Default Bug#485034: linux-image-2.6.25-2-686: ath5k associates but no network

Package: linux-image-2.6.25-2-686
Version: 2.6.25-4
Severity: normal

I just installed linux-image-2.6.25-2-686 to try and take advantage of
the new ath5k driver. My /etc/network/interfaces file says:

auto ath0
iface ath0 inet static
wireless_essid <ESSID>
wireless_key <KEY>
address <ADDRESS>
netmask <MASK>
gateway <GW>

When I say "ifup ath0", iwconfig reveals that ath0 is associated to my
AP, ifconfig looks right (as it should with a static config). dmesg
looks great too:

ath5k_pci 0000:02:02.0: registered as 'phy0'

ath0: switched to long barker preamble (BSSID=02:1e:58:07:5d:f2)

However, I can't ping my access point.

At this point I'm not sure if the source of this problem is a bug, an
immature driver, or a lack of magic dust in my /etc/network/interfaces
file. Please advise.

can you please try out 2.6.26-rc8, see trunk apt lines
http://wiki.debian.org/DebianKernel

it should have newer ath5k driver.
also trying an dhcp setup would be cool.

thanks

Will do, as soon as it creeps into sid.

No, DHCP didn't help. However, on the ath5k-users mailing list, Pavel
suggested that it might be a WEP issue with my wireless card (AR5211),
and it was. When I turned off WEP, I got a good network connection with
both a static configuration and with DHCP.

I'm thinking that using WPA would be a good workaround for this bug, and
would be slightly more secure besides. I haven't had the time to try
yet, but I did find [1]. Does this look up to date?

1. http://wiki.debian.org/Manual-Howto#head-6fdd87d329e68a583e5fde32c6b21e460e5541a5

Unless someone else chimes in to the contrary, it appears that this bug
could be relabeled as:

linux-image-2.6.25-2-686: ath5k associates but no network with WEP and
AR5211

I'll report back when I've tried 2.6.26 or WPA.

In the meantime, I use SSL/SSH for all of my communications, and limit
the MAC addresses that can connect to my AP, so I'm comfortable without
WEP for the moment. The good news is that the ath5k driver is otherwise
rock solid and is worth using. My network connections have been up for
over a week!

Thanks, maks!

Since Lenny now contains images based on 2.6.26, did you have a chance to
test them already?

Cheers,
Moritz

Sorry I didn't reply sooner--I was holding out to try WPA but haven't
had the time.

I did, however, try WEP with 2.6.26. My box still did not associate.
