I think you need to open a new thread. This was a connection problem, not a weak signal problem. Keep trying, there are very capable people out there to help you.

Deavtivate the power management and the hardware encryption of the driver:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
sudo iwconfig wlan0 power off
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k

[seyavash]

i did, not much different in connectivity totally disappointed with this , anyway thanks a lot for concern

Deactivate the N-mode in your router to "b+g" only.
