Eu tenho um ASUS ROG GL553V, recentemente eu instalei o Ubuntu 16.04, com o desktop gnome. Eu tive problemas com a placa wifi, e eu tentei muitas soluções que eu encontrei incluindo isso e < a href="https://forums.linuxmint.com/viewtopic.php?f=53&t=204172&hilit=Rtl8723be&start=80#p1286298"> isso sem sucesso.

EDIT 2:
Se eu executar lsmod para ver quais módulos estão instalados, recebo este:
rtl_pci 32768 1 rtl8723be
rtlwifi 77824 4 rtl_pci,btcoexist,rtl8723_common,rtl8723be
mac80211 778240 3 rtl_pci,rtlwifi,rtl8723be
cfg80211 622592 2 mac80211,rtlwifi
E não sei se está tudo bem, e quando o sistema operacional me deu um erro com rtlwifi-new-dkms . O relatório do acidente é:
mié feb 28 08:55:16 -03 2018 crash report /var/crash/rtlwifi-new-dkms.0.crash detected
/var/crash/rtlwifi-new-dkms
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
mié feb 28 08:58:21 -03 2018 crash report /var/crash/rtlwifi-new-dkms.0.crash detected
Então, finalmente resolvi o problema de mudar para o Debian 9, com esta versão meu comportamento de laptop é estável.
Com o Ubuntu 16.04 eu atualizei o kernel, mas isso não resolve nada para mim. Então eu decidi mudar para o Debian. Agora tudo funciona bem.
