Thanks for your explanation. I checked my access point (a Linksys WRT54LG running dd-wrt) and there is no mention of "shared" or "open" that I can see.

It seems from this that "open" means "no key" and "shared" means "key". I've found that I can usually force NM to work as I wish by editing ~/.kde/share/config/knetworkmanagerrc . However, I don't consider this is very satisfactory. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland _______________________________________________ NetworkManager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
