Hello, My laptop has troubles obtaining an ip address on the wlan0 (if_iwn). The interface has trouble staying up during dhcp resolving. Below some information from logs. *If* it obtains an IP address it seems quite stable afterwards. Before https://svnweb.freebsd.org/base?view=revision&revision=300732 I had to reboot a couple of times before it would happen to get an IP address. If I need to supply more information please tell. I'm willing to test patches also. Regards, Ronald.
