Wireless Frequently Disconnecting Lenovo Ideapad Y560 (Atheros AR9285)

I've been running Ubuntu on my Lenovo Ideapad Y560 for a while now, but ever since I upgraded it to Xubuntu 13.10 the wireless has been frequently disconnecting on me.

The Lenovo Y560 uses and Atheros AR9285 wireless adapter, and apparently other users have had the same problem in previous versions of Ubuntu. Well I found a fix! Here's what you do:

• Create a file called /etc/modprobe.d/ath9k.conf

sudo nano /etc/modprobe.d/ath9k.conf


• Add the following line:
  
  options ath9k nohwcrypt=1
  
• Disable IPv6 by running the following in the terminal:
  
  echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf

After that reboot, and you'll find that your wireless stops disconnecting... Well, at least mine did.

Did that help you out? If so, let us know in the comments!
