我买了一个 Wifi USB 密钥，以便将我的工作站连接到 Wifi。它工作了大约一周，然后，他尝试进行身份验证，但无法进行身份验证（系统提示我输入密码 3 次（密码正确），但失败了）。
我在 Fedora 17 x64 上，我的密钥是 NETGEAR WNA3100M

我不知道发生了什么，是不是密钥出了问题，或者是内核更新了，但是现在，我迷路了 :/
你知道发生了什么吗？谢谢！:)
答案1
每次我升级操作系统时，使用另一个 WiFi USB 密钥在 Ubuntu 上也会发生类似的事情。您最近是否安装了任何更新或更改了内核？
无论如何，我总是能够在每次更新后通过重新编译 USB 密钥驱动程序来修复它。
答案2
我终于将 Fedora 更新到了最新版本（我迟到了 n-1），密钥又开始起作用了。我猜想上一个版本中有一些未修复的错误没有更新。
我查看了@user1301428 的回答，因为如果您想要（出于任何特殊原因）保留在 n-1 版本的 Fedora，您可能必须使用此方法。
但如果可以的话，我强烈建议您将版本更新到最新版本。
答案3
如果驱动程序是官方 Fedora 驱动程序，则根本不需要重新编译驱动程序等。根据显示的日志，驱动程序似乎正在运行。
如果您更新了内核，Fedora 应该会保留旧内核。尝试使用以前可以正常工作的内核启动，然后再次检查。如果可以正常工作，请通过 bugzilla 报告问题。
