Unstable realtek WIFI connection


I own a Lenovo model Y50 notebook with a Realtek wifi card. I run Plasma 5 DE.

I manage WIFI connection via Network Manager. The connection works pretty good for the first 5/10 minutes and then, as time goes by, it becomes unstable and I loose the connection every few minutes.

The card is a RTL8723be model, please check the link below, it is a stamp of the YaST Hardware Info:


Can you help on that and try to find some more info or log?

Thanks a lot.


I find there’s usually someone fixes realtek problems on github. Try this
My realtek’s an 8192 but github works for me.

Sorry, I think that’s a link to the wrong driver, the rtl8273bs. But if you google rtl8723be there seems to be quite a few fixes.

Thanks pete for reply. Ok I see, I’ll give a try with the following solution I found on GitHub and later on post the result:



Nope, I can’t fix it. Maybe the GitHub code fits for other distros.

Is there a way to solve this problem?


That repo is not the original, try lwfingers instead, I see that his last commit was to the bluetooth-conflict. If this doesn’t solve it you could switch off bluetooth in the bios settings, provided you aren’t depending on bluetooth.

Thanks hank_se for the reply. I downloaded the library, well I’m not very used to compiling and I feel not very comfortable with make commands.
However, in the root directory of the library I did a:


and received this error?:

**linux-q7xj:/home/matteo/tmp_matteo/rtlwifi_new #** make
make -C /lib/modules/4.1.20-11-default/build M=/home/matteo/tmp_matteo/rtlwifi_new modules

Makefile:57: set di istruzioni per l'obiettivo "all" non riuscito                             ----> ... instruction set failed

Maybe (or for sure) I’m missing something…


Probably you don’t have a complete build environment for kernel modules. Go to yast>software management and select patterns, scroll down to development and select Linux Kernel Development. Btw you don’t have to be root to build the modul, after a succesful build switch to root and run make install.


Yessss. The installation of these drivers did solve my WIFI connection, at least, till now.
Eventually, I’ll post a newer reply in case the issue will reappear.
It is stable now and moreover pages seem to load even faster, it’s my impression of course, can’t be more precise.

I can confirm you hank_se, the build environment for Linux Kernel was needed.

Here is the make install result:

**linux-q7xj:/home/matteo/tmp_matteo/rtlwifi_new #** make install
make -C /lib/modules/4.1.21-14-default/build M=/home/matteo/tmp_matteo/rtlwifi_new modules

thanks all for support, much appreciated.



the wifi connection is stable now and works pretty well.
As stated above from hank_se there is a problem with the library and bluetooth. Indeed I can’t activate it.
Is it possible to solve it? Is it possible to have both wifi and bluetooth working?

Please, let me know if I ought to open a new thread.



only to bump it

You’ll probably do better opening a new thread.
By the way, I don’t have the answer for you I’m afraid, mine both work well together.

ok, I’ll do it right now
