我有一个 USB wifi 适配器 tp-link 型号 TL-WN725N。它工作正常，但今天突然显示“未找到 wifi 适配器”。所以我尝试从这页面。但安装失败。make all命令没有编译，然后我再次检查了网站。网站上说，Operating System: Linux (kernel 2.6.18 ~ 3.19.3)。但我的内核是5.11.0-25-generic。并且 USB 设备找到了所有可用的 wifi。但它无法连接到它们。我现在该怎么办？
这是我收到的错误：
$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;

答案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。不过，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的互联网连接，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善。
每次更新内核版本时，按要求重新启动后，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 rtl8188eu 目录。
