我有一张 Intel AX201NGW 蓝牙 + WIFI 卡,连接到主板上的 M2 插槽。安装后,Ubuntu 20 检测到卡正常,并且我得到了连接对话框,在设置图标中显示“蓝牙”(之前没有),在 Wi-fi 下显示一张 Intel 卡。但是,要连接的列表中没有 WIFI 网络或蓝牙设备。
根据英特尔的建议,我安装了从这里并安装sudo tar xvzf iwlwifi-qu-48.13675109.0.tgz -C /lib/firmware
。重启后,WIFI卡消失,蓝牙仍然不起作用。
一个可能令人困惑的问题是我没有将天线连接到卡上。有人知道这是否仍可用于没有天线的蓝牙吗?
更新: 重启后,WIFI 又出现了。仍然看不到任何网络或蓝牙设备。
更新:一些诊断的输出:
