Re: [Madwifi-users] Can't setting 11b mode when channel has setted in madwifi-0.9.4

[Xiaochen Z. <zho...@h3...>]

I modified the code to avoid the mode checking. So the channel and 11b mode are setting OK both. When I connect my windows wireless card to this Madwifi AP, it's successful and the rate change to 11Mbps.

So I think this maybe a bug of Madwifi.

  Hi, All

  When I set channel, setting 11b mode is not OK. 

  ------------------------------------------------------------------------------------
  Fedora core 4, madwifi 0.9.4.
  ------------------------------------------------------------------------------------
  [root@wifi ~]# wlanconfig ath0 destroy
  [root@wifi ~]# wlanconfig ath0 create wlandev wifi0 wlanmode ap
  ath0
  [root@wifi ~]# iwconfig ath0 essid "wifi" channel 6
  [root@wifi ~]# iwpriv ath0 mode 11b
  Interface doesn't accept private ioctl...
  mode (8BE2): Invalid argument
  ------------------------------------------------------------------------------------
  [root@wifi ~]# wlanconfig ath0 destroy
  [root@wifi ~]# wlanconfig ath0 create wlandev wifi0 wlanmode ap
  ath0
  [root@wifi ~]# iwconfig ath0 essid "wifi"
  [root@wifi ~]# iwpriv ath0 mode 11b
  [root@wifi ~]#
  ------------------------------------------------------------------------------------

  I browse the source code(and add some printk), and find If I did not set channel, the ieee80211_check_mode_consistency() checking is OK and the ieee80211_channel is "IEEE80211_CHAN_ANYC". 

  When I set the channel, ieee80211_check_mode_consistency() checking is ERROR and the ieee80211_channel is "IEEE80211_CHAN_PUREG".

  Can somebody explain this? I think setting channel and mode both is reasonable.

  Thanks!
