将 Android 连接到 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) 网络和我工作的一个是 EAP（PEAP），这里是网络类型。

802.1x EAP

EAP 方法：PEAP

第 2 阶段身份验证：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 logcat 失败的日志：

这些是指示连接尝试失败的日志

我在网上找不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网站/示例，或者有人可以指出正确的方向吗？

Answer 1

最后，我击败了我的 CiSCO EAP-FAST 公司 wifi 网络，现在我们所有的 Android 设备都可以连接到它。

我为从 Android 设备访问此类网络而进行的漫游比您想象的要简单。

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“激活”辅助 CISCO 协议。

它的名字是Wifi Config Advanced Editor。

• 首先，您必须手动设置无线网络，使其尽可能接近“官方”公司 wifi 参数。

• 保存。

• 进入 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 系列设置，以强制 Android 设备使用它们作为连接方式（我认为您要访问的主站点是 Enterprise Configuration，但不要如果需要，忘记检查所有参数以更改它们。
  作为建议，即使您有 WPA2 EAP-FAST 密码，也请在您的设置中尝试 LEAP。它对我来说是一种魅力。

• 完成配置编辑后，转到主 Android wifi 控制器，并强制连接到此网络。

• 不要再次使用 Android wifi 界面编辑网络。

我已经在三星 Galaxy 1 和 2、Note 移动设备以及联想 Thinkpad 平板电脑上对其进行了测试。

感谢您启发我们 Cypawer。

我也试过这个应用https://play.google.com/store/apps/details?id=com.oneguyinabasement.leapwifi

它完美地工作。

Answer 3

我正在尝试在我的程序中连接公司的 eap wifi。

前置条件：

1.让 IT 人员将您设备的 mac 地址添加到网络配置中。

2.我的网络配置：

EAP method:PEAP

Phase2MethodVerify:NULL

CACertificateVerify:NULL

Identity:""

Password:""

首先，我添加了一些登录设置，这样我就知道点击wifi提交按钮时发生了什么。

打印如下：

* ID: -1 SSID: "SSID" PROVIDER-NAME: null BSSID: null FQDN: null PRIO: 0 HIDDEN: false
 NetworkSelectionStatus NETWORK_SELECTION_ENABLED
 hasEverConnected: false
 KeyMgmt: WPA_EAP IEEE8021X Protocols:
 AuthAlgorithms:
 PairwiseCiphers:
 GroupCiphers:
 PSK: 
Enterprise config:
password <removed>
ca_path NULL
engine 0
proactive_key_caching 1
client_cert NULL
anonymous_identity NULL
ca_cert NULL
identity "name"
domain_suffix_match NULL
key_id NULL
engine_id NULL
IP config:
IP assignment: DHCP
Proxy settings: NONE
 cuid=-1 luid=-1 lcuid=0 userApproved=USER_UNSPECIFIED noInternetAccessExpected=false isCarrierNetwork=false roamingFailureBlackListTimeMilli: 1000
triggeredLow: 0 triggeredBad: 0 triggeredNotHigh: 0
ticksLow: 0 ticksBad: 0 ticksNotHigh: 0
triggeredJoin: 0

我在代码中的配置是：

            config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);

        config.enterpriseConfig.setEapMethod(WifiEnterpriseConfig.Eap.PEAP);
        config.enterpriseConfig.setPhase2Method(WifiEnterpriseConfig.Phase2.NONE);
        config.enterpriseConfig.setCaCertificate(null);
        config.enterpriseConfig.setAnonymousIdentity(null);
        config.enterpriseConfig.setDomainSuffixMatch(null);

        String ssid = "";
        String psw = "";
        config.enterpriseConfig.setIdentity(ssid);
        config.enterpriseConfig.setPassword(psw);

它会这样打印：

    * ID: -1 SSID: "SSID" PROVIDER-NAME: null BSSID: null FQDN: null PRIO: 0 HIDDEN: false
 NetworkSelectionStatus NETWORK_SELECTION_ENABLED
 hasEverConnected: false
 KeyMgmt: WPA_EAP IEEE8021X Protocols:

Enterprise config:
anonymous_identity NULL

IP config:

Proxy settings: UNASSIGNED
 cuid=-1 luid=-1 lcuid=0 userApproved=USER_UNSPECIFIED noInternetAccessExpected=false isCarrierNetwork=false roamingFailureBlackListTimeMilli: 1000
triggeredLow: 0 triggeredBad: 0 triggeredNotHigh: 0
ticksLow: 0 ticksBad: 0 ticksNotHigh: 0
triggeredJoin: 0

终于成功了~
