Hi All,

iwn0: iwn_read_firmware: ucode rev=0x12a80601
iwn0: iwn_intr: fatal firmware error
firmware error log:

iwn0: iwn_panicked: controller panicked, iv_state = 1; resetting...
iwn0: iwn_read_firmware: ucode rev=0x12a80601

After that I've destroy wlan0 and start /etc/netstart, after that wlan0 get status: associated but ip was 0.0.0.0 ;( I've again destroy wlan0 and get:
