New Install LL 2.2 > NO WiFi with "rtl8723be" Chipset

[Wirezfree]

Hi,

A new install of LL 2.2, all appeared to be O.K, System info at the end.
I have to admit, I didn't check WiFi with a Live Boot. (naughty boy )
I always do the installs connected via cable.

After install & Updates I found I did not have WiFi. It is based on Realtek "rtl8723be"
Long story short after lot's of Googling, it appears lots of people have issue with this chipset.

I found a solution that appeared to work, but after 2/3 hours lost the WiFi until I did a re-boot.
Then
I found lots of reference to it being fixed in Kernel 3.16.
So I tried kernel 3.16, the WiFi appeared to work, but I then had a video ripping/tearing issue.

I tried 3.17, WiFi O.K but still had a video ripping/tearing issue.
I tried 3.18, NO WiFi, and also had a video ripping/tearing issue.

I have found possibly another option, but don't fully understand "back-ports"??
I found a thread on what, If I understand it, is installing the the latest drivers used in 3.16, but on to 3.13.?

Please install the kernel headers and build-essential beforehand -

Code:

sudo apt-get install linux-headers-generic build-essential

Then follow these steps to download and install the backported driver -
1) Download the "backports-3.16.2-1" package from here : http://drvbp1.linux-foundation.org/~...tml/backports/
2) Copy the downloaded archive to your Desktop > Right-Click > Extract here.
3) Open a terminal (Ctrl-Alt-T) and run these commands to build and install the driver -

Code:

cd Desktop/backports-3.16.2-1
make defconfig-rtlwifi
make
sudo make install

I would be taking a stab in the dark with this, and it may break my install possibly.? Comments welcome.?

So in summary, In the absence of any other ideas.?
I try the above, fingers crossed, or I'm stuck with LL 2.2 / kernel 3.13 and cable, or the "flaky" option.

Hope this all makes sense.?
