I have installed Arch Linux on the maschine and observed the same behaviour of the wireless card as on Kubuntu: it was down on boot. When I tried to ifconfig wlan0 up I got an error message about rfkill:
SIOCSIFFLAGS: Operation not possible due to RF-kill and rfkill list shown the card as being blocked. So I had to issue the commands: sudo rfkill unblock wifi sudo ifconfig wlan0 up and then manually connect to my network. Then I added following line to the file /etc/modprobe.d/modprobe.conf: options ath_pci rfkill=0 and rebooted. Since then, the wireless card is up on boot time and the system clock is working ok even without any network connection. The next thing happend was that when pulling out the power cable the wireless network card would go down and the system clock would begin to slow down as well, so I changed the KDE power settings to not do anything when changing to battery power. I am not sure about the exact connection between the system clock and the wireless card being down at boot time or being turned off on battery power, but it seems that some kernel module is not detecting the card appropriately and shuts it down with the side effect of slowing down the system clock. But this is only my assumtion. Nevertheless I hope this information helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/561030 Title: System clock runs about two times slower if no connection to internet -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
