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
- 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
sudo nano /etc/modprobe.d/ath9k.conf
Did that help you out? If so, let us know in the comments!
