I agree with the comments in #58. I also have a Lenovo M30-70 I installed Ubuntu 14.10. I tried lots of ideas suggested in the forums on google . The kernel updates made things worse, so I would not recommend it. I had to reinstall Ubuntu from scratch, that was not a problem for me as I have been setting my new laptop. I found that the workaround in #55 pretty effective however, the wifi connection dropped and in some cases i would not be able to reconnect until the laptop was rebooted. The connection would drop randomly sometimes after 2 hours and sometimes 10 minutes, only rebooting the system allowed it to reconnect. Then I stumbled upon a post in the Opensuse forums which mentioned that deactivating the bluetooth as a a default setting may improve the stability of the connection. It has worked for me. My recommendation would be to change the settings as suggested in #55 and if you are not bothered about bluetooth turn it off. I monitored the connection in the terminal (i used wavemon) for various solutions this gave me the best result. Without turning off bluetooth gave me a max of 2 hours of wifi connection. Whilst the connection has been stable and not dropped for 19 hours if I applied #55 and deactivating the bluetooth. I hope this might be of help.
