两天前，我的电脑上的 WiFi 停止工作了。在此之前我都没有遇到任何问题，但这次突然就发生了。
我的电脑是 2014 年的 HP Pavilion 13 x360。
我尝试了互联网上的几种解决方案，但都不起作用。有些方法暂时解决了问题，但当我休眠计算机并重新打开它时，WiFi 又无法正常工作。现在，即使我尝试了之前解决的方法，WiFi 也不起作用。
这也不起作用。
我的命令输出lspci：

似乎没有无线控制器，我不知道该怎么办。
有什么想法可以解决这个问题吗？

这是我的lshw -c network输出：

我尝试安装这个存储库：https://github.com/smlinux/rtl8723de.git
但它不起作用。我认为我应该在文件中将实际适配器列入黑名单/etc/modprobe.d/blacklist.conf，但我不知道应该在那里添加什么。
这是我的sudo ls /etc/modprobe.d/
alsa-base.conf
amd64-microcode-blacklist.conf
blacklist-ath_pci.conf
blacklist.conf
blacklist-firewire.conf
blacklist-frambuffer.conf
blacklist-mode.conf
blacklist-oss.conf
blacklist-rare-network.conf
blacklist-watchdog.conf
dkms.conf
intel-microcode-blacklist.conf
iwlwifi.conf
qemu-system-x86.conf
rtl8723be.conf
请注意，它安装的是 rtl8723be，而不是 rtl8723de
我将其添加到blacklist.conf文件中
blacklist acer_wmi
blacklist bcma/ d
blacklist brcmsmac/ d
blacklist iwlwifi
blacklist dkms
顺便说一句，我的 HP 只有单启动盘，上面只安装了 Ubuntu 18.04。
