Unstable Wifi Atheros AR9287 Ubuntu 10.10

Hello,

Read the following:

https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide

Regards,

Allan :)

Thanks, i've been going through the pionts in your link, but it does not seem to solve the problem. I am able to connect to the network and send/recive some information some of the time.

This is the result of runnig the comand:

sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|rt6|rt7|usb|witch|wl'; iwconfig; cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl'; sudo hwinfo --netcard ; cat /var/lib/NetworkManager/NetworkManager.state; sudo lsmod

Result:

W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/main/i18n/Translation-nb.bz2 Something wicked happened resolving 'dl.google.com:http' (-5 - No address associated with hostname)

E: Some index files failed to download, they have been ignored, or old ones used instead.

still, after trying this, my problem seems to be the same. I replaced aptitude with my package manager apt-get when i got an error first time. I'm quite lost now, do i need to change to a new driver perhaps? Does anyone need me to post any new information to this problem in order to solve it?

Thanks :)

After some time, this seems to have solved the problem. Thanks a lot for the support.

Thanks ahambidge, that solved my question.

I have an Acer 5738ZG laptop which come with an AR9287. I was experiencing exactly this bug.
I simply installed the package "linux-backports-modules-wireless-maverick-generic" and the problem was gone.

Sorry I can't remember nor find again the Internet site on which I found this solution.

Enjoy!
Eka

I forgot to mention that you have to restart the computer after package installation...
