hi,
sorry if this seem repeated or noob question.

but how is it the correct way to use ath0 wifi on this presario F762AU laptop?

btw, running FreeBSD 7.1 release here.

my /etc/wpa_supplicant.conf is like below
Code:
network={
 ssid="THESTAR"
 scan_ssid=1
 key_mgmt=NONE
 wep_key1=1234567890
 wep_tx_keyidx=1
}
i did the following with the hope to connected to wifi and ping www.google.com
Code:
# wpa_supplicant -i ath0 -c /etc/wpa_supplicant.conf
Trying to associate with 00:25:e9:e1:8e:88 (SSID='THESTAR' freq=2417 MHz)
Associated with 00:25:e9:e1:8e:88
CTRL-EVENT-CONNECTED - Connection to 00:25:e9:e1:8e:88 completed (auth) [id=0 id_str=]
then the console screen halt without giving me a # unless i do Ctrl + C.

i press ALT + F2 to start another console screen
Code:
# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 00:1f:4a:9e:d9:25
inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/36Mbps)
status: associated
ssid THESTAR channel 2 (2417 Mhz 11g) bssid 00:25:e9:e1:8e:88
automode OPEN privacy ON deftxkey 2 wepkey 2:40-bit txpower 31.5
bmiss 7 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250
roam:rssi11g 7 roam:rate11g 5 protmode CtS burst roaming MANUAL
i suspect i don't get the IP address.
but.

in etc/rc.conf
i already specified.
Code:
ifconfig_ath0="authmode open wepmode mixed DHCP"
my boot/loader.conf is like below
Code:
if_ath_load="YES"
wlan_scan_ap_load="YES"
wlan_scan_sta_load="YES"
wlan_wep_load="YES"
where could be wrong??? clueless..

i actually manually launch the dhclient ath0 before, but it doesn't works.
Code:
# dhclient ath0
DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 3
DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 7
DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 13
DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 13
DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 9
DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 9
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

hiredman in ##freebsd freenode.net helps me solved this problem :)
!!! very big thanks to him/her (God knows)

so.. suggested step is like below.

remove the
wlan_scan_ap_load="YES"
from /boot/loader.conf

then change
wep_key1=1234567890
wep_tx_keyidx=1
to wep_key0 and wep_tx_keyidx=0

coz.... we are using the first key on the wifi router.

/etc/rc.d/netif restart ath0

and you got it !!!!
very big thanks to this samaritan.

I have a wireless problem with d-link g520. (I hope I have not missed anyting obvious in the handbook)
From what I understand this device is supported. The card is does not transmit anything. I get not arp tables, my pings do not go out etc nothing...
The card works on the same computer with debian and netbsd.

Card: D-Link DWL-G520, H/W Ver: B4, F/W Ver 4.40

The data are: Freebsd 7.1-release
Code:

Other computers in the network does not see my pings, but when they ping me I get their arp entries. But even after this I cannot transmit anything.

From your ifconfig:
"...authmode OPEN privacy ON deftxkey UNDEF wepkey 1:104-bit txpower 31.5..."

How did you set up WEP?

cheers,

Thanks,
I am sorry for the late reply, perhaps it was the wepkey. I am using wpa_supplicant now and it is working. I configured the wepmode about the same as in netbsd, with ifconfig nwid XXXX nwkey YYYY, and the wepmode was on.
It was weird that I got their "arp-info" when they pinged me, but they could not see anything from me. Perhaps it is possible to get that arp info without being properly "associated" with the network.

But no luck with authpf :\
