rtl8812au (Edimax EW-7822UAC)

我有 rtl8812au (v4.3.14) 和 rtl8814au (v4.3.21) USB 无线网络适配器的 github dkms 内核驱动程序,它们在 17.04 中运行良好,但在升级到 17.10 时无法构建。这两个驱动程序都基于类似的代码,并且无法以类似的方式构建。

我不知道是新的 gcc 编译器还是新的 4.13 内核导致了这个问题。可能只需要对它进行一些小的调整就可以Makefile解决错误。

如果我使用标准make命令而不是正常dkms add/build/install序列,我可以很容易地看到错误。

以下是 rtl8812au 代码版本 4.3.14 的错误(比当前 Ubuntu 存储库中的版本更新)...

所引用的代码osdep_service.h如下所示...

#ifdef PLATFORM_LINUX
    #if (LINUX_VERSION_CODE < KERNEL_VERSION(3, 8, 0))
    daemonize("%s", name);
    #endif
    allow_signal(SIGTERM);
#endif
#ifdef PLATFORM_FREEBSD
    printf("%s", "RTKTHREAD_enter");
#endif
}

__inline static void flush_signals_thread(void) 
{
#ifdef PLATFORM_LINUX
    if (signal_pending (current)) 
    {
        flush_signals(current);
    }
#endif

rtl8814au 的错误和代码看起来很相似,所以除非被请求/要求,否则我不会发布它们。

请帮忙。我想让我的无线网络恢复在线。

答案1

您可以尝试:

git clone https://github.com/zebulon2/rtl8814au.git
cd rtl8814au
make
sudo make install
sudo modprobe 8814au

它在我的 17.10 系统上完美运行。我不确定是否可以推荐 dkms 进程,因此内核更新需要重新编译。

答案2

感谢@chili555 为我指明了正确的方向。链接中提到的 rtl8814au 驱动程序git clone适用于 17.10,而同一作者还有一个可以运行的 rtl8812au 驱动程序,也适用于 17.10。

从记忆里...

rtl8812au (Edimax EW-7822UAC)

sudo git clone https://github.com/zebulon2/rtl8812au-driver-5.2.9.git
note: dkms.conf file already included
sudo cp -r rtl8812au-driver-5.2.9 /usr/src/rtl8812au-5.2.9
sudo dkms add rtl8812au/5.2.9
sudo dkms build rtl8812au/5.2.9
sudo dkms install rtl8812au/5.2.9
dkms status

rtl8814au(Edimax EW-7833UAC 和 D-Link DWA-192)

sudo git clone https://github.com/zebulon2/rtl8814au.git

create dkms.conf and add these lines...
