I still have the original problem I reported:
Wifi works fine with original HP set up of computer but will not work
if I try to install any other Debian/Ubuntu based OS or update Ubuntu
to latest version. 
HP have obviously tweaked the installed version somehow to make it
work.
A Puppy Linux derivative worked as did Console Linux but they are the
only ones I have found so far.
My computer is an HP 455G2 with realtek RTL8723BE wifi, purchased with
Ubuntu 12.04 installed

I am here on a HP Pavilion Laptop with beatsaudio. No Model Number -
nothing.

The Wifi card is: (in Germany!)

--------------------------------------

I am now under kernel:
4.4.0-21-generic

-------------------------------------

Before I tried everything I could find to get my wifi up but I do not
even see one spot. So no connection at all. I even cloned git and
compiled the driver - which worked fine.

By the way the BT seems to be fine - although I have not checked cause
I
do not need BT.

I added the options sugested in rtl8723be.conf

options rtl8723be fwlps=0 swlps=0

But this did not help either.

In my disappointment I tried this:
>From https://bugzilla.kernel.org/show_bug.cgi?id=83641#c1

"There is a new version of this driver at GitHub. You will need to
have
the package with the kernel headers installed.

git clone http://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

This version of the driver will be submitted for inclusion in kernel
3.18. I ran it for 39 hours with no disconnects."

---------------------------------

no errors but no change.

---------------------------------

Checked this link:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1240940

---------------------------------

Then I tried several params and finally this worked somehow.

sudo modprobe -rv rtl8723be

sudo modprobe -v rtl8723be msi=1

I now was able to see wifi networks - hoorayyyy!! :)

---------------------------------------------------------

I then tried to connect to my network - but failed.

I am sitting 1 m next to my router.

Then I changed region to Germany:

echo 'KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform",
RUN+="/sbin/iw reg set DE"' | sudo tee
/etc/udev/rules.d/regulatory.rules

and then I was able to connect. My options are now:

options rtl8723be fwlps=0 swlps=0 msi=1
Now it runs perfectly! Thanks to all!!
