我是 ubuntu 新手，自从 90 年代上大学以来就没用过 UNIX。我刚刚安装了 12.04，更新后，它可以正常连接到我的家庭无线网络。
不幸的是，在工作中没有这样的运气。我尝试了所有能想到的方法，并在这里和其他地方搜索了太多可能的答案。仍然没有运气。
当我在工作时和在家里执行 iwconfig 并进行比较时，我得到了以下结果：
$diff iwconfig_office iwconfig_home
5,6c5,6
< eth1 IEEE 802.11abg ESSID:off/any
< Mode:Managed Access Point: Not-Associated

lspci在家里和办公室是相同的。
在办公室我有一台摩托罗拉 3347 路由器；在家里有一台 Linksys WRT54GS。
在办公室，我尝试了 128 位 WEP 以及个人 WPA/WPA2。都无法连接。
iwlist -scan (note that wyolution2 is the connection I'm trying to use):
eth0 Interface doesn't support scanning.

注意：我已经有六台设备连接到此无线接入点，包括 Android 设备、W7 和 W8。此外，这台特定的机器在被重新用作 Ubuntu 盒子之前也曾连接到过它。
任何建议都将非常感谢！

如果有人正在阅读此帖子，我想更新解决方案。我将系统移至 3.10，无线 WPA/TKIP 运行正常。
