I did a fresh install of Intrepid today and my wireless seems to work
very well out of the box. Since I originally reported this I'll mark it
as fixed; if it isn't for others it might be a different issue.

For me the new ath5k works much better, however every couple of hours of
use I get kicked off the network and have to rmmod ath5k, modprobe
ath5k, and restart networking to get it back. I don't know where this
might log a bug for tracking. The WiFi Signal Strength Meter Plasmoid
is consistently
Hi Guys,
Care to try installing the linux-backports-modules-intrepid package as
it recently pulled in an updated version of the compat-wireless stack
and ath5k driver.

The ath5k in backports-modules worked much better than the one we have
in the current ubuntu kernel but I think the new compat-wireless stack
is making trouble. I had the same backtraces in my dmesg as they were
mentioned in https://bugs.launchpad.net/ubuntu/+source/linux-restricted-
To blacklist ath5k, at this line to /etc/modprobe.d/blacklist:

Experiencing similar poor networking performance and periodic short-
duration freezes with an AR5212 on Intrepid. Mike mentioned building
madwifi from svn and blacklisting ath5k. As I understand it, madwifi
should still be installed with Intrepid. How do I tell Ubuntu to use
the madwifi driver
I'm getting the same issue on a fresh install of Intrepid Beta, fully
updated.
Connection keeps dropping, passwords are asked each time and performance
of the network is quite bad. lspci shows:

Thanks coubi64, I will Confirm thanks to your input.
As an update for Leann, after more use with the madwifi it is an
improvement but still a definite regression from Hardy. It is slower and
doesn't seem to get as strong of a connection; I have had to reboot into
my Hardy install to connect to
Same problem for me, logs in a post here: http://forum.ubuntu-

I'm surprised by a thing too: lspci give Atheros Communications Inc.
AR5212/AR5213 but dmesg gives ath5k phy0: Atheros AR2413 chip. Is it
normal?

Okay, after a second restart ath5k was functional again (though with the
same problems as above). I then installed madwifi from svn snapshot and
blacklisted ath5k, and my wireless experience is much better! Much
faster speeds, no CPU spikes, et cetera. However this bug is probably
still good to
After updating today (the first time I updated in about a week) and
restarting, network-manager doesn't show any wireless networks at all
(and there are usually about 4-6 here). How interesting. I will try the
madwifi PPA later tonight.

Thanks Leann. I don't see an Intrepid option for that PPA, can I just
change Hardy to Intrepid in the sources entry and have it work? I would
expect to see Intrepid listed in the drop-down and in the series below,
if it was built for Intrepid. Let me know and I can test the madwifi
PPA.
