升级到13.1，无线网卡连不上路由器了

Yei

之前还用得好好的，升级完就不能用了。最诡异的是用iwconfig试了N次居然还连上去过一次，用了一晚上，之后再也没连上过了。连接使用的命令如下：

2. iwconfig wlan0 essid linksys enc restricted key 2A4BDB20EC5A0E58E064B81ABA
3. dhclient wlan0

复制代码

这是开机的错误提示：


下面是dmesg | grep -i usb 的输出

补充一下，无线网卡和路由器都是好的。
rc.inet1.conf和13.0一样的设置没有动过

vvoody

升级以来还没用过无线网卡... 不知道下面的讨论对你有帮助没

你把eth0关了再用dhclient wlan0.....

Yei

谢谢两位的回答！
eth0关了似乎不起任何作用。
装了个wicd，根本找不到无线网络。奇怪的是从这之后居然又能通过iwconfig连上了，不过很不稳定，经常会掉，感觉只要很短时间内没有数据传输就掉了。一直开个ping就不会掉。从Conky的显示里可以看出，能连上的时候显示的无线速度是11M（我的无线路由是11M的），变成1M的时候就连不上了。
还有发现就是以前无线除了wlan0之外还会有个wmaster0（用slackware13的时候，那时候能连上），现在没有了
以上写得有点乱，因为我实在也没搞清楚怎么回事。有懂的麻烦指点下，多谢了！
