android - Android 连接 WiFi 企业网络 EAP(PEAP)

Question

在过去的几天里，我一直在尝试以编程方式将我的 android 设备连接到企业网络，但没有成功，我一直在网上关注多个示例，但我发现的大多数示例都是针对 EAP(TLS) 网络和我工作的地方是EAP(PEAP)，这里是网络类型。

802.1x 接入点

EAP 方法:PEAP

阶段 2 身份验证:MSCHAPV2

身份验证总是失败，logcat 没有告诉我问题出在哪里我只知道在执行身份验证时它失败了。

这是我当前代码的副本以及失败时 logcat 的日志:

我无法在网上找到有关以编程方式进行 EAP (PEAP) 身份验证的示例，我尝试更改 WiFi 配置但没有成功。关于如何连接到企业网络 EAP (PEAP) 的任何想法或有用的站点/示例，或者有人可以指出我正确的方向吗？

Answer 1

最后，我打败了我的 CiSCO EAP-FAST 公司 wifi 网络，我们所有的 Android 设备现在都可以连接到它。

为了从 Android 设备访问此类网络，我执行的绕行操作比您想象的要简单。

Google Play 商店中有一个 Wifi 配置编辑器，您可以在设置 EAP wifi 连接时使用它来“激活”辅助 CISCO 协议(protocol)。

它的名字是 Wifi Config Advanced Editor。

• 首先，您必须手动设置无线网络，尽可能接近“官方”公司 wifi 参数。

• 保存。

• 转到 WCE 并编辑您在上一步中创建的网络的参数。

• 您应该激活 3 或 4 个系列的设置，以强制 Android 设备使用它们作为连接方式(我认为您想要访问的主要站点是企业配置，但不要忘记检查所有参数以在需要时更改它们。
  作为建议，即使您有 WPA2 EAP-FAST 密码，也请在您的设置中尝试 LEAP。它对我来说很有魅力。

• 完成编辑配置后，转到主 Android wifi Controller ，并强制连接到此网络。

• 请勿再次使用 Android wifi 界面编辑网络。

我已经在 Samsung Galaxy 1 和 2、Note 移动设备以及 Lenovo Thinkpad 平板电脑上对其进行了测试。
