ideapad_laptop module disable wifi on Lenovo G50-30 (rtl8723be)

[Gianluca Cavalli]

Description: Ubuntu 14.04.2 LTS
Release: 14.04
 The ideapad-Laptop module just breaks the wifi on my Lenovo G50-30 (Realtek network card: rtl8723be). 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.

A friend suggested me to follow this instructions. It worked:
1- download http://iseborn.eu/downloads/ubuntu_yoga_2_wifi/Makefile
2- download http://iseborn.eu/downloads/ubuntu_yoga_2_wifi/ideapad-laptop.c
4- open ideapad-laptop.c and change this line
DMI_MATCH(DMI_PRODUCT_VERSION, "Lenovo Yoga 2"),
in
DMI_MATCH(DMI_PRODUCT_VERSION, "Lenovo G50-30"),

3- go with a terminal where you downloaded the files and type "make" and then "make install"

note: remove any previously workaround you did before (like the blacklisting one).

So is there a way to include a patch for this models too?
