wpa_state=COMPLETED but still no ip on wlan0

[greanie]

I have been trying to get my wireless adapter to connect to my network. I have a Ralink 2571W wireless adapter that apparently works with the RT73USB driver.

I have build the appropriate wireless modules using menuconfig:

> find /lib/modules/3.7.10-gentoo/ -type f -iname '*.ko' | grep wireless

}

After getting the parameters wrong a few times, I finally got wpa_cli stat says I am connected
> wpa_cli stat
Selected interface 'wlan0'
bssid=00:24:93:60:e0:00
ssid=my-ssid
id=0
mode=station
pairwise_cipher=CCMP
group_cipher=TKIP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED

The wpa_state isn't always that stable during boot up. The wpa_state may say COMPLETED and when I try it a few seconds later, I get:
> wpa_cli stat
Selected interface 'wlan0'
bssid=00:24:93:60:e0:00
ssid=my-ssid
id=0
mode=station
pairwise_cipher=CCMP
group_cipher=TKIP
key_mgmt=WPA2-PSK
wpa_state=4WAY_HANDSHAKE


However, even when it seems stable on COMPLETED, I can't get an ip address.

> dhcpcd wlan0
dhcpcd[26932]: dhcpcd already running on pid 26866 (/var/run/dhcpcd-wlan0.pid)

Any idea what I have missed? Why doesn't it get an ip address? Is there a way to see which state the dhcpcd request is at?

rc-update show | grep -i dhcpcddhcpcd[/code] if you have dhcpcd in a runlevel get rid of it

Thanks for your ideas and feedback! I found my (n00b) issue. I was working command-line while getting wpa_supplicant and I had several instances of wpa_supplicant going simultaneously. When I tried to stop dhcp on wlan0, another would start it up again. I finally figured it out by doing a ps -ef | grep wpa. Once I killed the other processes, the wpa_state stablized and it was able to get an IP address!

Also, I was able to use the nl80211 driver and did not change to the wext driver.

Thanks again for your feedback. By trying to stop dhcpcd, I was able to find the root problem!!!
