["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Paweł Kowalik, just to clarify, if you have to use WORKAROUNDs like
fwlps/ips=0, then the root problem of having to adjust those parameters
wouldn't be considered solved.

Also, regarding filing reports upstream, it's not considered an upstream
issue unless you have tested the latest mainline kernel (not default
Ubuntu kernel).

Hence, could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test 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 bug 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:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

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

Thank you for your understanding.

Title:
  Realtek RTL8723BE drops connection until reboot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a Lenovo B5400 laptop with RTL8723BE wireless module. The internet connection constantly getting lost after a random duration (usually after 20-30 minutes). The NetworkManager applet does not recognize it (still looks like i have a connection), but when I try do disconnect and connect again, there is only one useful information I can find in dmesg:
  "wlan0: deauthenticating from [ap mac address] by local choice (Reason: 3=DEAUTH_LEAVING)"
  Reinserting the driver (modprobe -r rtl8723be and modprobe rtl8723) used to be my only workaround, but it does not work anymore and now I have to reboot.

  The following improves performance, but I am still encountering some minor performance issues while playing online games (random lag spikes):
  sudo nano /etc/modprobe.d/rtl8723be.conf
  options rtl8723be ips=0 fwlps=0
