I have the same issue: very low connectivity or even none. Asus UX21 with 13.04 64bits.
I do not try compat-drivers yet. ** Description changed: AR9485 Wireless Network Adapter has a low signal when in close range of station. - I disabled hardware encryption with putting: - options ath9k nohwcrypt=1 + I disabled hardware encryption with putting: + options ath9k nohwcrypt=1 in - /etc/modprobe.d/ath9k.conf + /etc/modprobe.d/ath9k.conf That doesn't seemed to help. The signal has 2 bars while it has full strength in windows. (I am 2 meters away from the wifi station) s400ca:~$ rfkill list all 2: asus-wlan: Wireless LAN - Soft blocked: no - Hard blocked: no + Soft blocked: no + Hard blocked: no 3: asus-bluetooth: Bluetooth - Soft blocked: no - Hard blocked: no + Soft blocked: no + Hard blocked: no 4: hci0: Bluetooth - Soft blocked: no - Hard blocked: no + Soft blocked: no + Hard blocked: no 5: phy0: Wireless LAN - Soft blocked: no - Hard blocked: no + Soft blocked: no + Hard blocked: no ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: linux-image-3.5.0-26-generic 3.5.0-26.42 ProcVersionSignature: Ubuntu 3.5.0-26.42-generic 3.5.7.6 Uname: Linux 3.5.0-26-generic x86_64 ApportVersion: 2.6.1-0ubuntu10 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: jintux 1988 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: jintux 1988 F.... pulseaudio Date: Tue Mar 26 06:33:06 2013 InstallationDate: Installed on 2013-03-25 (0 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MachineType: ASUSTeK COMPUTER INC.
