This is not a new problem, since Ubuntu 10.04 Lucid Lynx, canonical has trouble running multiple branded wireless network cards Atheros.
As for Lucia Lynx this problem can be solved by commenting on the blacklist that is made to the Atheros driver in the configuration file
and installing the
as described in this NetStorming entry.
Unfortunately, this solution does not apply to Ubuntu 10.10 Maverick Meerkat, Since applying this solution only leads to the complete disappearance of the WiFi Network and if you keep insisting you will run out of system as it happened to me. 😀
But hey, I already have the solution to this annoying problem and in my case it is specifically for Ubuntu 10.10 Maverick Meerkat with Kernel 2.6.35-24-generic, WiFi Atheros AR928X on a laptop Acer Aspire 4540.
Note: it will probably work for you on another computer as well if the problem is continuous disconnection of WiFi with loss of performance on the computer when trying to reconnect.
What we need to do to fix this annoying problem is simply edit the configuration file
. To do this, run the following line on the terminal:
sudo gedit /etc/NetworkManager/nm-system-settings.conf
Now I actually have a text file similar to the one I show below:
# This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default. To override, specify: '--config file' # during NM startup. This can be done by appending to DAEMON_OPTS in # the file: # # /etc/default/NetworkManager # [main] plugins=ifupdown,keyfile [ifupdown] managed=false
In this file, we will change the line
. Then we will save and close the file.
With just this small modification, your WiFi will work again as if nothing had ever happened, now you just have to restart your machine and that’s it.
On x64 systems it is possible to solve this problem by running the following line on the terminal:
sudo rfkill enable all
Unfortunately, these solutions do not seem to be permanent in many cases, so we can move on to more drastic solutions, such as installing the driver package for Atheros madwifi devices.
