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.?
Post 16 in: http://ubuntuforums.org/showthread.php?t=2243978

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.?

Have a look at this link , if you haven t looked at it already ; https://unix.stackexchange.com/questions...untu-14-04

Hi altman,

Thanks... Yes I have seen that one... It was another confusing one...

Where it said 3.16 by it'self did not fix the problem, and the latest drivers also needed to be installed,
That's where I got lost, the link to the drivers appear to be a bunch of source code and things, so I had no idea what to do..??

That's when I found that a live Ubuntu(14.10) boot with it's 3.16 worked,
so that appeared to have the correct drivers included.

LL 3.16 kernel WiFi works...
But I get the video tearing/ripping issue

One step forward... One step back.

Hi misko,

Thanks...
I will add to my list of options, I'm going to do a new install first.
I have lost track of everything I've done to try and fix the WiFi and the Xfce/HDMI issue.
