希望你一切都好。我试图让 Ubuntu 识别我的外部无线网卡，在此过程中，我设法以某种方式禁用了 Ubuntu 读取集成无线网卡的能力……我正在使用一台 Sager 电脑，自从我第一次双启动我的原生 Windows 10 机器以来，它一直在运行（我相信）iwlwifi。我买了一个 tp-link wn722n USB WIFI 适配器，希望让它在 Ubuntu 上运行。我按照这里的步骤操作如何在 Ubuntu 14.04 上安装 TP-Link TL-WN722N 的驱动程序？尝试使用第一个回复中概述的 4 步流程使其工作。基本上，它会告诉您下载反向移植（我下载了最新版本）并配置 ath9k。但按照这些步骤操作后，我重新启动了，之后我的集成 wifi 卡和 tp-link 都无法工作。我正在运行 Ubuntu 16.04，但认为这篇文章会对我有所帮助。
我在论坛上看到过，它无法正常工作的原因可能是因为我安装了可能存在冲突的驱动程序。但是，现在我不确定是什么搞乱了我的集成连接，因为我已在 /etc/modprobe.d/blacklist.conf 中将所有这些驱动程序列入黑名单（如下所示），但它仍然无法正常工作。
blacklist ath9kblacklist ath9k_htc
blacklist ath9k_common
blacklist ath9k_hw
blacklist ath
blacklist acer-wmi

非常感谢！我很感激此时能得到的任何帮助来恢复我的集成卡！我正在考虑尝试按照此威胁的答案建议运行以下命令：Ubuntu 12.10 无线问题；仅显示蓝牙选项。如果您还有其他问题，请告诉我。很抱歉发了这么长的帖子，但我希望尽可能详尽。

首先，删除您添加的黑名单条目：
blacklist ath9kblacklist ath9k_htc
blacklist ath9k_common
blacklist ath9k_hw
blacklist ath
blacklist acer-wmi
重启。添加宏碁wmi，您的内部设备现在应该可以正常工作了。
你的 USB 是这个神秘的条目：
Bus 003 Device 007: ID 2357:010c
事实上，你的2357：010C设备不是AR9271版本，它是Realtek芯片组：https://wikidevi.com/wiki/TP-LINK_TL-WN722N_v2
我建议您使用以下方法安装驱动程序：
sudo apt-get install git dkms
cd /usr/src
sudo git clone https://github.com/lwfinger/rtl8188eu.git
sudo dkms add ./rtl8188eu
sudo dkms build 8188eu/1.0
sudo dkms install 8188eu/1.0
sudo modprobe 8188eu
您可能需要将驱动程序列入黑名单，以便内部无线上网设备以使 USB 正常工作。
您还需要删除 compat-wireless：
cd backports-3.16-1
sudo make uninstall
重启。
