ifconfig ndis0 scan ; ifconfig ndis0 list scan don't return with any
results, but if I run wpa_cli, and do a scan and scan_results it lists
the APs.
I applied your patch from the previous post and ran the following commands.
hp010# sysctl net.wlan.0.debug=0xffffffff
net.wlan.0.debug: 0 -> -1
hp010# ifconfig ndis0 scan
=== see ndis_dmesg2 ====
hp010# ifconfig ndis0 list scan
hp010#
hp010# uname -a

I was finally able to get connected to both my work and school
networks using the following wpa_supplicant.conf file:
network={
ssid="Home"
scan_ssid=1
key_mgmt=NONE
wep_key0=9123456c13800b19d3f8
}
network={
ssid="Work"
auth_alg=OPEN
key_mgmt=NONE
}
network={
ssid="School"
key_mgmt=NONE
}
#Settings from Windows XP profile for School_WPA
#Association -> Network Authentication = WPA
#Association -> Data Encryption = TKIP
#Authentication -> Enable IEEE 802.1x authentication for this network
= checked (grayed out)
#Authentication -> EAP type = Protected EAP (PEAP)
#Authentication -> Protected EAP Properties -> Validate server
certificate = unchecked
#Authentication -> Protected EAP Properties -> Authentication Method =
Secured password (EAP-MSCHAP v2)
#Authentication -> Protected EAP Properties -> Enable Fast Reconnect = checked
network={
ssid="School_WPA"
proto=WPA
key_mgmt=WPA-EAP
pairwise=TKIP
group=TKIP
eap=PEAP
identity="me at school"
password="password"
ca_cert=""
# phase1="include_tls_length=1 peapver=1 peaplabel=1"
phase2="auth=MSCHAPV2"
disabled=1
}
But I haven't been able to get it to connect to School_WPA (see
ndis_test, ndis_dmesg) when it is enabled. I had searched the net,
and found several hints that suggested to try various combinations of
peapver=x, peaplabel=y, and include_tls_length=1. But none of them
worked.
