![Realtek RTL8723BE 无线网卡在 Ubuntu18.04 中无法工作](https://linux22.com/image/929269/Realtek%20RTL8723BE%20%E6%97%A0%E7%BA%BF%E7%BD%91%E5%8D%A1%E5%9C%A8%20Ubuntu18.04%20%E4%B8%AD%E6%97%A0%E6%B3%95%E5%B7%A5%E4%BD%9C.png)
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。

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。
