Subject: trouble using wifi on Linaro Ubuntu for Pandaboard
Hello,
I'm having trouble connecting to wifi on the Linaro Ubuntu releases
for the Pandaboard. I've tried with both 12.10 and 12.09 releases,
which are listed to have passed the wifi test.
...
I'm using Pandaboard with OMAP4430 and wl1271 wlan chipset.
I've also tried running wpa_supplicant manually to connect to both the
same open network, or another one secured with WPA2 (I used the
wpa_supplicant.conf from an Android phone so I'm pretty sure it was
correct) and I have the same issue. There is also a wpa_supplicant
always running in the background, does it matter?
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

Link Quality=40/70 Signal level=-70 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag: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.
