[Sebastian <s.plaza@xxxxxxxxxx>]

Thank you very much, this firmware is so much better!
The connection is very stable and faster, although it hangs up sometimes when changing the bandwidth. 
The dmesg says at that time:
AP (mac number) changed bandwidth, new config is 2452 MHz, width 1 (2452/0 MHz)

But after a clic on my ssid to reconnect (on the network manager) it is up again within seconds.
This happens about one time per several hours. I am using my notebook about 3-4 hours at evening so I mostly have to reconnect only one time and that within first hour (sometimes but rarely I wait for several seconds and it comes back again by itself).

But I am very happy because as I said it works generally much stable and faster.
Thank you!

Title:
  Realtek RTL8723BE wireless card drops connection

Status in HWE Next:
  New
Status in linux package in Ubuntu:
  In Progress

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)
