On one of my Packard Bell EasyNote LV, the wireless network stop working some minutes after boot. Only a reboot get it working again. I tried to use the 3.11 rc2 kernel, but it reintroduced the black screen of death and thus was not a very good alternative. The machine need acpi_backlight=vendor in raring to not turn off the screen completely, and this setting no longer work with v3.11.
One of the other ones have not had this problem, but it might be caused by it running an earlier raring kernel. I'm testing it again with the latest kernel version now. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1160188 Title: ATH9K wireless signal weak Status in The Linux Kernel: Fix Released Status in “linux” package in Ubuntu: Confirmed Status in “linux” package in Gentoo Linux: New Bug description: AR9485 Wireless Network Adapter has a low signal when in close range of station.
