我怎样才能让MEDIATEK .设备7961开始工作？

Question

我从Ubuntu 20.04开始

我无法安装无线网卡驱动程序(用于Wifi和蓝牙)。

sudo lshw -C network

输出：

我安装了Ubuntu21.04，并将内核升级到5.12。我安装了网络驱动程序，我已经让wifi工作了一些(随机的，有时工作，有时不工作)，但蓝牙仍然不能工作。

我试图在这篇文章之后安装5.15版本的内核，但是在下载完内核并运行命令sudo dpkg -i *.deb之后，会得到以下错误：

我怎样才能让这个无线网卡正常工作？

Answer 1

似乎无法让内核5.15工作，所以我不得不改为5.14

通过禁用安全引导并切换到内核5.14.9来解决问题

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline

打开主线，然后选择5.14.9。单击安装。然后重新启动并引导到引导管理器，并禁用安全引导。
