在Ubuntu 20.04上安装TP-link TL-WN725N USB wifi驱动

Question

我有一个 USB wifi 适配器 tp-link 型号 TL-WN725N。它工作正常，但今天突然说“找不到 wifi 适配器”。所以我尝试从此页面安装驱动程序。但安装失败。make all命令未编译，然后我再次检查了该网站。网站上写着，Operating System: Linux (kernel 2.6.18 ~ 3.19.3). 但我的内核是5.11.0-25-generic。USB 设备会找到所有可用的 wifi。但它无法连接到它们。我现在能做什么？

这是我收到的错误：

Answer 1

我们仍然无法发现为什么使用通常的内置内核驱动程序的设备无法按预期连接\xe2\x80\x99。但是，我注意到这里的驱动程序版本比内置驱动程序新。https://github.com/lwfinger/rtl8188eu

\n

让\xe2\x80\x99s 安装它，看看是否有帮助。

\n

通过以太网、网络共享或任何可能的方式建立临时互联网连接，打开终端并执行以下操作：

\n

sudo apt update\nsudo apt install git \ngit clone https://github.com/lwfinger/rtl8188eu.git\ncd rtl8188eu\nmake\nsudo make install\nsudo -i\necho \xe2\x80\x9cblacklist r8188eu\xe2\x80\x9d  >>  /etc/modprobe.d/blacklist.conf\nmodprobe -r r8188eu\nexit\n

\n

拔下并重新插入您的 USB 无线设备，并告诉我们是否有任何改进。

\n

在每次更新内核版本时，在请求重新启动后，请执行以下操作：

\n

cd rtl8188eu\nmake clean\ngit pull\nmake\nsudo make install\n

\n

请暂时保留这些说明和 rtl8188eu 目录。
