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

772

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命令没有编译然后我再次检查了网站。在网站上它说，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？

这是我得到的错误：

$HOME/Documents/Driver/include/osdep_service_linux.h:261:8: error: ‘_timer’ {aka ‘struct timer_list’} has no member named ‘data’
  261 |  ptimer->data = (unsigned long)cntx;
      |        ^~
$HOME/Documents/Driver/include/osdep_service_linux.h:262:2: error: implicit declaration of function ‘init_timer’; did you mean ‘_init_timer’? [-Werror=implicit-function-declaration]
  262 |  init_timer(ptimer);
      |  ^~~~~~~~~~
      |  _init_timer

其他一些有用的命令输出：

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没有按预期连接。但是，我注意到这里的驱动程序版本比内置驱动程序更新。https://github.com/lwfinger/rtl8188eu

让我们安装它，看看它是否有帮助。

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：

sudo apt update
sudo apt install git 
git clone https://github.com/lwfinger/rtl8188eu.git
cd rtl8188eu
make
sudo make install
sudo -i
echo “blacklist r8188eu”  >>  /etc/modprobe.d/blacklist.conf
modprobe -r r8188eu
exit

移除并重新插入您的 USB 无线，并告诉我们是否有任何改进。

在每次更新的内核版本更新时，请求重启后，请执行以下操作：

cd rtl8188eu
make clean
git pull
make
sudo make install

请保留这些说明和当时的 rtl8188eu 目录。
