[gentoo-user] wpa_supplicant and at&t 2wire gateway

[John Blinka]

I've recently subscribed to AT&T's u-verse which came with a
2wire 3800hgv-b wireless gateway.  On the windows side, my
dual-booting Dell laptop picked up the signal and connected
trivially.  I've had no such success on the linux side.

The gateway claims to use WPA-PSK authentication and TKIP
encryption.  My supplicant.conf file looks like:

ctrl_interface=/var/run/wpa_supplicant

network={
                 ssid="my_ssid"
                 psk="my_password"
                 key_mgmt=WPA-PSK
                 proto=WPA
                 pairwise=TKIP
}

wpa_gui provides the following information for a few seconds:

adapter:          ath0
network:  0:     my_ssid
status:             SCANNING
last message:  Disconnect event - remove keys
authentication:
encryption:
ssid:
bssid:
ip address:

then displays:

adapter:          ath0
network:  0:     my_ssid
status:             4WAY_HANDSHAKE
last message:  ASSOCIATED WITH 00:22:a4:0d:23:89
authentication: WPA-PSK
encryption:       TKIP
ssid:                 my_ssid
bssid:               00:22:a4:0d:23:89
ip address:

and then cycles between these two sets of information.

I can't pretend that I understand what's going on, and I haven't
found any enlightenment in web searches.  Does anyone know
what this means, where I'm stuck, and how to go forward?

Thanks for any help,
