Atheros AR9485 / Gateway NE56R34u

**nbokowy** · December 8th, 2013

Hello everyone. This is my first post so if I screwed something up, sorry 8)

I recently purchased a Gateway NE56R34u for my brother. I put Ubuntu 12.04 on it and sometimes after I put in my wireless password it will attempt to connect but never actually make the connection. This will go on for a few minutes or longer. Eventually if I wait long enough it will connect. Then it usually stays connected for a long while. But this is very annoying.

I don't know much about computers but I can follow detailed directions. Based on from what i've been reading I think you will need the below information from me.

Code:
iwconfig
lo no wireless extensions.

Any help would be greatly appreciated! 8)

Thanks

Deactivate the hardware encryption of the driver via:

Code:

echo "options ath9k nohwcrypt=1" | sudo tee -a /etc/modprobe.d/ath9k.conf
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k

Thank you very much! This seems to have fixed my brother's computer. I also have the same computer as his and was wondering if I would have to do the same commands to fix mine? My info is below. Sorry for the noob questions 8)

Try a driver update:

Code:

sudo apt-get install --reinstall build-essential linux-headers-$(uname -r)
wget media.cdn.ubuntu-de.org/forum/attachments/39/19/5443987-rtl_92ce_92se_92de_8723ae_88ee_0012.0207.2013.tar.gz
tar xvf 5443987-rtl_92ce_92se_92de_8723ae_88ee_0012.0207.2013.tar.gz
cd rtl_92ce_92se_92de_8723ae_88ee_linux_mac80211_0012.0207.2013/
make
sudo make install
sudo depmod -a
sudo update-initramfs -u
sudo cp -r firmware/* /lib/firmware

Reboot.
