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.

Changing the channel should (and does) trigger reassociation, but only if there is an SSID to associate with! In plain english, this if statement should read: "If associate=0, and no locked SSID or locked BSSID have been set, don't associate" > becouse networkmanager do not set channel=0 to be compartibel with other > drivers. wpa_supplicant sets (or doesn't set) the channel, not NM...
