wpa_supplicant不再连接到eduroam

Question

由于几个星期(可能是在dist升级之后)，我的机器无法再连接到802.1x网络。我用的是和i3，但是使用的是.我还尝试直接与wpa_supplicant连接，但也不起作用。这是我的配置：

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

[wifi]
mac-address-blacklist=
ssid=eduroam

[wifi-security]
group=ccmp;tkip;
key-mgmt=wpa-eap
pairwise=ccmp;
proto=rsn;

[802-1x]
altsubject-matches=DNS:nps1.unitn.it;DNS:nps2.unitn.it;DNS:nps3.unitn.it;
anonymous-identity=
ca-cert=/root/.cat_installer/ca.pem
eap=peap;

password=[secret]
phase2-auth=mschapv2

[ipv4]
dns-search=
method=auto

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
method=auto

这是syslog的输出：

除了等待更新之外，我还能做些什么？

dmseg -wL输出：

更新:看来问题是wpa_supplicant 2.6我通过降级到2.4来解决了这个问题

Answer 1

我将wpasupplicant从2.6版降级到2.4版，从而解决了这个问题。

Answer 2

我记得我的大学也遇到过类似的问题。结果发现，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”，所以我会问您的eduroam网络管理员是否知道某些不兼容问题。

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，查看dmesg -wL的输出，同时尝试连接到网络。如果你发现可疑的东西，请把它贴在这里，也许我们可以找出出了什么问题。

Answer 3

我要检查以下几点：

    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_网络_configuration#Manual_设置

这也可能有助于：

您可能需要将ath5k更改为您的wifi卡在配置文件中使用的模块。

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