Realtek RTL8723BE 无线网卡在 Ubuntu18.04 中无法工作

我有一台 HP 笔记本电脑（Hp 15R250Tu），Realtek RTL8723BE将内核升级到 5.4.0-45 通用版后，WIFI 卡。WIFI 连接在一段时间后（例如 15-20 分钟）不断断开，并显示消息激活网络连接失败然后无论我怎么想都无法连接，剩下的唯一选择就是重启。有时它根本不会在菜单中显示 Wifi 选项，只是飞行模式处于活动状态，将其切换为关闭状态，蓝牙打开，这种情况持续进行，但 WIFI 不会显示。甚至我打开笔记本电脑将天线线换到（辅助端口/2 号），令我惊讶的是没有第二个天线端口wifi 卡中根本没有给出。所以所有的天线都依赖于单个连接，这样就没有空间来交换天线端口。此外，我尝试了 Live boot，结果很奇怪，但即使是实时启动未显示无线选项我尝试了 Linux mint 和 Manjaro。这个问题持续了好几个月，尝试了 Larry finger git hub branch、Dkms 等几种解决方案，但都没有成功。

答案1

从聊天和评论中...

我们从插槽中拔出调制解调器/蓝牙卡，然后重新插入，现在调制解调器又可以正常工作了。信号很强。

用于modinfo rtl8723be | grep -i parm查看任何可用的参数设置。
