Madwifi installation for Atheros card in Karmic koala

[bigfootnmd]

Greetings all,

I have an Acer Aspire one A0751 that has the Atheros 5001 (or so) network chip. I followed drpjkurian's posted instructions to the letter. I am using Ubuntu 10.04. No kernel updates have occurred since I loaded the pci drivers two nights ago.

I am using WPA encryption. My Netbook wifi connects about 20% of the time when the netbook is in the same room as my router. I have not yet tried the instructions in the posting
https://help.ubuntu.com/community/Wi...Driver/Atheros
because I don't want to make things worse.

Any help or suggestions will be appreciated.
Oh, and of course my compliments to Dr. Kurian for his well written instructions.

I went back to Jaunty Jackalope. No further problems. In fact, connectivity better for wireless than on my desktop running Lucid.

Best,
Simon

Something that happens 20% of the time suggests a signal strength or hardware problem. If it's software, then I'd expect either 0% or 100%.

Those instructions are very unlikely to make things worse, even if they don't make things better. Dr. Kurian himself looked at them and thought they were just fine.

Minor update here. Set my Verizon supplied Actiontec router to use channel 8. So, far my netbook is connecting via wifi.

I will monitor events over the next few days before trying anything else.

This morning when I booted up my Netbook (with Lucid, and the madwifi drivers installed) my Netbook could not connect to my router. My Netbook was no more than 18 inches from my router. So, there could not have been an issue with signal strength. I also verified that my WPA key was correct in my settings for my WIFI connection. So, I did some more research and I found this community doc (which I believe has been mentioned several times in this thread.

https://help.ubuntu.com/community/Wi...Driver/Atheros

This doc was last updated on May 15, 2010. It has Dr. Kurian's excellent instructions toward the bottom of the page. There is one additonal warning about kernels 2.6.32.22 and later that I have not seen (and maybe I missed it) in this thread.

"Additional step for kernel 2.6.32.22 and later

Kernel 2.6.32.22 changed the default for the rfkill parameter of ath_pci from 0 to 1, which had the effect of killing the methods described above. You'll need to make sure that it's set back to 0 on system startup. To do that, edit (or create) the file /etc/modprobe.d/options.conf to include the line

options ath_pci rfkill=0"

Since I added 'options ath_pci rkill=0' to my /etc/modprobe.d/options.conf file my netbook is connecting 100% of the time to my WIFI router.

I have taken the last three steps from Dr. Kurian's method and placed them in a document on my Netbook desktop so that when I get kernel update in the future it will be easy to restore the madwifi drivers.
My thanks again to Dr. Kurian and to everyone who has shared their experiences with the Atheros drivers in this thread.

Still not working...
AR9287 + ubuntu 2.6.32-24-generic, (also,HP 6930P integrated an Intel 5300 card, and it works well with some other driver);

I have tried many methods, including above.
After building, lsmod | grep ath can return "ath_pci","ath_wlan",and "ath_hal", nevertheless, lshw -C network always returns "Unclaimed"...

I checked "Hard Drivers", and nothing except ATI graphic, even my intel card isn't in the list (but it works well)

Is there someone earnest to help me?
Thanks.

UPDATE:

Earlier this week I had a brain freeze and I could not remember the password to my Router. So, I reset the router to factory defaults. Immediately my Acer Aspire one A0751h using the Madwifi drivers for the Atheros 5XXX card could not connect via WIFI.
I logged in to my router and checked the WIFI settings. I had of course changed the SSID and WPA password to match what I had been using before (these were wiped when I reset the router). The channel selection was set to automatic. I changed this to channel 6 and immediately my Netbook was able to connect. So, If you have tried the MADWIFI drivers before and still have issues, change the WIFI channel on your router to 6 or 11.

Thank you very much for your compliments

I have installed the latest version of maverick, I also used the latest update from

https://help.ubuntu.com/community/Wi...Driver/Atheros

so i supposedly have two wifi networks one is wifi0 and one is ath0, the problem is atheros is not set as ath0 but as wifi0, so how can i circumvent the problem that it becomes ath0. Yes I did try to change the setting in wicd from ath0 to wifi0 as well I restarted it, I also pressed on the slider for the wifi (altho we all know the lights aren't working), so pretty much i tried everything, I even reinstalled maverick from scratch, as my operating system has a partition so no personal files get deleted!

so the problem is I still can not connect to anything without wired connection. And no wireless network shows up! The wireless was working perfectly in lucid, however you just want to know how the newest netbook edition is

[chandru1]

oh after doing what kurian has said, i have not made my wireless active. What has happened is this.

Madwifi has installed and the iwconfig command shows this.


lo no wireless extensions.

eth0 no wireless extensions.

wifi0 no wireless extensions.

Before installing madwifi i had tried these things which i posted on http://askubuntu.com/questions/18723...ss-not-working

Now if i want to remove madwifi driver how can i do it? I would be glad if anyone can make my wirless to work as i am in great need of it
