无法在具有 WPA/WPA2 安全性的企业网络上使用 Android。总是断线？
我的 Nexus One (Gingerbread) 和 Samsung Galaxy Tab (Honeycomb) 均停止连接到使用 WPA/WPA2 无线连接的公司网络。奇怪的是，这两台设备至少工作了 2-3 周，然后它们（在不同的时间）开始经历一个奇怪的扫描 -> 身份验证 -> 连接 -> 断开连接阶段.在最后一个阶段之后，它显示已禁用，使用 802.1x EAP 保护。
谷歌搜索后，似乎有很多未解决的问题（例如这里，此处以及至少 5 个其他内容）与此问题相关。因为我的两台设备在此之前都可以正常工作，所以我想知道可能出了什么问题。显然，长按无线点并选择忘记网络，然后重新输入网络详细信息并没有帮助，因此必须有其他方法来执行此操作（可能是应用程序？）。有什么建议吗？
我能做什么：
我的 Nexus One 已获得 root 权限，因此我可以删除任何 .conf 文件。唯一的问题是我的 wpa_supplicant.conf 没有任何连接特定信息
我不能做什么：
更改与接入点相关的任何内容，因为它不在我的控制之下。从我读过的所有错误报告来看，这个问题肯定是客户端问题。
My Nexus One (Gingerbread) and Samsung Galaxy Tab (Honeycomb) both stopped connecting to my corporate network that uses WPA/WPA2 wireless connections. What is strange is that, both the devices worked for at least 2-3 weeks before both of them (at different times) started going through a strange Scanning->Authenticating->Connecting->Disconnected phase. After the last phase, it shows Disabled, secured with 802.1x EAP.
Upon Googling, there seems to be a number of open tickets (e.g. here, here and at least 5 others) related to this problem. Because both my devices were working before this, I was wondering what could have gone wrong. Obviously, long-pressing on the wireless point and selecting Forget Network and then re-entering the network details is not helping so there must be some other way of doing this (possibly an application?). Any suggestions?
What I can do:
My Nexus One is rooted so I can probably delete any .conf files. The only problem is that my wpa_supplicant.conf does not have any connection specific information
What I cannot do:
Change anything related to the access point because it is not under my control. This problem is definitely a client-side problem from all the bug reports that I've read.

最后，经过两个月的绞尽脑汁，这是一个对我有用的解决方案。
以下假设您的 WiFi 连接无法正常工作，但您有可用于传输文件的数据线。您可能没有屏幕截图中所示的确切屏幕。这是因为我的设备使用了不同的 ROM，但总体步骤不会改变。
第 1 步：获取备用 WiFi 配置编辑器
第 2 步：修改 WiFi 设置
密钥管理WPA_EAP和IEEE8021X设置为Enabled或ON。让WPA_EAP保持原样，但关闭IEEE8021X。最后，它应该如下所示：Back按钮在您的设备上返回一个屏幕。 请勿退出应用程序！步骤 3：重新输入密码
密钥管理的屏幕中，选择企业配置。密码并输入您的密码，然后点击确定保存后退按钮三次即可退出应用程序。就是这样！如果它有效，恭喜并欢迎加入
bug-skipped潮流。如果没有，很抱歉占用您的时间。但希望谷歌能够尽快修复这个令人讨厌的错误。Finally, after two months of banging my head, here's a solution that worked for me.
The following assumes that your WiFi connection is not working but you have a data cable that you can use to transfer files. You may not have the exact screen as shown in the screenshots. That's because I am using a different ROM for my device but the overall steps will not change.
Step 1: Get an alternate WiFi configuration editor
Step 2: Modify the WiFi settings
Key ManagementWPA_EAPandIEEE8021Xare set toEnabledorON. LetWPA_EAPstay as it is but turn offIEEE8021X. In the end, it should look like the following:Backbutton on your device to go back one screen. DO NOT QUIT THE APPLICATION YET!Step 3: Re-enter your password
Key Managementfrom, selectEnterprise Configuration.Passwordand enter your password and hitOKto save itBackbutton on your device three times to exit the application.And that's it! If it works, congratulations and welcome to the
bug-skippedbandwagon. If it didn't, sorry for taking your time. But hopefully, Google will fix this nasty bug soon.
