RT5572 可以使用 WPA2 进行身份验证，但无法从 DHCP 获取 IP 地址

我有一个运行开放式嵌入式 Linux 的系统，带有 Ralink RT5572 无线 USB 卡。我安装了驱动程序和 wpa_supplicant，我需要能够连接到 WPA2 安全网络。据我所知，我可以使用正确的配置启动接口，几秒钟后它就会进行身份验证。我在 Wireshark 上看到来自设备的 2 个身份验证数据包，日志显示它已通过。此时我想在接口上运行 udhcpc 或 dhclient 以获取 IP 地址，但它们都不起作用。我没有在网络上看到来自该设备的更多数据包。我还尝试设置静态 IP，但即使这样，我也无法 ping 网关或网络上的任何其他计算机。

这是我的 wpa_supplicant.conf 文件：

ctrl_interface=/var/run/wpa_supplicant
update_config=1
ap_scan=1

network={
    ssid="HTC One M9 8506"
    psk=###########################################
    scan_ssid=1
    key_mgmt=WPA-PSK
    proto=WPA2
    pairwise=CCMP TKIP
    group=CCMP TKIP
    auth_alg=OPEN
}

这是我的来自 wpa_supplicant 的日志：

是否有人见过这样的问题：您可以进行身份​​验证，但之后的任何数据包都无法通过？

答案1

这最终是一个驱动程序问题。我使用的是 Mediatek 的驱动程序，它是 rt5572 的芯片制造商。我改用了 SparkLAN 的驱动程序，它是我使用的实际 USB Wifi 卡的生产商，上面有 rt5572。它们看起来是相同的驱动程序，但 SparkLAN 一定做了一些调整。交叉编译和安装 SparkLAN 驱动程序使 WPA2 可以正常工作。

确实如此。我在使用基于 RT3572 和 RT5572 的 USB WLAN 适配器以及 Cisco Systems（WLC 2500 商务系列）、Hirschmann 和 Symbol Technologies 的一些接入点时遇到了这个问题。我通过切换到 rt2800usb OSS 社区驱动程序暂时解决了这个问题，但与 RTxxxxSTA 制造商驱动程序相比，该驱动程序的性能相当差。您的解决方案也适用于基于 RT3572 和 RT5572 的适配器。非常感谢！:)
