I'm downloading from archive.canonical.com/ubuntu ...but NOT from a
mirror. The test kernel as of #77  is already at version 49 !, so how
can a kernel in proposed be at version # 48.

That does seem to make any sense to me. Even if it where at version 48,
the software updater would ignore it, as there is a more recent version,
i.e. #49 , available.


uname -a yields ...Linux heri-hp-pc 4.15.0-46-generic #49 SMP Fri Mar 8 
13:21:42 CST 2019 x86_64 x86_64 x86_64 GNU/Linux, i.e. that is the test kernel, 
which I have verified and as well in use for quite a while.

So, I claim again that there is a versioning issue or the reverted
sources have not been checked in properly.

Title:
  rtl8723be wifi does not work under linux-modules-
  extra-4.15.0-33-generic

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  === SRU Justification ===
  [Impact]
  Realtek 8723be's ant_sel parameter stops working since 4.15.0-33.36.

  [Fix]
  The commit that causes the regression works in mainline, so there are
  some functional dependencies are not in 4.15.

  Finding those dependencies can be hard since I don't have the hardware
  to test with, also pulling new commits may cause new regression. So the
  safest way to deal with this bug is to simply revert the regression
  commit.

  [Test]
  User confirmed reverting the commit can fix the issue.

  [Regression Potential]
  Low. Realtek 8723be works without this commit.

  === Original Bug Report ===
  When starting Xubuntu 18.04.1 LTS on a laptop HP 1S-af023ng with kernel 
4.15.0-32.35 amd64, wifi via rtl8723be works OK.

  Using actual 4.15.0-33.36 amd64 instead, rtl8723be doesn't find any
  wifi networks and thus there is no connection. Changing the antenna
  setup in /etc/modprobe.d/rtl8723be_options.conf doesn't help either;
  as a workaround an external wifi device (Gigaset USB Adapter 108)
  works.

  The expectation is that wifi through rtl8723be will still work under 
4.15.0-33.36 as it did previously.
