wpa_supplicant 不再连接到 eduroam

几周后（可能在 dist 升级之后）我的机器无法再连接到 802.1x 网络。我使用 Debian Buster 和 i3，但使用 nm-applet。我也尝试过直接与 wpa_supplicant 连接，但它也不起作用。这是我的配置：

[connection]
id=eduroam
uuid=a86d2f21-990c-4a55-b7e4-933ffcffe0cd
type=wifi
permissions=user:root:;

password=[secret]
phase2-auth=mschapv2

[ipv4]

method=auto

[ipv6]

这是系统日志的输出：

除了等待更新我还能做什么？

更新，dmseg -wL 输出：

更新：似乎问题是 wpa_supplicant 2.6 我通过降级到 2.4 解决了这个问题

答案1

我通过将 wpasupplicant 从版本 2.6 降级到版本 2.4 解决了该错误

答案2

我记得我的大学也遇到过类似的问题。事实证明，接入点收到了固件更新，破坏了对某些 WIFI 适配器的支持。

由于连接失败的原因是“AUTH_FAILED”而不是“WRONG_KEY”之类的原因，我会询问您的 eduroam 网络的管理员是否知道某些不兼容性。

同时，您可以检查内核日志是否包含有关 WIFI 适配器固件问题的一些信息。打开终端并dmesg -wL在尝试连接到网络时观察输出。如果您发现可疑的内容，请将其发布在这里，也许我们可以找出问题所在。

答案3

我会检查以下内容：

    systemctl list-unit-files --state=enabled
    systemctl list-units | grep -iE '(net|dhcp|wpa|conn|wicd)'

确保停止并停用所有网络管理服务并尝试手动连接： https://wiki.archlinux.org/index.php/Wireless_network_configuration#Manual_setup

这也可能有帮助：

您可能需要将 ath5k 更改为您的 wifi 卡使用相同配置文件的模块。

    echo "options ath5k nohwcrypt=Y" | sudo tee -a /etc/modprobe.d/ath5k.conf
    sudo iw reg set GB
