我正在使用一个TP-Link AV-500电源线适配器套件可在我家的一部分提供无线 AP。它通过电源线连接到我的主路由器。然而，我的笔记本电脑运行 64 位 Arch Linux，无法连接到它。
其他设备（Android 手机、iPhone、Android 平板电脑）可以毫无问题地连接。笔记本电脑可以完美地连接到路由器和其他接入点（包括 5Ghz 网络），但尽管它可以看到 TP-Link 接入点，却无法连接到它。以下是来自的相关部分dmesg：

我已禁用 TP-Link 上的安全性，因此这不是身份验证问题。设置为“11bgn混合”模式：

我也尝试过wl驱动程序：
$ sudo modprobe -r brcmsmac
$ sudo modprobe wl
$ sudo modprobe lib80211
这也无法连接，但给出了不同的错误：

按照 GAD3R 的建议，我尝试通过添加ipv6.disable=1到options中的行/boot/loader/entries/arch.conf、注释掉任何 IPv6 行/etc/hosts并重新启动来禁用 IPv6。没有不同。
我怎样才能将这台机器连接到这个网络？
