Make wireless work with Ultrabooks with ath9k+bluetooth

Postby mickey999inbox on Fri Jun 08, 2012 1:38 pm

Might be useful for those Linux Mint 13 users that bought an Ultrabook (Asus, Toshiba, Dell, etc)
These ultrabooks ( most of them ) will come with this ATH9K + bluetooth wifi netcard.
Under Linux Mint 13 (Mate at least !) your wifi card will connect to your wireless router but the speed will be outrageous low ( 52K ...maybe!)
All you have to do is the following:
1. sudo su -
2. create a file name ath9k.conf under /etc/modprobe.d (touch /etc/modprobe.d/ath9k.conf - for example )
3. nano /etc/modprobe.d/ath9k.conf and introduce one line containing the following:

options ath9k nohwcrypt=1

4.Save the file
5.Issue the following commands to remove then reload the modules properly without rebooting your system:

rmmod ath9k
modprobe -b ath9k

Now you should have the proper Internet speed .

As for the bluetooth ( if you have a bluetooth headset you'd like to use with your Ultrabook ) you will need to use Synaptics and install Bluez manager with some more extra libraries in order to be able to connect your bluetooth headset to your Ultrabook

Thanks. I've been looking for hours for a solution for my ASUS U36JC. This is perfect.

Thanks for the post. I've been having an issue with Dell Inspiron wifi on Mint 15 Olivia. I could see multiple wireless connections, but could connect to none. Whether the network used WEP, WPA or no security made no difference.

I am using an Atheros card and the ath9k driver. After reading your post and replies, I found the /etc/modprobe.d/ath9k.conf file missing. Adding it as specified corrected the issue. Thanks for the help.
