>Description:
I finally found time to work with Freebsd 8.0 release from last fall.  After struggling to find the correct configuration I was able to get my wireless interface working just great.  In an attempt to get Gnome 2.3 loaded I performed a freebsd-update to 8.1 prerelease.  After running install and rebooting twice the system booted up with the wlan0 device stating "associated."  However, no network response was forth coming.  After researching this on the web I found a blog that stated to insert the line synchonous_dhclient="yes."  I did and the network interface was able to perform pings and traceroutes.  But when I went to download a new package the network froze.  Again, I researched the web and found instructions to add if_vlan_load and vaps_ath0="wlan0".  Adding these did not make matters any better.  I then "rolled back" the Freebsd to 8.0 release and changed the conf files back and the network is up and running as expected.

8.0 release config files

rc.conf
wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP"

loader.conf
wlan_wep_load="YES"
wlan_ccmp_load="YES"
wlan_tkip_load="YES"

wpa_supplicant.conf
eapol_version=1
ap_scan=1
fast_reauth=1
#
network={
	ssid="my wireless AP"
	psk="my AP password"
}


>How-To-Repeat:
upgrade to 8.1 prerelease
