Atheros wireless not working

Question

I have been struggling hard since i have installed Ubuntu 10.10 but it has been difficult for me to get my wifi working.

So here is what i tried.

• First i checked whether i have the driver using the ifconfig command and it shows the wireless lan driver as wlan0.

• Next, i tried the command iwlist wlan0 scanning by becoming the root which gave me the output as no scan results.

• Next, i visited this link https://help.ubuntu.com/community/WifiDocs/Driver/Atheros to see as to what problem my laptop may have. I do own have an ath5k chipset. And as i followed the instructions in the above link in one of the blacklist-ath_pci.conf file had this written in it.

For some Atheros 5K RF MACs, the madwifi driver loads buts fails to correctly initialize the hardware, leaving it in a state from which ath5k cannot recover. To prevent this condition, stop madwifi from loading by default. Use Jockey to select one driver or the other. (Ubuntu: #315056, #323830

I am not that good at Linux but i have given it a try. I am desperate to have my wifi working and i would be glad if this community could help.

• ADDED: If anyone would like to know as to what drivers i am using this is the output.

Solution

I had the same problem. Almost took me a month to set it straight. Mine is an ATHEROS AR5007EG.

First I tried ndisgtk (NDISWRAPPER), ... it worked but was very fuzzy. It used to show all available Wireless networks but connecting to it took a lot of time.

Growing tired of waiting I gave mad wifi a try. It worked ... the only downside was that it needs reinstallation for each kernel upgrade.

Here are the steps:

1. First and the most important bit is undoing all that you have done so far ... specially all blacklists you have added.

2. Uninstall the mad wifi drivers already installed .. follow this link under the header "Removing old modules".

3. Once all modules are removed use this link to follow Dr. P.J. Kurian's method listed under the heading "Method Using madwifi and ath_pci" ... follow all the steps mentioned.

That should do it :)

The secret is being patient.

Hope this helps.
