我有一台华硕 ROG GL553V，最近我安装了 Ubuntu 16.04，带有 gnome 桌面。我的 wifi 卡出现了问题，我尝试了很多解决方案，包括这和这没有成功。

如果我运行lsmod来查看安装了哪些模块，我会得到以下信息：
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
不知道这样是否没问题，当操作系统启动时，它给了我一个错误rtlwifi-new-dkms。崩溃报告如下：
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.

答案1
因此，我最终解决了切换到 Debian 9 的问题，使用此版本我的笔记本电脑的行为很稳定。
使用 Ubuntu 16.04 时，我更新了内核，但这并没有解决任何问题。所以我决定换用 Debian。现在一切正常。
