Re: problems with madwifi and Atheros AR5418
Oh, you're right, I guess I didn't notice that before. In any case, it doesn't appear to cause any problems for me either. It's just an annoying error message.

Re: Re: problems with madwifi and Atheros AR5418
When you run dhclient without arguments, it tries to get an ip address on any of the interfaces listed with /sbin/ifconfig minus the lo interface. If you take a look at that output with the ath9k module loaded, you'll see a "wmaster0" interface. My understanding is that this is a kind of abstraction layer from which the wlan0 interface is created. Thus, trying to get an ip address directly on it doesn't work. Of course wlan0 should get an ip just fine provided your associated to an AP with dhcp. If that message disturbs you, you could try runnning "dhclient wlan0" so that it only tries to get an address on wlan0 which is all you really want anyway.

I would suggest reporting this to the ath9k-devel list: https://lists.ath9k.org/mailman/listinfo/ath9k-devel especially if it is reproducible. Kevin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Re: problems with madwifi and Atheros AR5418
Sorry if I used the wrong notation, that was 25 Mbits/s ~ 3.2 Mbytes/s which is only slightly faster that 11g so it's not that "wow", but an improvement nonetheless. What modules is module assistant trying to build? The headers shouldn't be a problem. If you've compiled your own kernel, just make sure to keep the source tree from the compile (that means don't "make clean" it too). I did however notice a few things weren't yet bleeding edge enough for the new kernel. A common problem is that the asm/semaphore.h header is now at linux/semaphore.h. If you take a look in your source files and switch that around, things might work. For example, see this bug on tp_ctrl: http://sourceforge.net/tracker/index.php?func=detail&aid=2041469&group_id=1212&atid=101212 Kevin On Mon, Sep 8, 2008 at 9:49 AM, Manuel Pégourié-Gonnard <[EMAIL PROTECTED]> wrote: > Kevin Mitchell a écrit : >> The ath9k in 2.6.27-rc5 is working famously for me on my Thinkpad T60 >> AR5418.

Re: problems with madwifi and Atheros AR5418
The ath9k in 2.6.27-rc5 is working famously for me on my Thinkpad T60 AR5418. I'm even creeping past 11g speeds (25MB/s on a good day). Here are instructions for compiling the kernel in Debian: http://www.thinkwiki.org/wiki/How_to_install_the_development_version_of_atk9k. There is also someone on Ubuntu forums who has created a script to compile the module for pre 2.6.27 kernels and stick it in a .deb package for you. I have found this be compatible with Debian, though I haven't tried out his latest version http://ubuntuforums.org/showpost.php?p=5535562&postcount=3. I used to use madwifi and didn't experience the kind of problems you speak of. I did however notice that somewhere along the way, there was a regression that slowed down the connection by a non negligible amount http://madwifi.org/ticket/2043. You might try downloading 3401 snapshot (I think you use the "-r 3401" as an argument to svn). I had meant to pinpoint exactly when and where this regression occured, but then ath9k came out and there was an exponential decay in my caring coefficient.

Re: Re: where is ath9k?
I've been using ath9k in a 2.6.27-rc3 testing kernel and it works great! The sureest bet would be to download and compile that kernel which I've documented here: http://www.thinkwiki.org/wiki/How_to_install_the_development_version_of_atk9k. Alternatively, there is a thread in Ubuntu forums where a script has been posted to compile ath9k for older kernels and build it as a .deb package. http://ubuntuforums.org/showthread.php?t=874097 Kevin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
