Hi Sebastian,

Yes, we found the issue, too. With the new firmware, we still encounter the issue around once a day.
We're still working on it, and will get back to you when we have any progress.

Title:
  Realtek RTL8723BE wireless card drops connection

Bug description:
  I am using Lenovo M30-70.

  I tried many workarounds from
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1320070 but no
  change, the connection is lost after a while.

  Finally I tried the rtlwifi_new driver from https://bugzilla.kernel.org/show_bug.cgi?id=83641#c1.
  I first thought it works stable but after a while it also loses the connection (see my comment there). After reconnect it works for a while again.
  I uninstalled the rtlwifi_new driver for this bug report.


  (Bluetooth does not work at all, it doesn't find any devices)
