[Bug 1493143] Re: rtl8723be wifi unusable on lenovo ideapad y50-70


Henk Stubbe, to advise, it's much easier to debug, and keep upstream's
attention, when talking about one router with easy access to specifics
(ex. Linksys), versus all the different ones that may be connected to,
and/or ones where specifics aren't available.

Despite this, with your device specifically, it has a two-parter, the
kernel, which you have tested a later version of, and the firmware,
which is the older one in Trusty.

Hence, in order to allow additional upstream developers to examine the
issue, could you please test this with the latest firmware, and latest
upstream kernel?

The latest firmware is available in Vivid+, or via

Regarding the latest mainline kernel, could you please test the latest
one available from the very top line at the top of the page from
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release
names are irrelevant for testing, and please do not test the daily
folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:

Please note, an error to install the kernel does not fit the criteria of

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

  rtl8723be wifi unusable on lenovo ideapad y50-70

Status in linux package in Ubuntu:

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
