hostap problems with Macintosh 802.11g users

[DMZ]

Hello,
  I am having a problem with my dlink 520+ running host_ap 2002-10-12 on linux 2.4.18 kernel. 
The problem only appears with Macintosh OSX users using the new AirPort Extreme 802.11G adapter card.
The card is suppose to step down to 802.11b compatable if it doesn't find a G network.
However it doesn't appear to be doing that.

One of the MAC users who also has a home d-link router suggested the following:
The problem is that it has a Tx rate of 22, which apparently  Airport Extreme
tries to interpret as a 11G signal.  The  configuration panel for the DLink
allows you to change from  1-2-5.5-11-22 to 1-2-5.5-11.  Then Airport
Extreme works fine.


Here is what I see from my dmsg output:
wlan0: 00:03:93:e9:68:e4 auth (alg=0 trans#=1 stat=0 len=6fc=00b0) ==> 0 (authenticated)
wlan0: 00:03:93:e9:68:e4 assoc (len=32 prev_ap=00:00:00:00:00:00) => 1(0) (SUPP_RATES len error)

wlan0: sending deauthentication info to STA 00:03:93:e9:68:e4(last=4045542, jiffies=4075742)

As you can see, host_ap does see the card. It is just having SUPP_RATES len errors leading, i assume, to 
a disassociation with the AP.

Here is the iwconfig of my dlink card:
wlan0   IEEE 802.11-b  Nickname:"zrnetservice"
        Mode:Master  Frequency:2.432GHz  Access Point: 00:05:5D:F9:F8:DE

Any suggests extremely welcome!
