关于ipw3945无线网卡配置问题

yukun84

总算把各种杂七杂八的驱动装上了，但配置后似乎还是无法连上路由器。使用ifup eth1能够激活无线网卡

使用iwconfig显示：

eth1      unassociated  ESSID: off/any  Nickname:"localhost.localdomain"
          Mode:Managed  Frequency=2.412 GHz  Access Point: Not-Associated   
          Bit Rate: 0 kb/s   Tx-Power:14 dBm   
          Retry limit:15   RTS thr: off   Fragment thr: off
          Encryption key:4875-6D61-6E62-696C-6C38-3838-31   Security mode: open
          Power Management: off
          Link Quality: 0  Signal level:0  Noise level:0
          Rx invalid nwid: 0  Rx invalid crypt:0  Rx invalid frag: 0
          Tx excessive retries: 0  Invalid misc:85   Missed beacon:0


我用的无线路由上的网，不知道这样配置有没有什么问题？密码是对的。

请各位高手帮我看看。

运行
$ iwlist scanning
然后根据输出来设置无线网卡就可以了，可以在图形界面下设置。

如果还不太清楚，
把你的 "iwlist scanning"输出贴出来看看

以下是图形设置界面的截图。不知道为什么我设置好TP-LINK在iwconfig中看到的却是TP-LINKI

cswei

try
# iwconfig eth1 essid TP-LINK

I couldn't see your uploaded image. Did you activate your eth1 in Network Manager?

你的通道应该是设为 6
呵呵，看到你的 iwlist scanning 里边的输出是 Channel: 6

yukun84

非常感谢yichi！
刚试了一下发现能上网了，立马来这回个贴。哈哈。

对了，这个通道是什么意思呢？为什么在WINDOWS下不需要设置它？

MS-Windows detected it automaticly, just like `iwlist scanning` command under Linux box.


Each channel has a slightly different frequency. Changing the wireless channel on your router will change the frequency being used and may assist in avoiding interference from other devices.


Wireless routers can broadcast on several different channels, similar to the way radio stations use different channels. In the United States and Canada, these channels are 1, 6, and 11. Just like you'll sometimes hear interference on one radio station while another is perfectly clear, sometimes one wireless channel is clearer than others. Try changing your wireless router's channel through your router's configuration page to see if your signal strength improves. You don't need to change your computer's configuration, because it'll automatically detect the new channel.

好,回去也给我的无线网卡装个驱动.
