Public bug reported:
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.
