    Default Unstable realtek WIFI connection

    Hello,

    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:

    http://paste.opensuse.org/31177042

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

    Thanks a lot.

    Matteo

    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?

    Thanks

    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:

    make

    and received this error?:

    Code:
    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
    make[1]: *** /lib/modules/4.1.20-11-default/build: File o directory non esistente.  Arresto.  ----> No such file or directory
    Makefile:57: set di istruzioni per l'obiettivo "all" non riuscito                             ----> ... instruction set failed
    make: *** [all] Errore 2
    
    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.

    Hi,

    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:

    Code:
    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
    make[1]: ingresso nella directory "/usr/src/linux-4.1.21-14-obj/x86_64/default"
      Building modules, stage 2.
      MODPOST 14 modules
    make[1]: uscita dalla directory "/usr/src/linux-4.1.21-14-obj/x86_64/default"
    Making backups
    Install rtlwifi SUCCESS
    
    thanks all for support, much appreciated.

    Matteo

    Hello,

    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.

    Thanks

    Matteo
