Ubuntu 20.04 上的无线身份验证问题

问题描述：

我无法连接到任何无线网络，到目前为止，我已经在 5GHz 和 2.4GHz 频段上测试了 3 个网络。每次测试我都注意到连接会在身份验证阶段停止，因为 Ubuntu 能够毫无问题地找到并搜索网络。只有在身份验证时，它才会出现问题。

每次我尝试通过 gnome 和网络管理器 gui 登录时，它都会要求输入密码，尝试连接，然后再次要求输入密码，而 GUI 中不会出现任何错误消息。

有关我的设备的一些信息：

  • 操作系统：Ubuntu 20.04（昨天安装）
  • 笔记本电脑: 华硕 TUF FX505D
  • 无线驱动程序: RTL8822CE
  • wpa_supplicant 版本：v2.9

我为 realtek 加载的驱动程序如下（来自lsmod | grep rtw）

rtwpci                 24576  0
rtw88                 610304  1 rtwpci
mac80211              843776  2 rtwpci,rtw88
cfg80211              704512  2 mac80211,rtw88

我尝试过的一些方法：

  • 重新安装 wpa_supplicant ( sudo apt reinstall wpasupplicant)
  • 尝试了 3 个不同的网络（2.4GHz 和 5GHz 之间变化）
  • 尝试使用 wpa_supplicant 进行手动连接（见下文）

为了直接从 wpa_supplicant 获取日志，我使用了遵循脚本尝试验证我的无线网络（SSID 和 PASSWORD 被替换为网络的实际 SSID 和密码）。

sudo systemctl stop NetworkManager.service
wpa_passphrase SSID PASSWORD > network.conf
sudo wpa_supplicant -Dnl80211 -iwlp4s0 -cnetwork.conf

由此，我得到以下输出：

其他设备可以完美地连接到所述无线网络。这是 Ubuntu 的全新安装，其中几乎没有任何内容。任何帮助都将不胜感激！
