Title:
rtl8723be wifi unusable on lenovo ideapad y50-70
Status in linux package in Ubuntu:
Incomplete
Bug description:
I obtained a lenovo y50-70 a few weeks ago, and installed ubuntu
14.04.3 LTS on it (dual boot with windows 8 that came pre-installed).
$ lsb_release -rd
Description: Ubuntu 14.04.3 LTS
Release: 14.04
I have not been able to get the rtl8723be wifi adapter to work yet.
If it will connect to a wifi network at all (which is rare), it will
be choppy (10% to 50% packet loss on a ping to the default gateway)
and usually disconnect after a few minutes.
The internet suggests a few work-arounds:
- run with fwlps=0 ips=0 as options to the rtl8723be module (eg.
http://askubuntu.com/questions/590414/wifi-problems-with-rtl8723be-in-ubuntu-14-04)
- install an alternative driver (eg.

However, none of those suggested worked for me.
I have tried downgrading the kernel down to 3.13.0-62, and various
kernels in between, but none of that helped either.
