Re: [Gumstix-users] Problems with libertass / associating with access point

[S.R. M. <srm...@gm...>]

Hey all,

So, this issue has come up before and in troubleshooting it iv'e been
trying different prebuilt kernels, compiling my own kernel and modules,
etc... and im running into the following problem in almost every situation
where the libertas_sdio or libertas modules load:


root@overo:~# iwconfig wlan1 essid maddox ap 14:D6:4D:24:D8:1C channel 6

In the latest development kernel and rootfs, libertas loads about 5 minutes
after boot, and constantly outputs errors to the console BUT i can
associate with the AP using iwconfig wlan1 essid maddox.

So I'm wondering what's going on here - it looks like it's a driver issue,
since the only things that changes the behavior of whether or not I can
associate is the particular driver/kernel version loaded...

Any ideas? I've gotten the kernel modules/kernel compiled that I'd like to
use, with the 3.2.0+ image. No wifi would be a project killer though. I've
tried moving the device closer to the AP to eliminate signal issues to no
avail.
