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

Thank you!
