我有一个 usb wifi LB-Link WN155A，我尝试了很多方法但仍然无法工作。

我有两个无线接口，一个是 PC，另一个是 USB wifi。PC wifi 接口工作正常，但我无法让 USB wifi 工作。

对于该模块，我也尝试编译mt和rtl ko，但失败了。

我尝试下载驱动程序（8192cu 和 8188eu）

在我建立模块后，我尝试使用modprobe，但它显示

modprobe: FATAL: Module 8188eu.ko not found in directory /lib/modules/4.15.0-36-generic

我也尝试修改/etc/network/interface。但仍然失败。

编译mt7601错误

/declanlc-driver-mt7601usta/src/os/linux/../../os/linux/rt_linux.c:120:3: error: implicit declaration of function ‘init_timer’ [-Werror=implicit-function-declaration]
   init_timer(pTimer);
   ^

   pTimer->data = (unsigned long)data;

答案1

所有安装均需 sudo apt install -y git build-essential make autoconf libtool gcc gettext linux-headers-$(uname -r)

现在你可以尝试安装你的驱动程序

但在此之前我建议尝试安装

mt7601 驱动程序 git clone https://github.com/declanlc/declanlc-driver-mt7601usta.git cd declanlc-driver-mt7601usta/src make mkdir -p /etc/Wireless/RT2870STA/ cp RT2870STA.dat /etc/Wireless/RT2870STA/ insmod os/linux/mt7601Usta.ko

如果这不起作用那么尝试您提到的驱动程序

rtl8188eu： git clone https://github.com/lwfinger/rtl8188eu.git cd rtl8188eu make all sudo make install sudo modprobe rtl8188eu or 8188eu

rtl8192cu： git clone https://github.com/lwfinger/rtl8192cu cd rtl8192cu make sudo make install sudo modprobe rtl8192cu or 8192cu
