本文详细介绍linux操作系统中如何配置并使用无线网卡

  Link Quality:0 Signal level:0 Noise level:0

  Rx invalid nwid:0 invalid crypt:0 invalid misc:2

  其中ESSID:"default" 就是你现在的ESSID。

  检查使用的channel:

  [root@wanghao root]# iwlist eth1 channel

  Warning: Driver for device eth1 has been compiled with version 14

  of Wireless Extension, while this program is using version 11.

  Some things may be broken...

  eth1 14 channels in total; available frequencies :

  Channel 01 : 2.412 GHz

  Channel 02 : 2.417 GHz

  Channel 03 : 2.422 GHz

  Channel 04 : 2.427 GHz

  Channel 05 : 2.432 GHz

  Channel 06 : 2.437 GHz

  Channel 07 : 2.442 GHz

  Channel 08 : 2.447 GHz

  Channel 09 : 2.452 GHz

  Channel 10 : 2.457 GHz

  Channel 11 : 2.462 GHz

  Current Frequency:2.437GHz (channel 06)

  下面对它进行更改:

  [root@wanghao root]# iwconfig eth1 essid 22e6da

  其中22e6da 是我的另外一个Access Point的ssid

  检查更改结果:

  [root@wanghao root]# iwconfig eth1

  Warning: Driver for device eth1 has been compiled with version 14

  of Wireless Extension, while this program is using version 11.

  Some things may be broken...

  eth1 IEEE 802.11-DS ESSID:"22e6da" Nickname:"wanghao"

  Mode:Ad-Hoc Frequency:2.412GHz Cell: 00:02:2D:22:E6:DA

  Bit Rate:11Mb/s Tx-Power=15 dBm Sensitivity:1/3

  Retry limit:4 RTS thr:off Fragment thr:2347 B

  Encryption key:off

  Power Management:off

  Link Quality:0 Signal level:0 Noise level:0

  Rx invalid nwid:0 invalid crypt:0 invalid misc:3

  检查更改后使用的channel:

  [root@wanghao root]# iwlist eth1 channel

  Warning: Driver for device eth1 has been compiled with version 14

  of Wireless Extension, while this program is using version 11.

  Some things may be broken...

  eth1 14 channels in total; available frequencies :

  Channel 01 : 2.412 GHz

  Channel 02 : 2.417 GHz

  Channel 03 : 2.422 GHz

  Channel 04 : 2.427 GHz

  Channel 05 : 2.432 GHz

  Channel 06 : 2.437 GHz

  Channel 07 : 2.442 GHz

  Channel 08 : 2.447 GHz

  Channel 09 : 2.452 GHz

  Channel 10 : 2.457 GHz

  Channel 11 : 2.462 GHz

  Current Frequency:2.412GHz (channel 01)

  然后在ping一下你的其他计算机的地址。如果正常,试验完成。

  这里只是向大家简单的介绍了一下linux 如何配置无线网卡的简单步骤。
