I installed fedora 15 connected to wireless network and start updating , then restart
When I disconnect from this wireless network , I can't join any other network !!!

although when I click a network a file is created in network-scripts folder int /etc/.. having the same name as the network
wired networks work fine
I need help , sick of linux maybe i'll try free bsd and rely on my ipod for media

and by the way I disabled network manager ant try to connect using iwconfig , also some weird error about SET fail ...
oh and I search google for this , many similar posst on fedora's forum but without solutions or evern replies !!
