Wifi 立即断开

您好，我在 Ebay 购买的 x220 上安装了 qubes。现在我遇到了wifi无法连接的问题。 Qubes 使用 sys-net VM 来基于 fedora 29 进行互联网连接。尽管也安装了 wpa_supplicant，但它使用网络管理器进行连接。以太网与 LAN 电缆配合使用效果良好，但问题是 wifi 无法立即连接或断开。适配器是 Centrino Advanced-N 6205。我可以使用 wpa_supplicant + dhclient 连接到 wifi，如此处所述https://www.linuxbabe.com/command-line/ubuntu-server-16-04-wifi-wpa-supplicant

然而，其他 qube 无法使用此连接，我也不想使用 wpa_supplicant，而是使用 NetworkManager。也许这里有人可以帮助我找出导致 NetworkManager 拒绝保持连接的原因。我尝试按照此建议将 DHCPlient 更改为 dhclienthttps://www.linuxquestions.org/questions/slackware-14/networking-connects-then-disconnects-with-14-2-ar9285-4175583671/和这里https://wiki.archlinux.org/index.php/NetworkManager。但这也没有帮助。不知道是不是因为qubes环境的原因所以设置不一样。我还将 IPv6 设置忽略并仅通过 IPv4 连接 - 没有帮助，反之亦然。当我在网络管理器设置中“禁用”IPv4 并将 IPv6 设置为“忽略”时，我能够连接到 wifi，但是 CPU 的使用率非常高，而且显然我没有可用的互联网连接。

这是 dmesg 输出的一部分：

答案1

我找到了解决方案。

显然，补救措施是更新 Fedora 模板。但也许有人搜索需要将 /etc/NetworkManager/conf.d/dhcp-client.conf 更改为 [main] dhcp=dhclient 如下所述： https://www.linuxquestions.org/questions/slackware-14/networking-connects-then-disconnects-with-14-2-ar9285-4175583671/ https://wiki.archlinux.org/index.php/NetworkManager
