Question

我正在试图弄清楚在Arch上使用wi-fi这么慢的速度是什么原因。我将Windows 8与Arch一起安装，我可以肯定地说，在Windows上，速度最终会更高。当我切换回Arch并开始上网时，我觉得我的互联网速度被削减了一半！我最近使用Arch和很多我不知道的东西（特别是网络）。以下是我通常使用wpa_supplicant连接到互联网的步骤：

cat wpa.conf
network={
    ssid="Home"
    #psk="pass"
    psk=05a9b845b68a55291d1d5b94e50b9b1811706b0746d89e67f581cc5f7b88b758
}
sudo wpa_supplicant -B -iwlp10s0b1 -cwpa.conf
sudo dhcpcd wlp10s0b1

有卡片详情：

提前注意一些注意事项，请不要建议检查路由器设置（一切设置正确并在不同设备上测试），所以问题不在路由器中，也不在物理障碍物中。
