Ubuntu 20.04 iwlist 扫描：[界面] 界面不支持扫描：不支持操作

我正在使用 ubuntu 20.04 (LTS)。我无法使用 iwlist 扫描网络。

$ sudo airmon-ng
PHY    Interface    Driver      Chipset

phy0    wlp1s0      ath10k_pci  Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)


$ sudo ifconfig wlp1s0up
$ sudo airmon-ng start wlp1s0

Found 4 processes that could cause trouble.
Kill them using 'airmon-ng check kill' before putting
the card in monitor mode, they will interfere by changing channels
and sometimes putting the interface back in managed mode

    PID Name
    601 avahi-daemon
    606 NetworkManager
    647 wpa_supplicant
    651 avahi-daemon

PHY Interface   Driver      Chipset

phy0    wlp1s0      ath10k_pci  Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

        (mac80211 monitor mode vif enabled for [phy0]wlp1s0 on [phy0]wlp1s0mon)
        (mac80211 station mode vif disabled for [phy0]wlp1s0)

$ sudo iwlist wlp1s0mon scanning
wlp1s0mon  Interface doesn't support scanning : Operation not supported

这不同于这问题。我已经尝试了所有建议的答案。

$ sudo iw dev wlp1s0mon scan ap-force
command failed: Operation not supported (-95)

$ rfkill list all
0: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no

答案1

此 WLAN 适配器 (Qualcomm Atheros QCA9377) 不支持混杂模式（又名监控模式）。你有两个选择：

  1. 您可以花费不到 70 美元轻松获得一张 Alfa 卡。
  2. 您可以降级 Atheros 固件，但不能保证。
