Comment 2 Wormo (RETIRED) gentoo-dev 2009-07-30 23:37:45 UTC
Would you mind booting to your old kernel that worked, and verify that it still works with the upgraded wpa_supplicant? If the problem does turn out to be caused by the kernel upgrade, please post 'dmesg' output for both the working kernel and the broken kernel.
Comment 3 Brayan Arraes (YacK) 2009-08-14 15:48:19 UTC
have you tested with the newer kernel version
gentoo-sources-2.6.30-r4
if yes post dmesg, with the newer kernel and newer wap_supplicant, if no, please, do it
