参考这篇文章已经解决了问题 karim-ouda.blogspot.com/2011/11/wifi-now-disabled-by-radio-killswitch.html
实际上好像他说是驱动冲突在 /etc/modprobe.d/50-blacklist.conf 中加上 blacklist acer-wmi 就好了, 感谢大家的帮助
虽然只有这一个小问题了, 但还是很让人不爽, 有时候开机后无线网卡处于禁用状态, 要按 Fn + F3 手动开启, 如果是从 sleep 状态 Resume, 无线网卡肯定是硬件禁用状态, 需要手动开启才能用,BIOS 里没有找到相关的设置 (节能什么的都没有), 应该是操作系统级别的问题, 因为其他发行版没有这个问题
我的电脑是 Acer 4750, 呼唤高手, 手弟先谢过了
我的网卡是 ather 的

友情帮顶，我这里 USB 网卡即插即用，没有问题啊
在 yast 中设置后会卡在 70% 上不动, 手动硬件开启才可以, 而且设置完了后连不上网, 是不是无线如果用系统连接还要做其它的操作
不是, 纯的 openSUSE 12.3 , 全新安装的,
请用 NetworkManager 管理您的无线网路。 
不好意思前面没明白过来, 我刚试了设置成系统连接没有用, 合上笔记本的盖子再打开网络还是禁用状态, 要手动开启
这样就是不是网路问题了。应该是内核 ACPI 或者驱动的问题。
像置顶帖里那样贴一下
sudo hwinfo --wlan --short
的结果看看你具体啥型号吧。
–short 的内容太少了, 直接来个全的

我更新到文章正文中了, 简单说就是驱动冲突了, 把 acer 的禁掉就好了
首先，应该是 SOLVED 而不是 resolved
其次，混论坛都不会用 bbcode 么代码贴那么长难看死了
。。。又不是自己写的论坛程序可以用 markdown 啊
