View Full Version : [ubuntu] Wireless troubles after upgrading to 8.04 LTS

May 13th, 2008, 05:12 AM
I upgraded from 7.10 to 8.04 LTS the other night, and now I'm having some trouble connecting to my AP. I had to boot an older kernel to get online. Any help or general direction pointing would be greatly appreciated. :)

Here's a sample of dmesg (larger dump attached):

[ 113.608000] wlan1: hfa384x_cmd_issue: cmd reg was busy for 5000 usec
[ 113.608000] wlan1: hfa384x_cmd_issue - timeout - reg=0x8000

[ 113.612000] wifi0: hfa384x_get_rid: CMDCODE_ACCESS failed (res=-110, rid=fd51, len=6)

Here's the output from 'lspci -vvnn' for my adapter:

Let me know if anything else is needed

It seems to be a driver problem especially when you say that switching to other kernels makes it possible to connect. Have you installed the backport modules?

Thank you for the responses!

Unfortunately, there seem to be no prism modules running when I boot into the latest kernel on my system (2.6.24-16-generic). I have attached a dump of 'lsmod' for reference. When I boot into the older kernel and do a 'lshw', it shows that "hostap" is the driver used for my card. Edit: I see the same when I boot into the newer kernel.

I truly appreciate any suggestions that anyone may have. I have never had to deal with drivers/modules before, so this is a great learning experience for me.

Optimism... \\:D/

I feel like an ***. I completely disregarded hermes0710's post, but that is the one that solved the problem.

Simply ran:

apt-get install linux-backports-modules-2.6.24-16-generic

...and the problem was fixed after a reboot. Thanks much!
