That is from the bad-ole-days. I could be wrong, but AFAIK only the ipw2x00 drivers do that anyway. I recently merged a patch to change the default for that for ipw2200 into wireless-testing. We should probably have one for ipw2100 as well. Anyway, there are module options for those. Add "options ipw2200 associate=0" to /etc/modprobe.conf. Hth! John -- John W.
