[Henk Stubbe <ubuntu@xxxxxxxx>]

Hello Christopher,

I have tried with vivid a few weeks ago already (live cd), but that
didn't help either. Should I retry that or is there a way to use the
latest firmware in 14.04? I don't have any spare partition on this
machine to install 15.04 on, and given that 15.x is not LTS i don't want
to overwrite my current LTS with that.

I will try the mainline kernel, although I did try that as well several
weeks ago (even tried upstream kernels directly from kernel.org). I will
report back.

Thanks.

Title:
  rtl8723be wifi unusable on lenovo ideapad y50-70

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The rtl8723be wifi adapter rarely connects to a network. When it does,
  it will be choppy (10% to 50% packet loss on a ping to the default
  gateway) and usually disconnect after a few minutes.

  Run with fwlps=0 ips=0 as options to the rtl8723be module, or testing
  https://github.com/lwfinger/rtlwifi_new/ didn't help.
