蓝牙和 Wi-Fi 在 Ubuntu 16.04 上无法使用

蓝牙和 Wi-Fi 在 Ubuntu 16.04 上无法使用

我在一台 Ubuntu 16.04 机器上工作,我想使用我的蓝牙耳机。该卡是Realtek RTL8821CE 802.11ac PCIe 无线网络适配器,找不到合适的驱动程序来安装以使其工作。

这是输出inxi -Fxz

Network:   Card-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
           driver: r8169 v: 2.3LK-NAPI port: d000 bus-ID: 03:00.0
           IF: enp3s0 state: up speed: 1000 Mbps duplex: full mac: <filter>
           Card-2: Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter
           driver: rtl8821ce port: c000 bus-ID: 04:00.0
           IF: wlp4s0 state: down mac: <filter>

这是输出rfkill list

0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

dmesg这是我认为与所有这些都相关的输出:

我不知道如何解决这个问题,我已经尝试安装与此问题相关的新闻中建议的几个驱动程序,但都没有用。有什么建议吗?
