我刚刚将我的安全启动前、UEFI* 东芝2012 卫星 P755-S5390笔记本电脑从 15.10 更新到 16.04。在 15.10 中,无线适配器工作正常。现在,Ubuntu 拒绝承认我的笔记本电脑有无线接口。我已经重新启动了很多次,完成了以下操作:
apt install flashrom librtlsdr* nictools* r8168-dkms rtl-sdr rtl8812*
这似乎是成功的,而我在网上找到的许多其他东西都无济于事。的Additional Drivers

*我的笔记本电脑从来没有 UEFI,仍然只有 BIOS;因此,我的问题与Realtek 驱动程序 RTL8723BE not working in Ubuntu 16.04 (kernel 4.4) 不同。
我不知道你是否已经看过这篇文章,但这里有。关联
根据该问题的答案,似乎有更好的驱动程序可供第三方开发人员在 GitHub 中维护。
因此,打开一个终端 (Ctrl+Alt+T) 并按照以下步骤操作:
希望这可以帮助 :)
因此,如果您没有驱动程序,那么从源代码安装驱动程序的另一个答案绝对是正确的。
就我而言,我所要做的就是
*是的,这可能是一个错误。希望这可以帮助那里的另一位 Satellite P755 所有者。
