Workaround #39 solved this issue in Ubuntu (Vivid Vervet) for me a
couple of month ago.

Last week I upgraded to Ubuntu 15.10 (Wily Werewolf) and this issue returns.
Neither workaround #39 nor workaround #55 "fix" this issue for me.

Any hints?

Bug description:
  As my testing result with ThinkPad E540 and other users' report[1],
  RTL8723BE drops connection with MSI enabled, need to backport
  329d6e299f92a591acb3a80f6d597a5f9dce7e6d "rtlwifi: rtl8723be: disable
  MSI interrupts mode"

  Tips for RTL8188EE [10ec:8179] and RTL8723BE [10ec:b723] users: those
  hardware modules have MSI compatibility issue, on some certain
  platforms they work fine with MSI but break connections without MSI,
  on some other certain platforms it's opposite. You could try to toggle
  its module parameter "msi"
