Bug Description
Binary package hint: acpi
Hi. My wireless connection works very well with Windows 7 on this Acer laptop. On Ubuntu, i was experiencing some problems (unstable connection). Some web pages were very difficult to load on Ubuntu 10.4, so I upgraded to 10.10. It seemed to be working fine, but it was because the laptop was powered by wall power and not by battery. When I disconnect AC power, my connection becomes unstable again.
My Network controller is: " Atheros Communications Inc. AR9287 Wireless Network Adapter (PCI-Express) (rev 01)".
The Kernel is: 2.6.35-26-generic
To be more precise: Network manager always displays my connection as working, but when my laptop is battery powered, some sites are very slow or unreachable (connection is timed out).
I can add the result of lsmod | grep ath, someone says there could be a module conflict:
lsmod |grep ath
ath9k 111737 0
mac80211 278659 1 ath9k
ath9k_common 3151 1 ath9k
ath9k_hw 288136 2 ath9k,ath9k_common
ath 17109 2 ath9k,ath9k_hw
cfg80211 166442 3 ath9k,mac80211,ath
Please help me! Thank you in advance.

I've shifted to OpenSUSE and with OpenSUSE my wireless connection works fine, with or without wall power. Maybe this could help you to understand the reasons of the malfunctioning, by confronting the acpi settings in Ubuntu and those used in OpenSUSE. Please, work on it if you can, because OpenSUSE is good, but Ubuntu is better :)
