The only way to get wifi working is by blacklisting ideapad_laptop. As far as i know the bug affected other models too (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1324095) but the patch released didn't works on my model. PS: i tested the live version of Ubuntu 15.04, same results: wifi still not working due to the ideapad_laptop module.
