【问题描述】:
我正在使用 Ubuntu 16.04 机器,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安装以使其工作。
这是inxi -Fxz的输出:
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rfkill list的输出:
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
这是dmesg 的输出,我认为它与所有这些都有关:

我不知道如何解决这个问题,我已经尝试安装了几个与这个问题相关的新闻中建议的驱动程序,但都没有成功。有什么建议吗?
