Driver for Realtek [10ec:b723]

[hyunil227]

Hi all,

I just bought a new laptop, and installed Ubuntu. Everything works well except the Wireless network card.
Since I am new to setting up hardware drivers not provided by default, your help is very much appreciated.

lscpi -nn | grep 0280

gives me

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b723]

Any idea where / how I can install the right driver for this specific device and get elegantly connected without Ethernet cable hanging around?

Much is appreciated.

From Seoul, with Love.

Welcome to UF.

You have a relatively new chip that is not currently fully supported.

Thank you for a warm welcome.

Yes indeed the laptop is quite new and I wasn't exactly expecting everything to work out of the box.
I will try the solution in the link and post the result after.

Appreciate your help a lot.

Cheers.

Any idea what I should do to make this work?

Thanks!

Sorry to barge in, but this is what I think happened. Please check here: https://github.com/lwfinger/rtl8723be

Please notice that several files were modified 9 days ago: 'rtl8723be: Modify for API changes in kernel 3.14' You are using a 3.11-xx kernel, so it won't compile properly; 10 days ago, it did. I am trying to work out a solution.

I have emailed the author.

[hyunil227]

Ouch that hurts. Please let me know if there's any updates.

Cheers!

Checking out the earlier version by

git checkout 604aa9058fb9e5bb1cf571c99989d081f8fc8b9

has solved the problem. It's a git repository afterall.

Wow! Awesome. Glad it's working.

Just for the benefit of the searchers out there, would you please tell us in detail the process to git the older version?

Of course. Git is a Version Control System, meaning every single version of the source code can be retrieved when needed.
The checkout method described in the solution you've linked basically is a command to pull the latest code from the repository.
I just added one more line to that.

sudo apt-get install linux-headers-generic build-essential git
git clone http://github.com/lwfinger/rtl8723be
cd rtl8723be
git checkout 604aa9058fb9e5bb1cf571c99989d081f8fc8b9
make
sudo make install
sudo modprobe rtl8723be

And that's about it!

I was actually able to get the Wireless Card working, but since my laptop is very new to the market, so many of the parts inside are missing drivers.
For example, the touchpad. Therefore I guess I am kind of stuck with Windows for now, until there are drivers available for these parts.
