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 don't have a screen attached to the Pandaboard and I'm using minicom
over serial cable. Basically after boot I see:
> root@linaro-ubuntu-desktop:/boot# iwconfig
lo no wireless extensions.

[...]
After which there are several more similar connect-disconnect phases
and eventually the wlan firmware crashes and has to reboot.
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?
> root@linaro-ubuntu-desktop:/boot# ps -ef | grep wpa
root 2083 1 0 Nov15 ? 00:01:16 /sbin/wpa_supplicant
-B -P /run/sendsigs.omit.d/wpasupplicant.pid -u -s -O
/var/run/wpa_supplicant
Thank you!
