The original Atheros wifi card is extremely awful.
I agree
I think I have something that may help you.
1. Boot into Ubuntu live cd
2. Open a terminal
3. go to /sys/firmware/efivars/ or something like that
4. Make the variables writable: sudo chattr -i
5. Install ghex
6. run 'sudo ghex SCUShowHiddenPage............' (it is too long, so just push tab at the end)
7. Change the last 0 to 1
8. Reboot and you should have an Advanced Tab
9. Enter Advanced>Chipset Configuration>Bios Lock and set it to Disabled
10. Now go to Advanced>Wireless Configuration and configure that to your needs
11. Then go to Advanced>Audio Configuration and change the Audio Device Driver to Intel (that is the best option)
12. Boot up into windows and install drivers
Wifi and audio should work better until Lenovo releases an update.
I have only tested this on the latest Lenovo yoga 2 11 bios
