https://bugzilla.kernel.org/show_bug.cgi?id=105471 is about a different
card, is about latency rather than connection drops, and is marked
solved. Do you want me to file this upstream? There are countless
reports about this card, but none upstream.

Title:
  10ec:b723 [Lenovo B5400] Realtek RTL8723BE drops connection until
  reboot

Status in linux package in Ubuntu:
  Triaged

Bug description:
  I have a Lenovo B5400 laptop with RTL8723BE wireless module. Using 802.11n 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.

  Router Manufacturer: EDIMAX
  Model: BR-6214K
  Firmware version: 1.40 2008/11/03 08:33:04

  Switching to 802.11g (54Mb/s) shows a small performance improvement
  while browsing websites. However there are still random "ping jumps"
  and the connection still drops (maybe 1-2 minutes later than usual at
  least).

  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
