VirtualBox中Linux虚拟机无线适配器可见但无法扫描连接WiFi的问题求助

大家好，我碰到一个棘手的问题：我的VirtualBox Linux虚拟机目前只能通过宿主机的以太网联网，但无线适配器没法扫描到WiFi信号。

我执行ifconfig命令查看时，确实能看到无线适配器wlan0的存在，具体输出如下：

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

inet 10.0.2.6  netmask 255.255.255.0  broadcast 10.0.2.255

TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

另外，我把适配器切换到监听模式时，状态看起来是正常的（刚才打错命令写成wconfig了，实际是iwconfig），输出如下：

lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11  Mode:Monitor  Frequency:2.412 GHz  Tx-Power=20 dBm

Retry short limit:7   RTS thr=2347 B   Fragment thr:off

Power Management:off

但核心问题是，系统的WiFi列表里根本看不到这个无线适配器，没法进行扫描和连接操作。有没有大佬能帮忙分析下原因，给点解决思路呀？
