Yes you can't have two wpa_supplicants fighting over the state of the
same wireless interface.
The "by hand" method for the WPA2 network -->
# service network-manager stop
# wpa_passphrase "Rice Visitor" > /etc/wpa_supplicant/wpa_supplicant.conf
(type the AP passphrase and enter)
# wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf &
(should associate after a second or two)
# dhclient wlan0
At that point you should have an IP on wlan0, default route and DNS
configured and workable.
For unencrypted AP "by hand", you don't use wpa_supplicant.
# service network-manager stop
# killall wpa_supplicant
# iwlist wlan0 scan
(find your AP, use its info below)
# ifconfig wlan0 up
# iwconfig wlan0 essid "Unencypted AP Name"
# iwconfig wlan0 chan 11
# iwconfig wlan0 ap 00:1F:12:34:56:78
(check if associated)
# iwconfig
wlan0 IEEE 802.11abgn ESSID:"Unencrypted AP Name"
Mode:Managed Frequency:2.462 GHz Access Point:
00:1F:12:34:56:78
Bit Rate=72.2 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
Link Quality=40/70 Signal level=-70 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:2 Missed beacon:0
# dhclient wlan0
Again your connection should have DNS, route and be workable.
If you're missing some of these commands make sure you have dhcp3-client
and wireless-tools packages.
