Farallon SkyLINE 11Mb partial incompatibility ?

[Sorin PAUN]

Does anyone tested this card before ? Seems to work fine for hostap, but :
-at only 2Mbs in Managed & Adhoc modes
-at only 11Mbs in Master mode

in fact, iwconfig <dev> rate doesn't have any effect...

And, the second problem, is that I can't set the roaming mode 2... when 
I do:

  prism2_param wlan0 host_roaming 1

I get a SWSUPPORT mismatch error and others like this

wlan0: hfa384x_cmd: entry still in list? (entry=c35a7760, type=0, res=0)
wlan0: hfa384x_cmd: command was not completed (res=0, entry=c35a7760, 
type=0, cmd=0x0121, param0=0xfce2)
wlan0: hfa384x_set_rid: CMDCODE_ACCESS_WRITE failed (res=-110, rid=fce2, 
len=8)
wlan0: JoinRequest failed

The strange thing is that it doesn't happen always, it worked for a long 
period and it worked two times some days ago.
